Firefox stutters after some time spent browsing


(Firefox :: General, defect)

13 Branch
Windows 7





(Reporter: humpolec, Unassigned)


After spending several hours browsing websites, Firefox starts to freeze every few seconds - scrolling and dynamic website elements stop, Flash video freezes. The memory usage also skyrockets (highest I've seen is 1.5 GB in W7 64-bit).

Restarting the browser seems to fix the problem, but it often takes more than half a minute for Firefox to shut down.

The problem has persisted at least a few versions back, and appeared both in Windows 7 32-bit and 64-bit.
If you browse around with the Flash Plugin disabled (Addon Manager/Plugin Panel) does it make a Difference?

Can you attach a about:memory Text Output to this Report with High Memory Usage?
