All email links have stopped working from both Windows Mail and Thunderbird. It is probably caused by a recent update to Firefox. How can I sort this?

It was OK until a few days ago but now no links work in either Thunderbird or Windows Mail. I have changed nothing so I can only assume that this is another case of an update changing things without my knowledge. Links within web pages still work. Firefox is the default browser and we have been using Windows Mail and Thunderbird (gmail and googlemail) for at least a couple of years on this computer.

Open your firewall program. First check the settings. Make sure that the program is set to tell you if a new program wants access to the web. Then go to the list of programs the firewall has. Make sure that all the programs you want to access the web are set to ALLOW. If it is set to AUTO, the firewall may not allow access.


This problem occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again:

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version)

  • Remove Firefox from your program's list of trusted or recognized programs, then add it back. For detailed instructions, see Configure firewalls so that Firefox can access the Internet.
