How to prevent firefox from eating up too much memory?

When firefox is running on my comp for a long time, it eats so much memory. How to prevent that or at least stop it when it’s happening?

yeah bro…..i checked it right now…..59MB
I dont think there is a remedy…..may be not using tabbed browsing(browsing 1 thing at a time)
I have 1GB RAM….so it actually doesnt matter
Firefox dynamically assigns memory cache usage. If you wanna specify the memory cache capacity yourself, do it by first typing ‘about:config’ (without quotes) in the Firefox address bar and add a new preference(right click on the about:config page and select new-integer) and name it as browser.cache.memory.capacity and specifiy the integer value in KB …however this should depend on the amount of physical RAM you got.If you’ve got 256 MB of ram, this should be around 4096. For 512 MB RAM this should be between 6500 and 8000. So experiment with the memory cache capacity and see what works best for you.
Not to mention, the changes will be reflected and seen when u type ‘about:cache?device=memory’ (without quotes) in address bar. Here you can see the max storage size, storage in use..etc…
Also, add another preference(if you wish) , right click on about:config page and select new->boolean. type in config.trim_on_minimize as the preference name and set it as ‘true’ . This tweak is for lowering down firefox memory usage when you minimize it.
Another memory tweak is to reduce memory usage by affecting the back and forward browsing, read about this from here
Also if you use too many extensions , disable some of them temporarily. That’ll reduce some of the memory usage. If you don’t know already, disable them by clicking Tools-> Add-ons-> Extensions->Here select the addon which you don’t require all the time and hit ‘disable’. The addons themselves can pose a memory leak issue. Also make sure you’re using the latest stable version of firefox. The article about problematic and memory hogging extensions is here:
