One of the biggest “improvements” that Mozilla claims are the Firefox memory usage, in particular, the vanquishing of memory leaks. Although Firefox memory usage improved a little over the last few years, it still uses a lot of memory; a little more than I feel comfortable with. And for this reason, we created Firemin.

Programs on my computer can stay open and run for days or even weeks, and Firefox is no exception. Because of this Firefox was using over 3 GB of memory after a few days. It’s quite normal for Firefox to be sucking up over 250 MB of memory right off the bat. In a memory leak, you’ll see the memory usage keep increasing the longer the program is open/in-use and this is exactly what happens with Firefox.

What is Firemin?

Simply put, Firemin will attempt to eliminate Firefox memory leaks and decrease the amount of memory Firefox uses. All I did was tweak our Memory Booster a little and applied it to Firefox and this solved the memory leak issues.

Firemin vs. Windows Memory Management

Windows will also periodically scan running processes and tell them to release their unused memory. You could argue that this makes Firemin unnecessary, and you would be spot on. However, It is my opinion that Windows does not clean out memory as often as I would like it to. Firemin runs the clean memory API call a few times per second.

Firemin Build 4982 main screen

The method Firemin uses to decrease Firefox memory usage is not proven and the debate over if it works or not will go on until the end of time, but the logic remains; if it works for you, use it and if it does not, don’t use it. It is really that simple.

Download Firemin

Firemin comes in two flavors. A setup utility for installing Firemin to your computer and a portable version for running it straight from a memory stick or portable hard drive. The portable version will not write any settings to the registry or leave any traces on your computer.

I came to our attention that all of the language files in build 5069 is corrupt. We apologize for the trouble and request that you download the fixed Build 5082.

    cam you do anything about pagefile size?

    My notebook has 2 GB RAM and 2 GB disk space on C. After one or two webpages, FF explodes the pagefile from 400MB (startup) to 1.6GB and more. Even when closing FF, that is never released. So I end up with an unusable system: FF fills the pagefile, free space on C goes to 0 and it stays 0 after closing FF and I have to reboot or try to work with 90MB free space.

    This is an awesome little app. I have been a Firefox user for 10 plus years as I love how you can customize it with the extensions/addons. Whilst other browsers also have these, firefox has the greatest number and IMO, the best. Of course with more extensions added means more memory usage so even with 16GB DDR4 RAM, it slows down over time. Firemin keeps this in check for me without having to restart the browser every hour so, Sure it is not the panacea to all the memory problems of Firefox but it is the best as it certainly helps and the easiest to use.

    Thanks, Rizonesoft

    Firemin reduced Waterfox memory usage from 9GB (!!) to less than 100 MB (with my current settings).
    Even with 32 GB available, browsing was terribly slow.
    I had no memory issues with Edge, Chrome or Opera though. (but I liked Waterfox more).
    Now I’m trying to find good settings and enjoy browsing again..

    Firemin appears to have entirely stopped working. I look at it and it doesn’t do anything. I can’t even open Firefox using it. I am not sure what is wrong, but I suspect it’s a recent Firefox update that put it out of sync.

    • Derick Payne Post authorReply

      That’s strange. Firemin is independent of Firefox updates. It references the executables, so unless that changed, then it should work with all future updates. I will need to research this a little. Have you tried re-installing Firemin?

      Also, what version of Firefox are you using. I also need your Windows version and architecture (64bit or 32bit) if you can please. I need as much information as you can give me, so we can troubleshoot together.

    my Firefox generally started at using half a GB of memory and could go up to 4GB, it was always at the top of task manager (above discord, antivirus, etc), and this just. instantly knocked it down so much that half the time it doesn’t show up without scrolling, I actually have some free ram now

    I haven’t run it long enough to see about longer periods of time yet but it had such a dramatic effect literally on installing that I have to write this and I never write comments

    I had windows 10 eating half my ram and firefox kept going up to eating the other half, but now it can actually /function/, thank you so much

    Sometime do a good thing, sometime makes firefox or other process (if you put one in extended processes list) annoyingly slow. I suppose there are to be other criteria than just heap usage and garbage collector called by timer. But do things better in my case with settings 10000ms and 200mb.

