Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at if you are uncertain if they are bugs.

When you say watching Youtube videos in fullscreen, is it important that it be via Firefox3b5? A couple of other options are using the
package miro to download and watch (does fullscreen quite well), or just via youtube-dl and then watching via VLC.
Both miro and youtube-dl are in the ubuntu software repositories.

Ryadt, I am experiencing exactly the same problem as you. So apparently there is something wrong with our Flash or Firefox? Which Flash version do you have installed? Enter 'about:plugins' into firefox's location bar.

This is only a temporary solution, but it might be related to the permanent solution: while the youtubevideo is playing, right click on it and select flash settings. Even if it says that it is already allowed, hit the allowed box one time to reallow. Close your settings menu, and you then hit the full screen buttin. This will put the full screen up. However, you have to repeat this process every single time. So, its a glitch. This was done with Flash 9 installed.

I have the same problem, and use similar workaround than mrgnuopensourceman. I don't have to reenable, or change anything in Adobe Flash Player Settings, just to open the dialog and close it. After this I switch to fullscreen and it stays there until I exit fullscreen mode.

I do have the same problem with Firefox 3.0.1 and Adobe flash player 9 in the same way like Békipe, just opening then close the setting dialog fixes it.

I have installed Flash v10 and this seemed to fix the issue.

I have Ubuntu 8.10 upgraded and Firefox 3 04.
I have Flash v10 (according to flash in youtube) I still get the problem.
No full screen at all.
If I hit settings I only get the option to use 3d acceleration.
I have a ATI card in this pc and compizfusion running.

I used to have this problem in my dell-mini using custom hardy (with flash 9). I upgraded to flash 10 and i have now full screen.

Jonathan Sambrook, after 2 days of browsing and surfing as to find the solution, yours (quoted in the link) worked like a charm. Countless thanks. You n shalley303 saved my life for I was almost about to reinstall the system (a dark despair or so).

Can you help with this problem?
