I am trying to log onto the Terminix website but I keep getting an HTTP 400 error on regular tabs. I can get to the website using private tabs. The error says "Headers or Cookies are too big." How do I get past this error?

I have cleared data and cache and the time is correct but I get, Error Code: PR_CONNECT_RESET_ERROR, and will not log in. I have also done a cold, and hot restarts.

when loading up Google search or try to login to Youtube I get this message Secure Connection Failed

Error Code: PR_CONNECT_RESET_ERROR

After updating Firefox to version 153, my Firefox browser has encountered problems with all subsets of the Google site and gives the following error: Error Code: SSL_ERROR_RX_RECORD_TOO_LONG Can anyone help me solve my problem?

Racenet is a formguide put out by News Corp and subsribed to by mug punters like me but i am unable to download it with the message 403 ERROR the request could not be satisfiedbold text

I had opened a support ticket #447010 with Mozella support and they told me that they can not help me, and sent me here. I am "dead in the water" so to speak. It appears that since Firefox downloaded update 153.0(20260715202819) I have had many issues that appear to be getting worse by the day, and now I cannot open or run my email app. I have not wrote down all the errors (sorry) but here are a couple: 431 Request Header Fields too large, the application is having trouble connecting to the server, unable to load the email from Mozella support. After the update (153.0) my bookmarks have moved to somewhere, the sign on for my email app has changed ( use to click on the firefox icon on the bottom tool bar and the sign in box for optonline.net would be there. I understand that sometimes updates (new and improved) make changes to what users have use to for years. Now is have a browser that is not functional and needs to be corrected, I trust you can help and get this sysem usable again, because right now it is not usable. I presume if and when you respond to me issues it will be at this location and not an email. Please help. Thank you

I must find a way to disallow this undesirable and very annoying feature. It is always there even after removing all the protection I could. Please help

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
