Xlib_skip_argb_visuals=1

[Frikazoid]

I found many suggestion about this string XLIB_SKIP_ARGB_VISUALS=1 as a solution to firefox crashes with flash contents.

I put that inside the /usr/bin/firefox script... but now I cannot use compiz anymore

If i run compiz command it says no xgl, but I always used it perfectly before that.
thank you

I tried to reinstall nvidia

You don't need Xgl on a nvidia chip.
Remove it:

sudo apt-get remove xserver-xgl

Then restart X and post the output of http://ubuntuforums.org/showthread.php?t=799070
