Seeing how many of the users report the problem goes away if they let Firefox report as Chrome I personally am rather sure this is intentionally from Googles side:
Yes, I believe there are some real bugs, but I also think Google do take advantage of "useful" bugs to force us over to Chrome.
So I have decided to put my money where my mouth is and since last month I am a nebula subscriber. I am also considering Patreon.
Please consider doing the same, and please do write competition authorities in your country and do ask about when they will look into Googles rampant abuse of market position.
