Constantly need to ctrl-0 or flash video stutters
For the last few weeks I have a problem when viewing Flash videos full screen- after a few seconds of working properly the screen pauses and then speeds up / surges to catch up then pauses again. Disabling hardware acceleration does nothing and pressing ctrl-0 (as per the help topic on flash videos) prevents the stuttering. Infact if I press ctrl-0 constantly it plays fine. Playing the same flash video via IE is no problems. There's no disk thrashing or high CPU / memory usage (accourding to task manager) when this happens. I've tried removing and re-installing Flash and also the same for Firefox. Any ideas? At the moment I'm using the "open in IE" add-in but it's a bit annoying....

Sorted! Going into safe-mode switched off all the extensions but the plug-ins were still working. I deleted Panda online security and Mindspark toolbar plug-ins (which I don't recall installing.... grrrrr) and it's all mended.... Thanks for the info.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
- https://support.mozilla.org/kb/Safe+Mode
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
