Browser agent extensions causing FireFox issues for Gmail accounts. How can this be fixed anyone please...

Client has tried all the different FireFox extensions but nothing works. He gets the Google error about the browser not being secure so isn’t able to login to the account.


Before when it happened it was only when he tried to access the YouTube studio. It works fine when the extension is deactivated but then he’s accessing accounts with the same browser agents all the time which isn’t good.

please check if any addon is installed for proxy/ports.

Yes, there are but those aren’t the problem. The issue is 100% the browser agent extensions he’s already checked that by turning them off one at a time. All work fine besides browser agents.

my assumption is that some tcp/udp port is open

So you think he should try some different proxies extensions and see if that fixes it then?

yes, you may use reputed addons which u can find on github too
firefox doesn't actively monitor addons which is major security issue.

Actually they do if you look many are marked as incomparable with the latest versions due to security issues. The client said he might need to add an older version again. I don’t think using github would help in this case

what i did is just turn off the user agent when singing into the account, then once signed in turn it back on. it didnt create any issues for me

Thanks, I’ll tell him to try that. I think he’s worried that the same browser agents will be used for X accounts and might cause bans
