After the upgrade to 16.0.1 some Youtube videos just won't play. They work perfectly in Chrome. A couple examples: http://www.youtube.com/watch?v=rQpldNJXuP0 http://www.youtube.com/watch?v=-e-BRki7gwU Most of the videos works perfectly, so i can't tell what the problem is.

I tried that as the first thing, but it didn't work at all. Anyway, i solved the problem in the meantime by uninstalling Firefox and reinstalling it. Please note that i had to make a CLEAN installation, and by "clean" i mean that i had to remove the settings as well. First i tried to reinstall it but i kept the settings (Firefox asks you if you want to keep them when you uninstall) and it didn't work. So i just saved the bookmarks and uninstalled everything else. The subsequent reinstallation solved the issue.

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

  • Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Tools > Options > Privacy > Cookies: "Show Cookies"

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.
