One of the things that turn people off from Firefox is it’s tendency to be a resource hog. There are several ways to address this. One is not to max out Firefox – just keepin. Another way is to limit the number of add-ons activated at a given time. Or you can do these RAM tweaks.

Another surefire way to police this tendency is by purging your cache. This can be easily done by pressing Ctrl + Shift + Del that loads up the Clear Private Data window, checking Cache and clear the data. However, one drawback to this is that it clears both Firefox’s disk and memory cache. If disk space isn’t really an issue, it’s the memory cache that you’d want to purge.

Cache Satus is a great add-on that helps you monitor your cache usage by displaying the information in your status bar (much like accessing the about:cache page). What makes it even handier is a feature that allows you to purge your RAM or disk cache or both when you think either one’s hogging too much resource.

You can even set the maximum cache sizes for both RAM and disk. And as for the latest update, it also features automatic cache clearing when it reaches a certain percentage that you set.
