When I load a WebGL website on Firefox 5 in my Ubuntu 11.04 system, I get a grey screen and a warning on the terminal like this:

[GLX] your GL driver is currently blocked. If you would like to bypass this, define the MOZ_GLX_IGNORE_BLACKLIST environment variable.

Acceleration works fine on Google Chrome. How can I enable back acceleration for Firefox?

I don't know why the driver is on the blacklist, but you can do what's suggested: try running MOZ_GLX_IGNORE_BLACKLIST=1 firefox.

If this works, you can modify the .desktop file /usr/share/applications/firefox.desktop and change the line

Exec=firefox %u`

to

Exec=env MOZ_GLX_IGNORE_BLACKLIST=1 firefox %u
