1137269 - [e10s] - all e10s tabs crash [@ mozalloc_abort(char const*) | Abort | NS_DebugBreak | mozilla::ipc::MessageChannel::DebugAbort

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Kamil Jozwiak [:kjozwiak]]

Attachment: testcase.html

Every opened e10s tab will crash instantly when you right click and select "Save Link As..." using the attached testcase.html. When you do this without e10s enabled, you'll receive a "Download Error" prompt message indicating that an "unknown error" has occurred. We should be handling this better rather than crashing all the tabs.

STR:
====

* open fx with e10s enabled and open several tabs (facebook, twitter etc..)
* open the attached testcase.html, right click the link and select "Save Link As.."
* you'll notice that all the opened e10s tabs crash instantly
