1. The arrogance of Thunderbird in making it virtually impossible to
force links to open in Chrome instead of FF. I have no idea why they do
this (except of course FF is "their" browser). Their config option
simply does not work (gets ignored).
2. The equal stupidity of Chrome in refusing to open mailto: links by
passing them to Thunderbird or your nominated mailer: instead it takes
no action, and if you try to open a mailto: link in a new window, it
opens a new Chrome window on the same page and does nothing. This is
because it uses a deeply unwise little utility called xdg-open, which is
 is easily fixed by uninstalling Firefox and never using it again.
 has no solution AFAIK. Three years after highlighting this, it has
not been fixed, and you still cannot click on a mailto: link and get a
Thunderbird (or indeed any) composer window, because it's impossible to
reconfigure xdg-open to call the right application.
Yes Dan, "it's hard for a programmer to know how to look up the user's
favorite browser", but only because no-one is prepared to take the first
step and enforce global definition of $BROWSER, $MAILER, $EDITOR,
$TERMINAL, $FILEMANAGER, and maybe a few others.
I have no problem in devs using a more complex system to do this if they
wish, like exo-open, but it need to be configured to work all the time,
on all of the URL methods, and if it is intended to replace xdg-open,
then it should do so and xdg-open should be wiped from the distros.
Maybe one day someone will clean up this mess...it's unnecessary, and
very embarrassing when you try to explain to new users how wonderful
Linux is, and especially [X]Ubuntu, and then have it fall flat on its
face when they click on a link.
