However, It is our opinion that Windows does not clean out memory as often as we would like it to. You could argue that this makes Firemin unnecessary, and you would be spot on. Windows will also periodically scan running processes and tell them to release their unused memory. All I did was tweak our Memory Booster a little and applied it to Firefox and this solved the memory leak issues. Simply put, Firemin will attempt to eliminate Firefox memory leaks and decrease the amount of memory Firefox uses. 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.

It’s quite normal for Firefox to be sucking up over 250 MB of memory right off the bat. Because of this Firefox was using over 3 GB of memory after a few days. Programs on my computer can stay open and run for days or even weeks, and Firefox is no exception. 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.

Firemin is a small utility to reduce the amount of memory Firefox or other browsers use.
