Firefox crashes on WebGL and Canvas pages (radeonsi_dri.so)
Using Firefox 31 on Xubuntu, visiting pages which display WebGL or Canvas content produces very frequent crashes, with the cause apparently being a segfault when interacting with the radeon driver. One example that always produces a crash for me is the "Ninja Impact" example from the Phaser.js library. Other ones vary, but usually after viewing one or two WebGL applications (for example, the three.js demos), I get a crash.
Tried the nightly build - same result. No crashes on WebKit browsers.
See example crash here: https://crash-stats.mozilla.com/report/index/0deedd68-e6bc-4c52-b8f6-745962140730

That looks like a problem with the display driver (radeonsi_dri.so).
Is there an update available or can you try another (generic) display driver?
Are there any error messages on the troubleshooting information page in the Graphics section?

You can try to disable hardware acceleration in Firefox.
- Edit > Preferences > Advanced > General > Browsing: "Use hardware acceleration when available"
You need close and restart Firefox after toggling this setting.
Disabling hardware acceleration didn't change anything. If this really were a driver problem, I would expect to see the same behavior in all browsers - WebKit based ones don't crash for me (and also have better WebGL performance).
