Firefox 3.0 Memory Consumption Greatly Improved

Last time I blogged about Firefox (2.x), I was complaining about how much memory it was sucking up. I have read about how many memory leaks were supposed to have been fixed in Firefox 3 but I had to see it to believe it. So after suffering again from low memory while running VMWare and Firefox (whose memory consumption regurarly climbs to 500MB) at the same time, I decided to upgrade and leave Firefox 2.0 for good.

Firefox Memory Usage Through the Roof

Firefox's memory usage has just gone nuts lately on my work machine, approaching 1 Gigabyte of RAM usage:

I have no idea what is causing it. The most likely culprit is either some javascript leak on a page I leave open all the time (like GMail for instance) or a leaky extension/add-on. Here are the add-ons that I use:

My suspicion is that it might be Fasterfox that is causing the problem. I will disable it and see what happens over the next few days.


Firefox/Opera Shootout

I've been getting really pissed off lately at how much memory Firefox is using up. I decided to give Opera a try. I opened up the exact same tabs in Opera (about 10 of them) and I got about the same memory consumption. I disabled all the Firefox extensions except for the one (because last time I disabled it and re-enabled it, it totally screwed up the bookmarks menu, and I had to create a new profile from scratch to get it back to normal).
