Mozilla/5.0 (Windows NT 5.1; rv:6.0) Gecko/20100101 Firefox/6.0 Firefox 6.0b4 crashes sometimes when multiple pages that uses WebGL are loaded in the same window.

The signature is very reminiscent of bug 646825. But if it were a duplicate, it would be fixed in Firefox 6.
This is ANGLE bug 139: http://code.google.com/p/angleproject/issues/detail?id=139 ANGLE r712 (and perhaps 713) should fix it.
We want to take this in Firefox 6.
Created attachment 550184 [details] [diff] [review] ANGLE r712 This is ANGLE r712, r=upstream.
Comment on attachment 550184 [details] [diff] [review] ANGLE r712 Approved for releases/mozilla-aurora and mozilla-beta. Please land asap
Landed on central, aurora, beta. http://hg.mozilla.org/mozilla-central/rev/d6301744afa9 http://hg.mozilla.org/releases/mozilla-aurora/rev/e442db72f342 http://hg.mozilla.org/releases/mozilla-beta/rev/99e2010c484c
Mozilla/5.0 (Windows NT 5.1; rv:6.0) Gecko/20100101 Firefox/6.0 I got another crash on Firefox 6 beta 5 after unlocking my computer. STR: 1. I loaded the two pages from the description. 2.

Oops. Trying to reproduce now.
If this is the issue r712 is patching then it's a regression from bug 646825 (both patches from angle bug 139). If r712 doesn't fix this crash then it's something else entirely.
Results from trying to reproduce: * on Win7, I can't reproduce any crash * on WinXP, I could reproduce one crash with these STR, but it was a different one altogether: bug 676918
So, sounds like we are ok here for Fx6. Adding the screen locking into the steps to reproduce makes this a lot less common (looks like 3 total crashes across all versions over the last week).
I see ANGLE r686 in about:support for 6.0b5/20110804030150. Is something missing in the ANGLE r712 patch?
We're at ANGLE r686, plus some patches including r702 and r712, but we don't have all the ANGLE revisions in between, so I'd still call this 'ANGLE r686 plus patches'. The README.Mozilla file is indeed outdated, it says r653, should say r686.
Setting status-firefox6 and status-firefox7 to reflect the aurora and beta checkins in comment 6 (otherwise this bug appears on the "approved but not landed" triage list).
This appears to have been fixed. Please reopen if you're still hitting this crash.
