Appears since Firefox update 153.0(20260715202819) installed July 2 2,2026@4:39:31had many issues with my email app. I have a ticket #447010. I cannot access my email on opt online.net with out errors. Mozilla support sent a response which I can’t
I am unable to access email or sign in to optonlinei.net. I opened a ticket with Mozilla support #447010, they responded and I can open the email. A couple of error messages; 431 request header field too large, the application is having trouble connecting to the server..The layout has changed since this update, bookmarks have move some where, start up has changed, clicking Firefox no longer brings up email sign info. Something has really messed something up that once was so nice and convenient. May someone can help or correct. I am running windows 11 on a hp desk top and have run Firefox four years.
