How To Fix Memory Leaks In Firefox In Windows

Posted Mar 11, 2009

I love to use many tabs at once when surfing the Internet.  Its purely a habit.  But for some reason Firefox tends to freeze up on me when I open up many windows at once.  Sometimes Firefox would take up about 800,000 K of memory on Windows for me.  This would cause all of my other applications to slow down until I hit Ctrl+Alt+Del and killed the process for Firefox.

Finally I just became frustrated by it and searched for a fix on Google.  Here is a solution I found that seems to be working pretty good for me.

1. Open Firefox and type in about:config into address bar and then press Enter.
2. Right Click anyway of the page and select New -> Boolean.
3. In the box that pops up, we create name as changemode:on_minimize and press Enter.
4. Lastly select True and then press Enter.
5. Restart Firefox.

I opened up about 16-20 tabs at once after applying this method and now it seems to be taking up less memory than Tweetdeck.  I don’t know exactly what it is doing to keep the memory down on Firefox now, but as long as its functional, I’m not going to question it.

Thanks to Windowsforum page for the fix.
