Firefox is a PIG on memory

I would consider busting out a memory profiler, but generally, I let 
other people clean up the messes they make. I had a job where I had to 
fix a leak in someone elses code, and that was horrible to say the 
least. As per other peoples posts it is a known problem, hopefully it 
will be fixed in upcoming versions.

While on the subject though, what are some good memory profilers for 
linux (my only experience was win32)??
