Hi! I have changed from chrome back to firefox because some problems related to html5 and flash videos. But something curious happens. On chrome I have accelerated video rendering but software decoding. On firefox i can have both accelerated but when i right click a youtube video, the whole frame while the right click menu is open are dropped... i can't see way that would happen I've a pretty fast computer, so it's not because of a slow computer.. And on chrome the video stills plays without dropped frames with the right click menu, but the video decoding is made via software.

Try the Firefox Safe Mode to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open the Firefox 4.0+ Safe Mode by holding the Shift key when you use the Firefox desktop or Start menu shortcut.
  • Or use the Help menu item and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Don't select anything right now, just use "'Start in Safe Mode" To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again. If it is good in the Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one.

Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Hi! Thanks for the time spent trying to help me. I have tried to open Firefox in safe mode already, and it did not work. I have now tried to disable flash hardware acceleration, and i can confirm that it isn't related to the hardware video decoding, it happens with software decoding too. Thanks, Isaac
