Hello there lahteb. We have read your message. We try to help you.

If you receive messages from someone else the hypertext or urls sent to your email inbox don't work?

Or is it that the urls you type to start browsing in your Firefox browser just don't work?

can you be more specific? Did you had an update ,with version 78.8.?

Greetings Firefox volunteer.

Hello there again. Lahteb.

If you try to restart Thunderbird in safe modus see if the error goes away If the links you’ve try to connect to works in safe modus. Then it’s maybe caused by bad add ons in your program. Try search where that bad addon one is located? Some Anti virus program s also block s some time a connection to internet use. Or VPN service.

I have the same problem. (See my earlier request for help here.)

Hello there nkennington. We have read your message we try to help you.

Oke,just a moment. That problem was solved? We had suggested that safe modus would work for you? Also for lahteb was this the suggestion.
