|I've been noticing recently that Firefox takes up several hundred MBs in the Windows Task Manager after I've opened and closed a bunch of tabs. This is a bad thing. So I looked it up.
This site says to go to "about:config", create a new integer called "browser.cache.memory.capacity", and set it equal to "16384". The problem is that this did nothing. Apparently, it only works in older versions of Firefox.
This site says to go to "about:config", create a new boolean value called "config.trim_on_minimize", and set it equal to "true". Whenever you minimize Firefox, the memory usage will go down considerably. Mozilla knows about the problem and agrees with this solution. I tried it and it worked. #technology
