This crash is in the graphics layer, has nothing to do with accessibility or JAWS. Moving to the relevant component.

(In reply to Marco Zehe (:MarcoZ) from comment #1) > This crash is in the graphics layer, has nothing to do with accessibility or > JAWS. Moving to the relevant component. bunch of crashes like [1] in the bug says it crashes in fsdomnodefirefox.dll, which is JAWS dll. also it says that "Multiprocess Windows 1/1 (Enabled by default)". Afaik e10s Firefox is not yet JAWS-ready, and there is a whole bunch of crashes associated with it. [1] https://crash-stats.mozilla.com/report/index/849fdebb-264b-4583-90c7-045832170306

Marco should this be moved back to our component and treated like bug 1277072? It isn't clear to me if the stacks provided point to more than one bug or not...

I believe these might be related: https://crash-stats.mozilla.com/report/index/3536969b-2a2f-4deb-8d7e-f16632170307 https://crash-stats.mozilla.com/report/index/692600f1-a5ac-4169-8472-63fc62170307 https://crash-stats.mozilla.com/report/index/71a941b4-6298-445b-8088-68c1c2170307 Mind you not all of them crash inside FS dlls

Yes let's move it back.

This is fixed by JAWS, but those fixes have not yet made it to the release channel. They have provided me with test builds.
