Firemin 

One of the biggest 'improvements' that Mozilla claims is the Firefox memory usage, in particular, the vanquishing of memory leaks. If you thought it was too good to be true you were right. Firefox still uses a lot of memory - way too much memory for a web browser.

We like keeping our browser windows open for a few days 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 100MB of memory right off the bat. In a memory leak you'll see the memory usage keep increasing the longer the browser is open/in-use and this is exactly what happens with Firefox.

Rather than complain about it, we decided to fix it. Enter Firemin; simply put, it will eliminate all memory leaks in Firefox. All we did was tweaked our memory booster core a little and applied it to Firefox (including most extensions) and all the memory leaks was gone. To use Firemin; you will need to unzip Firemin.zip, double click on Firemin.exe and let it babysit Firefox. If you expected it to be more complicated, we are truly sorry to disappoint you.
