When I open a new tab I get an error message if I do not have the web address. This is the message I get.

ie general search for stained glass patterns

Error Description: Could not process this "GET" request.

I try to entrer a website www.wizink.pt and the following message appears

400 Bad Request Request Header Or Cookie Too Large

How can Ichange the settings in order to solve this?

I subscribe to my city's newsletter. It gives quick links "click here" to register for a class, "click here" for information about an upcoming parade. I used to be able to click and get it. Now it tells me It can't find the site OR I might be connected but behind a firewall. There are too many options and too many terms, I don't know what to do, I just want to click links from my city newsletter, and get taken to them. Help???

Hmm. We’re having trouble finding that site.

We can’t connect to the server at vu4mbwlab.cc.rs6.net.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Hello, when I browse the internet, randomly the certificates seem to break as I get https certificates for sites that seem to have nothing to do with the sites that i intend to visit. Then errors like the ones in the screenshots appear. Usually reloading the website helps and then the certificate displayed seems to be correct. I did make sure to upgrade to the latest version of FF (136.0) and I did clear all cookies, but it didnt help. I do not really have any idea where to start searching or what might cause this, tia for help. kind regards Thomas

Hi.

Can't access router gateway since last week

Gives error: Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

Gateway is http only, I can access it fine via Edge and Safari iOS

I tried disabling https-only though it used to work fine before with a saved exception.

Made sure Win10 firewall allows Firefox for private/public

Followed the help link and deleted the previous certificate from the certificate manager, but I can't find anything relevant under the servers tab

I'm at a loss. Many thanks in advance.

I am being prevented to access any sites I need just because they require some personal data from me. After the initial Norton (1). The message I receive -

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:8080.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

HOW TO CONNECT

I went to work and when I returned a new router was installed and ever since I get errors on almost all sites I visit. It is the potential security issue, requires secure connection and when I look into the info it says the certificate is being denied because it is self signed. And anytime I go to hit learn more I receive a 400 error and cannot continue. I am also unable to update apps I have on my pc or connect to the internet using anything besides a browser. I get the same kind of error on edge as well as Firefox.

I have already set things up so I am using no proxy and I do not have https only mode enabled.

The only constant is that I can open YouTube and watch videos. I thought this meant it was a dns issue but I have tried several fixes for dns issues and they didn't work.

I would attach photos of the error but Mozilla is also unable to open due to the errors so I'm filling this out on mobile.

My banks account pay bills page will not let me enter. Everything else works as it should. I can get to it on my phone. I use this feature on my desktop this problem comes up.

The error SEC_ERROR_REVOKED_CERTIFICATE means that the website's SSL/TLS certificate has been revoked by the certificate authority (CA). This prevents secure connections because the certificate is no longer trusted.
