Firefox Memory Leak Fix
If there was ever a reason I felt like ditching Firefox, it was because of the annoying memory leaks. It just seemed to gobble up loads of memory for no real reason. Fusion94 has two fixes. Here is a snip of one that worked for me:
1) Type about:config into the location bar and press enter
2) Right click any line to bring up a sub-menu
3) Choose “new”>“integer”
4) paste this into the dialogue that appears: browser.cache.memory.capacity
5) Next click Okay
6) Specify the amount in kb (about 60000 should do) in the next dialogue that appears
7) Restart Firefox and happy surfing.
Update: Sam and Mike wrote in to say this method is outdated and doesn’t really work anymore. Thanks!
Update: Windows users can try this


This fix does not solve the problem on my Windows XP system (FireFox 1.0.6). Set memory.capacity to 60000, current usage reported at 85317.
Simple reason: The memory usage in RAM is both the max cache and about 10-25MB of RAM for the core application. This means that with 60MB cache maximum, it will use between 70 and 95MB of memory, so you are within the correct limits.
I tried this, but it isn’t working either. I am riding at 132MB, with 60000 setting mentioned in this fix.
So Erasmus’ logic is faulty.
