Please file a bug with the contents of about:memory if you find situations in which Firefox uses much more memory than alternative browsers; Firefox is very serious about memory usage these days. You can cc me on the bug if you like to make sure it gets to the right people.
Thanks for the tip; I hadn't heard of about:memory before.
Is there a sane way to report bugs these days? I'm happy to do things like describing a useful test case or attaching a screenshot of about:memory, but I've spent too many half-hours trying and ultimately failed to report useful information via Bugzilla to ever go near it again. It's like a case study of how to do every possible thing wrong in usability terms. :-(
I know the interface got upgraded recently, and I've heard good things about the new upgrade—although I don't actually work with Bugzilla on a daily basis, so I don't have first hand experience. Anyhow, you might want to try the new version and see whether it works better for you.
