System Mac OSX 10.8.5 - Firefox version 25.0: I deleted Adobe Flasch Player to use the Add-On "YouTubeFlash to HTML5 2.9" - to watch Youtube-Videos, but it doesn't work. Any ideas?

If you use extensions (Firefox/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions aren't blocking content.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.
