502958 - Automatically start in Safe Mode when Firefox dies at startup

Status: RESOLVED DUPLICATE of bug 294260

(Toolkit :: Startup and Profile System, enhancement)

Description

[Michael Kohler [:mkohler]]

Firefox should automatically start in Safe Mode after it crashed for x times at startup. This would be useful for all toolkit apps. Specifying until which point it has to go is not that easy, I guess.

(please move this bug to the appropriate component, I've no idea where that should go to - toolkit?)

Fixing bug 347680 will be a big step in this direction.

I suggest to make a meta-bug with this bug.

This should also apply to hangs and DEP deaths, not just crashes.

I don't think so, actually. If we crash at startup, we don't even reach session restore. We usually come into this problem because we're loading incompatible binaries of some sort, potentially from add-ons.
Starting into safe mode will enable us to run automated update and load add-on blocklists in that case, while starting even as far as into displaying the session restore tab already enables all add-ons and therefore will crash in those cases.
We need to hook in very soon in the startup process, in a place before safe mode makes a difference of what we are doing.
