Firefox Memory Leak

How do I go about tracking this down?

I'm sure it's a memory leak because it happens noticeable after leaving the computer idle for a while (for example I'll leave it alone at 2.2gb with Firefox taking up most of that, and when I come back it's u near 3.4+ (max 3.69gb) and nearly totally unresponsive).

Versions are from the arch repositories.

Firefox (add-ons: session manager, ad-block plus)

Re: Firefox Memory Leak

First, 'latest patch' is not helpful.  Are you running versions from the Arch repositories, are are you patching them yourself.  If you are running repository versions, tell us specifically what they are.
What video driver are you using?
What browser extensions are you running?
How do you know there is a memory leak? How do you know it is not just the memory footprint legitimately increasing?

Which logs should I be looking at?

Re: Firefox Memory Leak

I'm also having this problem... after a long time idle and if firefox is open, it is very likely the system will use a huge amount of swap memory, thus slowing everything down... I'm pretty sure it's firefox and/or the flash-plugin, because I then log in in a VT and killall -9 firefox makes my system back on the tracks....
