How to use Firemin

By | December 17, 2017

Even though I created the new Firemin to be easy to use, I 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 Pale Moon 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 Open Firemin.

Select your Browser

On the main Firemin main screen, press the Browse button and navigate to the Pale Moon directory (normally C:\Program Files\Pale Moon) and select the palemoon.exe executable. Press the Save button to store the setting.

Configuring Firemin

Still on the main screen; set Firemin to Reduce memory every 500 milliseconds. Although 300 is the default here, I found that sometimes a higher setting yield better results. Play around with this setting to find your ideal configuration.

The 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.

Extended processes

The extended processes feature allows you to specify additional executables for Firemin to optimize. On the main Firemin screen, press the Extended Processes button to open the Extended Processes window.

If you are experiencing the YouTube audio clipping issue, try removing the plugin-container.exe executable from the list. Remember to press the Save button to store extended processes.

Other Options

Other settings worth mentioning is the Start Pale Moon when Firemin starts and Start Firemin when Windows starts. I do not recomment 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.


I hope, after reading this article, you know how to use Firemin. However, please leave a comment if you have any questions or something is still unclear.

    You say “Firemin can be used with literally any executable.”
    You mean any browser executable or all executable, Word 2016 executable for example?

    I cannot thank you enough for this program.

    I use Tab Groups with FireFox and have noticed times when FireFox is using over 1 GB of memory.

    Each wee, I encounter times when my PC has become unresponsive for many seconds at a time, as a result.

    Firemin has stopped the freezes completely!

    You have my deepest gratitude, and the donation I just Made. 🙂

    Hey Derick… Firemin works spectacularly! It’s like CRAZY yeah… Gone from 2.5 GB of RAM (admittedly I have 70 plus tabs open – because I do actually need to), to a measly 30 MB. Like I said before… That’s insane. Thank you so much!! I’m on Windows 10 64 Bit (Home Edition) and using FF 51.0.1 32 Bit (Roboform doesn’t like the 64 version so much). Thanks again 😉

    Is it possible to rise the upper limit for ‘Only reduce memory if usage over x’ at least to 200-300 for example?
    I’d like to control my browser’s appetite only from 250-300Mb used. Please, make it possible!
