All New Tabs crash, cannot fix by reinstalling (Firefox Dev Edition)

Posted

Cannot browse at all using Firefox Developer Edition.. New Tabs display 'Bad News first: This tab has crashed' Reinstalling does not help, Starting Firefox in Safe mode has also made no difference. Any Ideas what the problem may be?

Does this also happen and does Firefox crash instead if you disable multi-process for tabs?

Yes, Disabling multi-process fixes it... There maybe a problem with multi-process in the latest release, I've been using it a while now without any issues.

Multi-process is still in development and is not enabled by default in releases AFAIK, but only in Nightly builds. So if you enabled it yourself then this is at your own risk.
