What Mozilla product are you having problems with? Or is it all of them?

If you have a problem when trying to update any program, the best way to get around any issues is to download the current full installer.

Firefox browser 92.0 64 bit and Thunderbird 91.1.1 64 bit cannot update

If you have a problem when trying to update any program, the best way to get around any issues is to download the current full installer.

Cannot download anything from Mozilla site. That includes software and updates. I get the following error (attached). Any ideas... Thanks

Delete browsing, search and download history on Firefox {web link}

Remove a single website from your history {web link}

Open the History Manager <Control> (Mac=<Command>) <Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any site settings And Passwords.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