    Your description of Firemin is way too modest.

    Especially on Chrome (Windows 7), it stops the slow growing memory bloat in its tracks. Instead of seeing 200MB or more for several processes I see 20MB or 30MB. It hits 150MB when e.g., streaming a movie but as soon as the movie stops, it’s back down to 20/30 MB.

    I have had no problems with stability or interference with addons (using it a year or so) and it should be much more widely promoted for both Firefox and Chrome.

    If you made a version of Firefox using the Mozilla base, and a version of Chrome using the Chromium base, incorporated Firemin into both, and got them included in some of those “browser efficiency” comparisons you’d very quickly have the most downloaded and installed browsers.

    Maybe Mozillamin and Chromiumin?

      Although Firemin is not able to monitor both browsers, you can select your main browser and then enter the other one’s process into Extended Processes. For example; select Firefox.exe as the main browser and then enter Chrome.exe in Extended Processes.

    Went to upgrade to latest version 4890 of Firemin today and while installing, Avast Anti-Virus flagged it and would not allow me to proceed. Also, why is the file labeled “unknown publisher” after I downloaded it went to install. I still have the prior version operational, but this latest version will not install until it is analyzed and passes muster with Avast labs.

      All Rizonesoft will show “Unknown Publisher” until we get our hands on another Software Signing Certificate. We are working on it and if all goes according to plan will acquire one at the end of February. Furthermore, please read “Is Rizonesoft Software Safe?” for more about false-positives and a possible solution. Here is the VirusTotal scan: https://www.virustotal.com/#/file/dcaa9cf56fd02a358a08006bac91fa9c6d8ba6feb08e6630edc70093ba175dcb/detection As you can see the detection is a false positive.

      To report a false positive to Avast, do the following:

      Add an exclusion for Firemin in Avast. Use this contact form to submit the file: http://www.avast.com/contact-form.php. Make sure you’ve noted that it is “False Positive” or send the file to virus@avast.com. Pack the file into ZIP archive and lock it with password “virus” (without quotes) and attach it to the e-mail. Write the same password inside mail body, so the Avast analysts will know the password right away without guessing. You can also add web address to that file (or webpage of the file/program) if it’s on the internet. Add your own note on why do you think that it’s a false positive. If it was really a false positive, you will get a reply mail after some time.

      In conclusion, thank you for your support!

    season’s greetings,

    since firemin build 48xx – if you click on the icon on the task tray, the Extended Processes button does nothing, neither on win 7 or win 8.1, yet if right click the tray icon it does display the extended process panel.
    Also under Win8.1 x64 , Firemin does not auto start with windows.
    If I force the firemin file to the windows startup folder – dumb win8.1 actually copies the firemin executable to that folder and when pc starts – displays ” Fugue.dll is missing “,
    Win8.1 wont let me create a firemin.exe shortcut into the startup folder, yet will let me create a shortcut of the firemin folder into the startup folder, and pops up the folder on computer startup – go figure!. And if I copy the firemin desktop shortcut to the startup folder – windows just ignores the shortcut file…
    [ micro$oft and their annoying pedantic over-security in the recent operating systems – IF it aint a M$ product, you must re-authorize each file every time you run it under Win8.1, even though set to admin privileges – doesn’t matter how many thousand times it has been run before on the same computer – most files windows wants to block when trying to run them – including firemin and firefox etc…. ]

    Win8.1 x64, i3 cpu , AVG antivirus.

    PS
    tried FireFox 57 x64 quantum [it unfortunately auto updated],
    Too many glytches , including disabling all addons and bookmark toolbar is broken – have gone back to FF 48 …
    Anyways, FF Quantum update for some dumb reason changed the install folder to be under the “/users/../../firefox ” subfolders [win8.1 i.e. ]… so had to tell firemin where to find quantum FF

    PPS
    If when you adjust settings, why is there no [OK] button or some such to close the settings panel? Normally a [Cancel] button is there to regress, stop or undo any recent adjustments …
    … or are you supposed to assume the [X] button is to close the settings panel?

