The crash in comment 1 is with Catalyst 10.3 (atidxx32.dll 8.17.10.261)

Here are a couple recent examples: https://crash-stats.mozilla.com/report/index/5719b764-a85a-4080-9aa2-19fbc2111102 (driver version 8.741.0.0) https://crash-stats.mozilla.com/report/index/c1826a63-7451-45b1-a242-7e0ae2111116 (driver version 8.902.0.0) Note that 8.902 = Catalyst 11.10, which is only a few weeks old, so this isn't just happening in old drivers.

I'm closing this bug as incomplete. There are a couple of reports on the latest release with pretty old AMD hardware/drivers. If someone has some leads and wants to try fixing this then please reopen.
