Firefox worked fine this morning, up until I allowed the update to 73.0.1. As soon as it restarted, all my tabs crashed. I tried restarting in safemode, with no luck. Tried checking crash reports, and to my surprise, there were none. Not a single crash report in about:crashes, nor in the appdata folder. I tried doing a clean install. No luck. Still crashes, and no reports. Tried reverting to an older version. Still crashes, no reports. Tried the about:config fix with the "browser.tabs.remote.autostart = false / browser.tabs.remote.autostart.2 = false" thing there. Still crashes, still no crash reports.

I have not been able to find any other possible fixes for this, and I can't find any reason for this to keep happening even after clean install.

Microsoft edge and chrome both work perfectly fine. It is only firefox that is having issues.

We have recently seen multiple reports that Bitdefender is causing issues with tab crashes in Firefox 73.

Ahh. Well, for right now, I think I have things figured out. I switched to the 32bit version of 73.0.1, and that seems to have resolved the issue for the moment. But if anything happens, I'll try removing bitdefender.

Thank you for letting me know!

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.
