Since upgrading to Firefox 3 a few months ago, I’ve been pretty impressed by the performance of Mozilla’s latest browser. Generally, page loading times seem slightly quicker, although several of my add-ons are still not supported by it, which is something you have to unfortunately resign yourself to every time you upgrade Firefox.
However, one major problem that I was experiencing was a severe memory leak when Firefox would suddenly hog my RAM and CPU for about a minute causing the browser to hang, or even crash. Although memory leaks have been an ongoing problem with Firefox, this was far more serious and persistent that usual. The simple solution, it seems, was to sign out of the Gchat module in Gmail. Simply by being signed in, Gchat could suddenly conflict with Firefox for no apparent reason. A quick Google search revealed that I wasn’t alone either with desperate users flocking to Mozilla’s forum to find a solution.