    PPPS
    I see there is a new firemin update to build 4839 today, have not yet tried that out.
    … which reminds me – often if the update notify panel has been ignored for a while, and/or the settings panel left in the background, you cannot close either panel without using right click on the tray icon to actually Close firemin – or sometimes need to forcibly close firemin with task manager… then have need to re-start firemin, even on Win7.

    Well who guess , firefox written C++ language , that memory leaks will appear.
    firemin very good app, it works superb and it is FREE, EVEN BETTER I SAY!
    Huge thanks, now i have time to save some buck for better hardware which can run some bullshit js stuff…

    Another request / suggestion — one which might be another way to customize the frequency with which Firemin does its thing, as many have requested: add a ENABLE/DISABLE selection toggle to the systray icon context menu. That way one could leave Firemin running all the time and “manually” invoke it periodically when desired. I realize this means coding the functionality into the program and I don’t know if that is easy or not, but in case it is, it would be great. Thanks.

    hi! I just downloaded Firemin. However, when I restarted PC, the warning(?) window popped up.
    its said;
    “Required resources missing(title)
    A required resource file (C:\Users\XXX\AppDaa\Local\Temp1_Firemin_4615.zip\Firemin_4615\Fugue.dll) is missing. This file keeps all the pretty icons. Why somebody would not like pretty icons is beyond me? What would you do with all this extra space?”
    I uninstalled, downloaded and installed it again. But this window popped up. How can I fix it? Did I do something wrong?

    Nice app but did a way exist to clear the ram only every 15 or 60 minutest?
    the Problem is that i play minecraft and every minute the firefox comes in foreground when i use firemin.

    Thanks a lot.

    I have a feature / functionality request. I’m testing Firemin 4 x64 w/ Firefox 54.0.1 x64 under Windows 7. I would like to be able to add a custom RAM trigger (limit) — say, 600MB. I tried editing the INI file to reflect this but it did not work (or I did it wrong). I prefer if Firemin is not triggered anywhere near as often as the current 99MB and/or 9000 millisecond settings require. If this is possible or can be worked into future releases, that’d be great.

    Wow!!!! With this app installed and working, the amount of memory that Firefox is using is unbelievably low. Glad I found this app and it will be on my computer from here on out. Before installing this app, I had times when Firefox would not respond and I had to restart it. Memory usage is changeing quite a bit, but it is still probably less than 250 meg while previously I had times when it got to 1.5 Gig and that is where it loses control and nothing further can be done to it except restart it.

    Well it works, but for some reason the hard disk usage sky rockets to 100% and it remains that way when firemin is running. So you get rid of one problem and get a new one, not much of a fix.

    When using Firemin Mozilla it slows down too much and if I use it for a while causes a memory failure and a blue screen.

        Just open Firemin window then Browse or got to folder and select firefox file “C:\Program Files\Mozilla Firefox\firefox.exe”, and don’t forget to Save your settings.

    great that has helped a lot 1 last question is there a way to have Firemin going on 2 browsers at one time for example Firefox and Palemoon my daughter and i both play a app on fb I use pale moon she uses Firefox is there a way we can have it on both browsers at the same time

    I used this for a little while until I found a solution, then didn’t need it.

    If you set Firefox’s cache limit to 0 Firefox will run so much better. Haven’t needed to use this program since! Sorry! 🙂

  82. anjira95 Reply

    I have used the software and from the Windows Task Manager, if I observe a decrease in RAM usage, but third party applications like hackerprocess I see the typical value of using Firefox RAM for daily use, (400-500 MB ). That sweats, because this difference.

  83. vakul Reply

    I love Firemin. Using it for more than a year now.

    Lately, Firefox gives a “Warning: Unresponsive script” prompt that says “A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.” Only option for me is to restart the machine. Windows 7, 64-bit, 8GB RAM.

    Please try to look into this issue if it needs addressing.

    It’s well worth the donation I made. Keep developing new stuff.

    Broken link : “Firemin 4 (Build 4615)” links to “Complete Internet Repair” instead. I had to download the portable version instead (no loss!)

