Fix Firefox Memory Leak

Does Firefox regularly use over 1 GB of memory on your Windows 7 64-bit computer? You’ll notice slow text entry forms and delayed clicks. If this is driving you nuts, let me share a nice tidbit that I ran across a forum:

In your browser address bar type “about:config”. Scroll down to the following:

javascript.options.mem.max: Its default value is -1, what I guess means automatic or unlimited. After some testing, I decided it's good to modify it to 50000, a value that appears to be in KBytes. Feel free to raise it to a proper value for you.

Close and reopen Firefox and your memory should be hovering around 350 MB now.
