Firemin 6.2.3.5060

Firemin control the amount of memory Firefox uses. Although Firefox memory usage improved a little over the last few years, it still uses a lot of memory

Windows will also periodically scan running processes and tell them to release their unused memory.

Windows does not clean out memory as often , 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.
