More Information
What kind of videos are you referring to?
Is a Flash player used to play the videos?
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

You can check for problems caused by recent Flash updates and try these:
- disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
- disable protected mode in Flash 11.3 and later
- disable hardware acceleration in the Flash plugin
