Our user testing for a WebGL app we are building has shown that users who had a Beta version of Firefox installed and then upgraded to the stable release of Firefox 4 do not have WebGL enabled by default.  

Reproducible: Always

Steps to Reproduce:
1.Install Beta version of Firefox 4
2.Upgrade to stable version (NOT fresh install)
3.Attempt to view WebGL content (fail, check settings in about:config)



It would be nice if WebGL were enabled by default.

What graphic cards are these users using? Do they have the latest drivers for the graphic card? My understanding is that certain old drivers were blocked for the final release.

Better, type in "about:support" in a tab and scroll down to the "Graphics" section. Copy the results there and paste them here in a comment.

In addition to the Graphics section I would also have a look at the 'preferences' section, as I'm afraid it could have something with the gfx.blacklist prefs. It may be simplest to just 'copy to clipboard' the about:support page and attach it here.

Thanks for the quick response-

Here are my Preferences and Graphics sections:

We have 9 machines that are identical (maybe slightly diff drivers) and this issue has come up on more than one, upgrading from Beta to Stable 4.

Meh, almost certainly a dupe of bug 653102. The user in comment 4 _is_ getting WebGL, so one can't conclude anything from it.

(For a while I considered this could be a real bug with say conflicting D3DX DLLs but if that were the case, comment 4 wouldn't show WebGL correctly initialized in about:support).
