Links inside emails won't open
Since today I click on any link inside emails and it won't open on the default browser. I observe that clicking on links is behaving differently. Instead of calling the default browser, Thunderbird is trying to use the http link as a "feed subscription". And I get a message accordingly. See screenshot attached.

Is there any difference when starting Thunderbird in safe mode? https://support.mozilla.org/en-US/kb/safe-mode-thunderbird
It worked later but I dont know why. After changing the setting for Firefox as default browser I think it caused this. Really weird... Then I tried again to change the same option and works.