  85. Ed Reply

    I installed the .exe version of *4615 on an Asus K54C laptop running Windows 7 64 with 4 Gigs of RAM today after making a system restore point. Firemin is working fine so far. Firefox memory usage has dropped from about 1 to 1.6 Gigs to about 20 Megs or less. Youtube audio seems fine as I haven’t noticed any popping yet with the default settings. All pages are loading much faster. By default Firemin is set to work with Thunderbird and when I open it with Firemin running, the mail loads instantly for me. Windows memory management has never worked on this laptop, right anyway. Firemin does work. The difference is like night and day. It also places an icon in the system tray where if you run into problems, you can exit easily. Good job and thank you.

    Finally a solution that works! Firemin works like a charm! I mean, I have been fighting with enormous memory consumption by Firefox for years and with no real effect! Until now – I found your little tool and it makes such a huge difference! It reduces memory consumption instantly, I can clearly feel this effect on my system (Windows 7 Pro, 64-bit).
    Thank you very much developers!!!

  88. John Reply

    Rizone, sent an email already regarding this issue but wanted to place it on the board as well. In summary there does seem to be an issue regarding audio when using firemin. When streaming media the audio is crackling/popping. I’ve used multiple mozilla browsers, safe modes, extension/add-on troubleshooting, cache clearing, but to no avail. I’d like to suggest providing a more dynamic range of boost intervals and memory reduction limits considering the users able to allocate more memory to it. Allowing a less frequent API call and allowing more memory to the browser would help in eliminating the sound problems. Not sure if this is a bug within the gecko engine, plugin-container, or maybe flash itself, but as the recent comment states, when firemin is closed the audio is flawless across any moz based browser. Thanks again. Hope this helps and look forward to any progress. Mozilla is great, but this tool makes it 100 times better.

    The new build is amazing with the new extended processes! The plugin-container.exe has been the biggest headache with it’s insane memory usage. I have installed scripts to limit flash, etc.. but this destroys any script I have used in the past!

    Tried Firemin 2086 today. But it looks that it does not decreas private bytes. only the working set is getting lower. See my screenshot: https://i.imgur.com/hrCOpFI.png

    FF is still using 1 GB + after a few minutes of usage…

    • Rizonesoft Post authorReply

      Firemin only need to decreas the working set. See explanation below:

      Private Bytes refer to the amount of memory that the process executable has asked for – not necessarily the amount it is actually using. They are “private” because they (usually) exclude memory-mapped files (i.e. shared DLLs). But – here’s the catch – they don’t necessarily exclude memory allocated by those files. There is no way to tell whether a change in private bytes was due to the executable itself, or due to a linked library. Private bytes are also not exclusively physical memory; they can be paged to disk or in the standby page list (i.e. no longer in use, but not paged yet either).

      Working Set refers to the total physical memory (RAM) used by the process. However, unlike private bytes, this also includes memory-mapped files and various other resources, so it’s an even less accurate measurement than the private bytes. This is the same value that gets reported in Task Manager’s “Mem Usage” and has been the source of endless amounts of confusion in recent years. Memory in the Working Set is “physical” in the sense that it can be addressed without a page fault; however, the standby page list is also still physically in memory but not reported in the Working Set, and this is why you might see the “Mem Usage” suddenly drop when you minimize an application.

    Doesn’t work

    When trying to launch firefox, it always uses “C:\program files (x86)\…” even though I set a different location.

    When trying to optimize, it hangs at “initializing”, probably as it doesn’t find Firefox’ profile directory (which I have moved out of the %appdata% folder).

    is FireMin still working as intended with the latest versions of FF ?

  97. Neil Parks Reply

    There are a few problems with finagling Firemin with Pale Moon (and possibly some of the others but I don’t have any of those). In particular, the palemoon.ini file (alone of all the listed browsers) contains two copies of the configuration. And I had to edit the last two lines of firemin.ini so that it would find Pale Moon:

    Profile=palemoon.ini
    Path=C:\Program Files (x86)\Pale Moon\palemoon.exe

    • Dan Walker Reply

      I need to edit it for palemoon but once edited it wont save… any ideas?

      • Neil Parks Reply

        @Dan Walker: Make sure that Firemin is not in memory before you edit the files. Use Windows Task Manager (ctl-shift-esc) to verify that Firemin is not running.
