"Accounts and Sync" isn't the correct component, so resetting in the hope it gets re-triaged.

Can you also check if the video I have uploaded is viewable? Cause it says "Not supported" and you'd have to download it to watch it.

This works fine for me. Do you have any extensions installed? If so, can you disable all of them and test again?

Hi,

So I may more info on this: this bug happens sometimes whenever I reinstall Firefox. You have to clear cookies and site data for Google.com.

I tried clearing all app data a bunch of times and couldn't reproduce this. Let's triage this as affecting a few users for now.

Just to clarify when this problem occurs you then have to clear site data to successfully sign in to Google👍

Ilias, do you have reliable steps to reproduce after a reinstall or does it just start happening after a while?

Hello and excuse me for the late reply,

I don't think there are any specific steps but when I reinstall Firefox it's weird cause I hit "Sign In" and it just refreshes. It will work later on but this happens with or without extensions on. Maybe the extensions are setting something up behind the scenes either way and this occurs before I disable them> Something like that.

I have uBlock Origin and Consent O matic. For example maybe the latter is handling the cookie windows and refreshes the page?

I am unsure if this is the same bug or a different one, but I was recently able to resolve issues with logging in to my google account by disabling max protection for DoH (with a custom nextdns link as an entry).

After I switched it back to default I was able to login to my google accounts again.

It seems to be unrelated to any nextdns blocklists, as I have it also running on the OS level, and observed no issues logging in once I switched out of max protection for DoH.
