Hey guys. This is occurring with the recent trunk hourly builds (1414677136 specifically). Having a Youtube video running while quickly (repeatedly) clicking on the Firefox taskbar icon causes the following crash. I am able to reproduce this on a clean profile. https://crash-stats.mozilla.com/report/index/7e4a2781-86ab-4014-94ef-107c92141030 https://crash-stats.mozilla.com/report/index/623cd4b7-931d-4dfe-a300-77c382141030 https://crash-stats.mozilla.com/report/index/58d1f103-8aa8-4358-8b36-fe9d22141030 https://crash-stats.mozilla.com/report/index/f3606491-ed2b-4651-ba91-330962141030 https://crash-stats.mozilla.com/report/index/fada932f-42ea-4f8a-91c1-01a5c2141030 I am unable to provide any further information at this time. It only seems to happen in the instance as given above. If there is any information I can provide to help track it down, just let me know.

Do you use a local compiled build ? All the crash reports are without symbols nd therefor not useable. This can only happen if you use a build that isn't compiled by the Mozilla build systems which send the debug symbols to the crash server or of there is some kind of issue in the crash server itself.

It was a hourly build from the following link: http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32/1414677136/ I needed to get the crash fix for another graphics bug I have been hitting (bug 1089364). I'll try it again with tomorrows nightly build to see if I can get a clear report that is complete with debug symbols.
