Unable to see any youtube video with 4.5

I did remove and block the cookies from YouTube... though I am unsure whether I had to redo that after the distribution's update.

Have you tried updating your browser addon "Flashvideo Replacer" with the new version? http://www.webgapps.org/addons/flashvideoreplacer/249-flashvideoreplacer-2-1-2-firefox or here: http://trisquel.info/en/browser/addons/flashvideoreplacer

It worked for me after I installed it.

Yeah update the flashvideoreplacer addon. Youtube changed how their URL detection worked a few days ago so the addon just updated as well to compensate.

The new version of the add-on solved the problem :). Thanks guys!

Ruben should update the version of FlashVideoReplacer in our repos to the new one.

You could also try the following:

Quoting AndrewT:

...then open its (FlashVideoReplacer) preferences window. Change Replace Method to Embedded, change Quality to Medium or Low, and change Plugin/Mimetype to WMP (application/x-mplayer2). Then embedded Totem will work, with a few disadvantages (no skipping ahead in the video, no replays, video has to be in fullscreen mode to view its length).

Hi, I also have this problem. The link for flashvideoreplacer no longer works. Videos no longer play. None of the mentioned settings make any difference.

update the version of fvr via the repo or go get it from http://www.webgapps.org/addons/flashvideoreplacer under "Download".

If that doesn't fix the problem try to set the Plugin/Mime-Type of fvr to "wmv".

I installed Slaine last night and did a repo update and it worked fine.

If you have both VLC and Totem Add Ons enabled, disable one as running both won't make neither the Linterna Magica nor Flash video Replacer work.
