Firemin

One of the biggest “improvements” that Mozilla claims is 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 I created Firemin.

Memory Leaks

We like keeping our apps running for a few days (that’s just the way I roll) and because of this Firefox was using over ~800MB of memory after about 3 days. It’s quite normal for Firefox to be sucking up over 200MB 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.

Enter Firemin

Rather than complain about it, we decided to fix it. Enter Firemin; simply put, it 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 (including Firefox extensions) and all the memory leaks was gone.

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 4612

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.

    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.

    Firemin is Best Firefox App yet!!!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.

    Somewhat dissapointedWell 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.
    I use Windows 7 with 4 GB of ram.

    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.

    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.

    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!!!

    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.

    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…

    Reply
    1. Rizonesoft Post author

      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).

    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: 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.
