STR: 1. Launched Firefox 2. Beside the already pinned tabs (9 pinned tabs) opened 9 more tabs (CNN, BBC, Facebook, NYTimes, about:crashes and 4 crash reports from Soccoro) 3. Crashed Nightly twice using the crash me now add-on (https://addons.mozilla.org/en-US/firefox/addon/crash-me-now-simple/?src=ss) 4. After the restart - restored the pages 5. Navigate really fast from one tab to the other until there is no spinning sign left in any tab Expected results: Step 5: the content of the pages should load properly. Actual results: Step 5: The content of the pages is white and Nightly becomes unresponsive. Killed Nightly and after the restart, the following crash reports were generated. https://crash-stats.mozilla.com/report/index/42713a00-db97-4a0a-bc7a-54a760170622 https://crash-stats.mozilla.com/report/index/a0b50be6-b631-40b9-b228-e53a30170622 https://crash-stats.mozilla.com/report/index/f7ad4084-ebf1-4850-a227-6bdfb0170622 https://crash-stats.mozilla.com/report/index/72a5ab14-4167-466c-b94b-0770b0170622 https://crash-stats.mozilla.com/report/index/65bf94f5-ea9c-41cc-9ecd-330550170622

Following the steps from the Description, I also got a crash on Firefox 54, that is very similar with the already mentioned signatures: https://crash-stats.mozilla.com/report/index/0ec5bd64-ed2f-4d2b-8e44-ecf370170622
The symptoms and the code involved looks heavily related to bug 1316632: https://bugzilla.mozilla.org/show_bug.cgi?id=1316632#c33 David, could that be the case that the submitted fix didn't cover this scenario?
I can't really tell what is going on in those crash reports. It looks like the IPC channel to the compositor is dead. But if the GPU process isn't enabled (it is disabled on Linux), the compositor bridge should never be shut down without the whole process going down.
