what version of flash player do you have?
Filename libflashplayer.so Plugin Version: Plugin Description: Shockwave Flash 10.0 r45
Does it never restore?
No! It simply hangs. No button are click-able, nor link, nor tab, but the "X" close button. When looking on the System Activity, the FF process is working. Sympli, it does not respond to any click or keyboard command.
same here. i'm using namoroka version 3.6.4~hg20100410r34032+nobinonly-0ubuntu1~umd1~karmic on amd64 with just updated flash 10.0 r45 as said, it simply hangs: cpu at 0%, it's just locked
(In reply to comment #5) I've also tried 3.7 version "minefield", but same behaviour
just discovered the problem is related to the latest OOPP (out of process plugin) entering about:config and modifying the key dom.ipc.plugins.enabled.libflashplayer.so to false, fixes the problem
Great job! This solves the problem for me. Thanks! The issue is now marked as solved although, I have a question: could you please tell what the record dom.ipc.plugins.enabled.libflashplayer.so relates to? Thanks again.
that is oopp, so this is still a bug.
I have filed a bug (581302) which might be related to this one. Also the following may be connected: 558555, 580497, 579597, 581302. My observations on my low-end hardware PCs are that Flash content web pages cause high CPU usage. This effect was quite dramatically increased after the landing of 'Retained Layers' on Trunk. The effect is further compounded if OOPP is activated for the Flash plugin. Several bugs have attributed the cause of 'slow scrolling' and 'hanging' to OOPP implementation, the flash plugin itself or 'retained layers' but in my experience they seem to be closely related.
See also: https://bugzilla.mozilla.org/show_bug.cgi?id=713367#c3 I've been experiencing choppy performance on OS X nightly, particularly with flash content.
Does it still exist with Firefox 11+ and Flash Player 22.214.171.124+ ? Try it with en-/disabled Flash Player hardware acceleration please. Check/update your graphics driver and OS too.
