Did you stick the user.js in your .thunderbird/profilename dir?
This piece of code:
is supposed to prevent it from asking for a profile in firefox and start in a new tab. In particular the -a firefox part.Code:if $MOZILLA_FIVE_HOME/mozilla-xremote-client -a firefox openURL\("$url, new-tab"\);
Also you might need to recopy the code for openlink.sh because it copied over wrong during orignial post, and that could also be why it's not working right, because of a newline character.
