[ubuntu] Firefox crash ONLY when clicking fullscreen youtube

[Pappy1911]

Don't know...just thought there may be a relationship here....

Thanks for the idea, the problem has me baffled but im sure someone else must have had the same problem.

I have Jaunty 9.04 and I have the exact same problem. Watching youtube videos in default mode is no problem. When I click on "full screen" it simply closes firefox without any prompts.

I spoke to the ubuntu irc channel people and one of them recommended it might be the flash plug in which enable videos to be watched in firefox. Basically it might be a problem with Adobe Flash Player.

Solved: load the flash plugin before firefox or swiftfox. It's a NVidia driver issue. (edit: not only... ATI users seem to benefit from this too).
Easiest fix: modify the startup script of your browser, e.g. in case of Minefield (firefox-3.6):

gksudo gedit /usr/lib/firefox-3.6a1pre/firefox.sh

Find your browser script in the same area, somewhere in /usr/lib/yourbrowser; (edit: other possible locations are like /usr/local/lib/firefox-3.5/firefox or for install with ubuntuzilla it is /opt/firefox/firefox; using a run-mozilla.sh file if that is available also seems to work);
then add as 2nd (NOT 1st) line:

export LD_PRELOAD=/usr/lib/libGL.so.1

I'm not sure if this will keep working after an update of the browser (then do it again).

This doesn't seem to work for 64-bit; you'll need to rightclick flash video and disable hardware acceleration (thx Garyhans).

If you now have the problem that when you press full screen in youtube you see your compiz animation for opening a window, it very briefly shows video full screen (less than a second) and then the full screen window closes, then do the following (thx Danbo19): in compiz config settings manager go to Effects > Animation > Open Animation > Add and add "!(name=firefox)" (without "", but with !).

SCRIPT OPTION
###########
If this doesn't work or you don't like this solution try the following:
I couldn't get it done in a launcher command but I used the script option (copypaste in gedit and save):

#!/bin/sh
## replace firefox-3.6 with what you use, e.g. firefox, firefox-3.5, swiftfox
LD_PRELOAD=/usr/lib/libGL.so.1 firefox-3.6

or when you run from an extracted tarball:

#!/bin/sh
export LD_PRELOAD=/usr/lib/libGL.so.1
/path/to/firefox

Now to run your browser make a launcher with as a command:
sh /path/to/script

Adding:

export LD_PRELOAD=/usr/lib/libGL.so.1

To the second line of /usr/lib/firefox-3.5/firefox.sh worked perfectly with the latest release candidate of Firefox! A big thank you! I was sick of using the Compiz enhanced zoom feature as a work around. Again, thanks!

Finally! Thanks VCoolio.

(BTW, I have ATI, not nVidia, but still had this problem until now)

[infoaddicted]

Thanks VCoolio! That worked for me!

Thanks a lot VCoolio, its unbeleivable that Mozilla didn't pick this HUGE bug up during development, come on Mozilla !! people use Firefox on other platforms other than Windows !!

I don't have /usr/lib/firefox-3.5/firefox.sh

I have compiled Firefox and it was installed at /usr/local/lib/firefox-3.5 and there is no firefox.sh there. The only similar file available is plain firefox, but it doesn't work. Do you how do I find it or if this can be done another way?

[VCoolio]

search in /usr/bin or try the script option I gave as alternative.
