Yes, it makes no difference.

Will do. Currently they are all set to "ask to activate".

Follwed the link and updated the drivers for my Radeon. Still crashes.

bp-aa2ef469-c849-4589-8716-2806c2160729 29-7-2016 20:09 I see there are now 3 "missing symbol" errors (again in atidxx32.dll (see the new version), but now also in atidxx32.dll and msmpeg2vdec.dll), where there was just 1 before. Not really an improvement I guess?

Unfortunately the new drivers also makes my computer very slow (startup time is now 5 minutes) and most applications including FF became sluggish.

I noticed that when I logged in as adifferent user FF did not crash. Then I remembered that about 1 year ago I had a problem with FF: https://support.mozilla.org/en-US/questions/1030862

I fixed that by setting layers.offmainthreadcomposition.enabled to false in about:config.

The FF profile of the other user did not have this modification.

I reverted layers.offmainthreadcomposition.enabled to true and in a short test I could not provoke the crash (did the same things as in the first post of this thread).

I will report after a few more day wether the crash really has gone.

Mind you: even if this does resolve my issue, IMO it still is a bug.

Bart

Good luck.

It's been a few days since I reverted layers.offmainthreadcomposition.enabled to true. I have seen no more crashes, so this seems a goor workaround for this issue.

Good to hear. Well done.
