Since i’ve updated to 11.3 one of this process take until 80% for CPU usage when a flash is on in FF!
Any help?

Have you upgraded to latest version, 80% usage is surprise for me, try resetting Firefox and uninstall and reinstall flash again.

No, it’s not fixed if you run Vista 64 bit Premium. Youtube, or any video or game that uses Flash Player does not load with Firefox.

When trying to play youtube videos, the sound is still awful…crackling , static, echo effect and more…impossible in firefox….yet perfect playback in internet explorer…how does this stuff happen, with supposedly the best tech minds around, at the controls?

I came across your article trying to find if someone else has the same problem.

After installing this new update, my cpu will go up to 100% and stall (70-80% for firefox alone). I was, as usual,opening 5-8 tabs and just 1-3 sites known to me has flash advertising or banner on the site.

Firefox 12 & 13 works OK with flash 11.3 when you use the plugin from Google Chrome – gcswf32.dll instead the plugin made for Firefox (NPSWF32.dll).

Sorry I didn’t get you, can’t understand. Can you elaborate a bit.

In my case I use portable Firefox downloaded at
I just extract the flash plugin (gcswf32.dll) from Google Chrome (also portable version).
Then I rename it into NPSWF32.dll and place it in the \Data\plugins folder of Firefox (portable).
In this way the flash works for me fine – no crashing of Firefox.
(Portable Google Chrome comes with the flash plugin in it, while Portable Firefox do not.)
