Unable to connect

Firefox can't establish a connection to the server at www.anz.com. 

   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.

I can connect to other sites but not to many sites that I've always connected to. It is very frustrating. The above message appears which is not even applicable. I have other pages open so there is nothing wrong with 1 or 2. Firefox is permitted to access the web as it already has access. I don't get it!

There is security software like Avast and Kaspersky and BitDefender and ESET that intercept secure connections and send their own certificate.

This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.

Try to disable IPv6 (check for other possible causes as well).

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History").

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks and history and cookies and passwords and cache and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

Can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

Clear the cache and remove the cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Clear the cache":

  • Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now"

"Remove the cookies" from websites that cause problems.

  • Firefox > Preferences > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"
