Comment 36 for bug 875538

So, I've done a bit of research today, and this seems to be a combination of flash, firefox, and the nvidia binary driver.

- All versions of flash 10 work properly
- flash 11 with firefox 8 from the team PPA works properly

flash 11.1.102.55 with ff 3.6.3 - works
flash 11.1.102.55 with ff 3.6.6 - works
flash 11.1.102.55 with ff 3.6.8 - works
flash 11.1.102.55 with ff 3.6.9 - broken
flash 11.1.102.55 with ff 3.6.11 - broken
flash 11.1.102.55 with ff 3.6.21 - broken
flash 11.1.102.55 with ff 3.6.24 - broken

It seems something was introduced in firefox 3.6 that is causing the hang issues with flash 11.
