This setting is nothing that the packaging is modifying, this is always done within the user context, so your bug report is strictly spoken not a Debian related issue. But this "problem" is a common issue with Thunderbird running on a Linux system. > Not being able to open links by clicking on them but being forced to copy them > over into the browser is a major usability issue. > > I am able to reproduce this bug with a fresh profile. That indicates mostly that it's not a miss configuration of Thunderbird. Setting file type associations on a Linux system works different as it's designed for Windows systems. It's not only done by detecting a file name extension but more relying on detecting the MIME type. So the reason why Thunderbird is trying to open http or https links with the feed-reader is grounded on the association that these links need to get opened with the feed-reader. To solve this you need to find the file were this association is done. Unfortunately there are two places within your $HOME you can add or modify MIME associations. /home/$HOME/.config/mimeapps.list /home/$HOME/.local/share/applications/mimeapps.list And there is one more place were MIME association can be done for Thunderbird. /home/$HOME/.thunderbird/$profile.default/mimeTypes.rdf But this shouldn't be relevant as you say you have the same problem with a new profile. While the transition from Icedove to Thunderbird people have reported similar issues, we added a helper to detect any associations made to icedove. This was only done for the the file mimeTypes.rdf within user profiles. So back to the mimeapps.list files. You should keep an eye an the date of these files, probably the one with the more recent date is the culprit. Make copies of these files before you modify them! Your will find for sure something like this: text/html=foobar Remove any of these lines and restart Thunderbird. There is a lot of information available in the internet about MIME type, their setup and usage. Your problem is based on some non useful made association for html file types. https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types https://support.mozilla.org/en-US/kb/hyperlinks-in-messages-not-working -- Regards Carsten Schoenert
