Firemin is a small utility to reduce the amount of memory Firefox or other browsers use. Although Firefox memory usage improved a little over the last few years, it still uses a lot of memory; a little more than we feel comfortable with.
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 keeps increasing the longer the program is open/in use and this is exactly what happens with Firefox.
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 our opinion that Windows does not clean out memory as often as we would like it to. Firemin runs the clean memory API call a few times per second.
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.
Even though we created the new Firemin to be easy to use, we realized that some users still do not know how to use Firemin efficiently. In this article, I show how to select your preferred browser and use Firemin to stop those pesky memory leaks. I will be using Google Chrome as an example, but Firemin can be used with literally any executable.
To start, if you have not done so, install Firemin and open it by double clicking on the tray icon, or right-clicking on the tray icon and choosing
Select your browser
Firemin will work with any browser, in fact, it will work with any program. For example, to configure it for Firefox; on the main Firemin screen, press the Browse button and navigate to the Firefox directory (normally
C:\Program Files\Mozilla Firefox) and select the
Firefox.exe executable. Press the
Save button to store the setting.
Still on the main screen; set Firemin to
Reduce memory every 500 milliseconds. Although 1000 is the default here, we found that sometimes a lower setting yield better results. Play around with this setting to find your ideal configuration.
Only reduce memory if usage over x setting allows you to allocate a certain amount of memory to your browser. If you are experiencing issues with YouTube audio clipping or your browser seems sluggish, set this to 80MB or higher.
The extended processes feature allows you to specify additional executables to optimize. On the main screen, press the
Extended Processes button to open the Preferences window.
If you are experiencing the YouTube audio clipping issue while optimizing Firefox, try removing the
plugin-container.exe executable from the list. Remember to press the
Save button to store extended processes.
Other settings worth mentioning are the
Start Chrome when Firemin starts and
Start Firemin when Windows starts. We do not recommend using these settings together unless you want your browser to also start when Windows starts.
The first mentioned option is useful for when you would like to start Firemin from a shortcut and have your browser automatically open with it. This way you can automatically optimize your browser when opening it.
Please read before downloading Firemin!
If your Browser or Antivirus program warns you about possible malware, do not worry, Firemin is 100% clean. Click on the VirusTotal link next to each download to view the online malware scan before downloading. Because Firemin uses low-level commands to perform certain functions some overeager malware detection engines will flag it as malicious, but this does not mean it is. Read more here
