I can reproduce this using Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:15.0) Gecko/15.0 Firefox/15.0a1. STR: 1. Load maps.google.com and enable WebGL 2. Map out a set of directions 3. Go to street view and pan around I was able to crash following these steps but I crashed in other instances as well. You will find it is not that hard to crash on that site. https://crash-stats.mozilla.com/report/index/bp-7327e7fd-07d7-49e3-91d9-ced552120519
Appears very frequently and consistently. This bug is also very annoying. Recommend you change the importance to Blocker. Hope a fix is under way. I don't want this bug to last for more than a day or I'll really be disappointed. Thanks.
liyc_oliver, developers are on week end. Please use the stable version of Firefox you can download from http://www.mozilla.org/firefox
Pardon me, but for such a critical bug, there is definitely one developer in the whole world willing to sacrifice their weekend to fix it right? If I had enough coding experience, I would definitely sacrifice my weekend to fix it. Especially when so many f-words are coming out in the crash signatures comment tab. :#
Would be helpful to derive the exact changeset that caused this by using mozilla-inbound builds. Also, I believe that bug 756797 with its signatures is the same thing, probably all caused by a single thing that landed in the JS engine on Friday.
I'd expect it to come from <http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=9dab33fa5ff4&tochange=642d1a36702f>, so one of luke's patches seems likely.
Bug 755604 is also a possibility.
liyc_oliver: It does not take a lot of coding experience to compile Firefox from source code (almost none, in fact). If you can compile it from source code, you can run 'hg bisect'. Once you run hg bisect for a few hours, you will have identified the regressing changeset. Once the regressing changeset has been identified, the sheriff can consider backing it out, and the JS team will be able to focus on fixing the bug rather than hunting for the regressing changest.

This seems to be caused by bug 755604 indeed - sorry! A likely fix is in bug 756851. I'm re-building now to verify and will post an update afterwards.
The likely fix is now compiling on the try servers: https://tbpl.mozilla.org/?tree=Try&rev=786e061ae7f3
My testing confirms the fix and try server looks green so far. If anyone's interested, here are try builds containing the fix: http://firstname.lastname@example.org/
I cannot reproduce the crash using that build on my Mac following my STR in Comment 2.

Bug seems fixed in version 21/5/2012 Nightly. Great job guys!
This is indeed fixed by http://hg.mozilla.org/mozilla-central/rev/fb3036d9b9e6
