Firefox is not letting me access Xero.com which is my primary use of working with clients.

The message I get is

Access Denied You don't have permission to access "http://go.xero.com/app/!hQMY2/dashboard" on this server.

Is there anything I need to do to allow go.xero.com be used.

Mozilla is giving a security warning when I am attempting to download and view messages known to be valid and safe but are caught by a 3rd party spam program and placed in quarantine status.

Secure connection failed and Firefox did not connect message. Why? Received when trying to sign on to sbcglobal but that has changed. Rude sbc agents said it was a Firefox problem. I am trying to save 25 years of family research.

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)

Two days in a row I have not been able to get into my e-mail due to an error relating to the sign in to Bell services : webmail.bell.net. PR_CONNECT_RESET_ERROR comes up every time. A Bell employee managed to get it sorted briefly yesterday by resetting my password for this Bell service, but despite having embedded that new password into the incantation to get into the site supposedly, the error is happening again today! They cannot get back to me in less than 24 hours (and it may be 48) so my tax returns are definitely going to be late this year..... added to the usual problems of staff unable to speak comprehensible English, frustration is making me feel quite ill. Browser is Firefox and operating system Windows 11

error message:

Firefox Can’t Open This Page

To protect your security, vimeo.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Report errors like this to help Mozilla identify and block malicious sites

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

I keep getting 'Bad Request
