Pages start loading but then always crash and state "Gah. Your tab just crashed." Tried safe mode, tried uninstalling FF completely and reinstalling, restarted computer; same thing. What else to check or do?!

We have recently seen multiple reports that Bitdefender is causing issues with tab crashes in Firefox 73. If you use Bitdefender and suffer from this issue then try to uninstall this software (you may also have to uninstall Bitdefender Agent).

You can possibly contact Bitdefender for support.

It looks that Bitdefender has pushed an update to address this issue. See comment 2.

Issue was apparently on us and was affecting users of Bitdefender AV free. We pushed an update about 2 hours ago with the fix. You should see a drop in crashes as update propagates across market.
