Thunderbird itself is using the settings 'network.protocol-handler.app.http(s)' for referencing the to be used browser if one of http protocols is called. The default is set to 'x-www-browser' (see /etc/thunderbird/pref/thunderbird.js) which is linked to another link handled by update-alternates. > $ which x-www-browser > /usr/bin/x-www-browser > $ ls -la /usr/bin/x-www-browser > lrwxrwxrwx 1 root root 31 Jun 19 2017 /usr/bin/x-www-browser -> > /etc/alternatives/x-www-browser > $ ls -la /etc/alternatives/x-www-browser > lrwxrwxrwx 1 root root 16 Mär 30 18:47 /etc/alternatives/x-www-browser -> > /usr/bin/firefox These settings shown above are the default case for a long time, so if Thunderbird tries to open Thunderbird for html links you have some non default settings. The settings for network.protocol-handler.app.http(s) can be modified within your preferences so first have a look into your profile and check if there is something changed. Another possibility to look at is the file $HOME/.thunderbird/[your_profile]/mimeTypes.rdf Here also some different browser can be declared. Look for something like this especially on 'NC:path': > 10 <RDF:Description RDF:about="urn:handler:local:/usr/bin/x-www-browser" > 11 NC:prettyName="iceweasel" > 12 NC:path="/usr/bin/x-www-browser" /> You can safely remove such a entry. -- Regards Carsten Schoenert
