Comment 1 Vitor Gomes 2015-08-25 15:57:23 UTC
When crashed using dbg, firefox failed to produce a crash report.
Crash reproduced in equivalent conditions, report here:

Comment 2 Martin Stransky 2015-08-26 10:08:55 UTC
Yes, I see that, it's cased by broken (null) cairo context.

Comment 3 Martin Stransky 2015-08-26 10:24:05 UTC
Can you please:

- check you have OMTC disabled (in about:config layers.offmainthreadcomposition.enabled should be false)
- test latest nightly build from mozilla (

Comment 4 Martin Stransky 2015-08-26 10:31:47 UTC
Do you see that only on gmail or does it crash on other sites too?

Comment 5 Vitor Gomes 2015-08-26 11:29:51 UTC
OTMC is off, as default. Did test with it enabled, with the same results.

Haven't seen crashes anywhere other than on gmail and facebook, as described.
Will try the latest nightly on those two sites and report back.

Comment 6 Vitor Gomes 2015-08-26 11:54:16 UTC
Nightly build seems to work good, no crashes in either situations.

Comment 7 Martin Stransky 2015-08-26 12:03:34 UTC
Looks like you hit - which is fixed in Firefox 41. I'll try to include the patch in our next update.

Comment 8 Martin Stransky 2015-08-26 12:25:02 UTC
Added the upstream patch to firefox-40.0-10 - will be available here:

Comment 9 Vitor Gomes 2015-08-26 16:07:57 UTC
Started to see crashes in some other sites, navigating for example. 
Should be related to the same bug, again Nightly build works good.

Comment 10 Olivier Crête 2015-08-26 18:59:30 UTC
*** Bug 1257297 has been marked as a duplicate of this bug. ***

Comment 11 Martin Stransky 2015-08-26 19:49:56 UTC
Can you please test those builds?

Comment 12 Vitor Gomes 2015-08-27 11:08:30 UTC
As with the nightly build, no crashes in any of the previous places.
One caveat though: on facebook, the right hand column seems to be missing the facebook chat friend list (, p.ex), and on fB chat tabs some (not all, strangely) user profile photos are "broken", the "torn document" icon appears instead.

These I can live with though. Thanks for the help!

Comment 13 Vitor Gomes 2015-08-27 11:10:18 UTC
Forgot to mention, that's with the 40.0-10 build.
