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.

There is a site I visit regularly that will not connect. I get an error 429 code. This doesn't happen with any other site I've used recently, and I can access the site with my iPad. I've tried clearing cookies and restarting the computer, but still can't get to this site. Any ideas?

Getting around 20ms for DNS lookups so thats not the issue. Why do I see Error Code: NS_ERROR_OFFLINE maybe once every several days when this Firefox has never been in offline mode and never will be? Env is MacOS 26.5.2 with current Firefox installed.

Have cleared browser cashe and rebooted, all to no effect,so how can I complete an upload of requested information if I can't get through and keep getting the 403 error message?

I posted a question to the community forum and received a reply from JBR. When I try to respond to the reply, I get this error message

Looks like there’s a problem with this site

The server at support.mozilla.org sent back an error: 406 Not Acceptable What can you do about it?

   Check to make sure you’ve typed the website address correctly.
   The site could be temporarily unavailable or too busy. Try again in a few moments.

I have tried to respond multiple times over the past 24 hours to reply using this URL that appears when I click on the view and reply link in the email.

How can I get support and communicate with forum members trying to help me since this link does not work?

Thanks.

Halfway through today I'm unableto access three sites which I use regularly.using a VPN: 1337X.TO EZTVX.TO THEPIRATEBAY.ORG

Getting the error message:

An error occurred during a connection to thepiratebay.org. PR_END_OF_FILE_ERROR Error code: PR_END_OF_FILE_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem.

I am able to access THEPIRATEBAY.ORG with Opera <ptooh> so the site itself obviously doesn't have a problem.

I've tried changng my VPN location from the UK to Amsterdam, NL and to Washington, USA but none of those locations have helped.

My wife needsher daily fix of American soaps and Police dramas which never get to us here in the UK

How can I get around this, I really don't want to go down the TOR route unless I absolutely have to.
