Firefox crashes and can't use the existing profile when relaunching

Over the past week I've had this error popup a few times when Firefox is launched:

"You've launched an older version of Firefox. Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox."

I haven't yet spotted a pattern, but the most recent time it happened, I had the browser already open and either opened a new window or clicked Firefox in my start menu. The new window showed my homepage (blank tab) but was unresponsive: I couldn't type into the address bar, click a bookmark, or even close the window. The existing window was fine, so I closed that but had to kill Firefox in Task Manager.

When I relaunched Firefox, I got the above error message. Luckily I use Sync, so my many bookmarks are backed up. But of course all cookies have been deleted, so I have to login to websites again.

Firefox is up-to-date (84.0.1, 64-bit) and running on Windows 10 Enterprise. I even uninstalled, cleared out the data in AppData\Roaming\Mozilla (plus Local and LocalLow), and reinstalled.

As I said, this has happened a few times over the last week (3 or 4?) and is starting to get annoying now!

Any ideas? Thanks!

Been having this issue for the last few weeks where Firefox just won't load YouTube properly. In particular, livestreams won't play, chat always show as "disconnected from chat" and I can't even access the profile menu (clicking on my profile pic on the top left just shows a loading icon forever).

Tried the following without any luck: 1. Safemode 2. Clearing all cache 3. Refresh firefox (When I first did a refresh, it started working again, then I went to sleep and the next morning the same problem is back again)

Any help would be much appreciated.
