I've experienced this on two different operating systems. One is Win10, installed along with Adblock Plus, Noscript, and Facebook Container. The other is Catalina, with just Noscript installed alongside. Both hang on startup.

On Win10, but not on Catalina, if I go into safe mode and manually dump the disk cache, the next startup works fine...but the one after crashes. I wonder if this has something to do with the new cache partitioning in Firefox 85?

This looks like it may be a Firefox issue globally. Others are reporting it here: https://bugzilla.mozilla.org/show_bug.cgi?id=1689032, and I just encountered it myself. I can't reproduce it though, at least not yet. I'll try downloading 84, installing RECAP, and upgrading.

Tried all that. Couldn't reproduce. Shoot.

It kicks in consistently for me when I reenable RECAP, even if that's the only extension active. I have no idea why. Zero idea also why it's only affecting two out of now four machines.

(It's worse on Mac, because I can't even get into safe mode.)

On PC, firefox started in safe mode. It would then start again in normal mode if I 1) disabled RECAP via the extensions menu, then restarted, or 2) emptied the disk cache.

On mac, Firefox would only start if I manually removed the RECAP XPI from the relevant extensions folder.

Right? So odd. Before I figured out RECAP might have something to do with it, I assumed that something was off about my cache.

I haven’t experienced this in later versions of Firefox and suspect the FF bug was the cause, however I haven’t spent more effort digging into it to confirm. Since I don’t experience this anymore and haven’t seen other comments I would be fine closing this issue.
