Fresh install of Windows 10, fresh install of Firefox, fresh install of Dropbox.

I was trying to log into Dropbox to authenticate the app, but every time I got to the part where I had to enter my 2fa it would say it was expired. I grew concerned that I was hacked and it was changed, but trying it on my old computer it worked fine.

Then I said fine, I had accidentally paired my Dropbox account with my Google account years ago, so I guess I'll use that. So I logged into Google, and then clicked sign in with my Google account, and I got stuck in a loop where the page was refreshing everything few seconds.

The page would load, it would say "signing you in with your Google account", then it would say at the top in red letters something like "sorry, you haven't signed in recently enough to do that, please log in", and the entire page would refresh and start the loop over, "signing you in with your Google account" etc etc. I left it go through several cycles, it was never gonna work.

It was about then that I guessed that Firefox might be the problem, and it was 🤷‍♂️

The only non standard thing about my config, is that Windows is inside of a VM. That could very well be it too? But edge was also in that same VM, and it worked. I only used edge because I'm trying to keep the VM light, so I didn't install chrome for a one off thing.

I don't know why I got down voted in my earlier comment, I'm not pooping on Firefox. I honestly want it to work, and am still going to use it. But the facts are facts, I literally just ran into this issue yesterday 🤷‍♂️
