Now, A reply from "Paul" said this is a google issue and it is not. I have 3 gmails and I can't open one of my email accounts using Firefox but I can open it through Microsoft Edge. I have emailed Google about this so far I have been ignored so, when I discovered that it would open through Edge and Chrom this told me it's an issue with Firefox not google and the problem started with the last firefox update. So, I already know it's not an issue with google and I have no problem with my other email accounts just the one.
