[Bug 1064474] Re: Firefox high cpu usage

[Neil Burgin]

not sure if this is the same bug or if I should report a new one, but I
get gradually increasing CPU usage the longer I have the program open.
At first I thought it was from having too many tabs open but even after
closing all of them, it was still sucking a massive amount of CPU. Then
I close and restart firefox and it's fine. I'm not sure if this is an
upstream programmer error on the part of Mozilla or if it's just
firefox's ubuntu packager using far too aggressive optimization flags
that screwed something up subtly. (about:buildconfig reveals a startling
amount of optimization flags, including that it used -Os instead of -O2)

Mind you, Firefox's performance doesn't slow down any. I can only detect
that it's happening by monitoring my CPU usage.

It's a very subtle problem. It only appears after a long session in
which firefox has not been closed and restarted.
