I've just installed SeaMonkey from Ubuntuzilla on Linux Mint 18.3 MATE,
using the instructions at
<https://sourceforge.net/p/ubuntuzilla/wiki/Main_Page/#installation>.
On starting SeaMonkey, it prompts to "Use SeaMonkey as the default
client for:" with "Browser" and "Email" preselected. I click OK, and it
does appear to be correctly set as the default application - .html
files, http: URLs etc. from other applications open with SeaMonkey.
However, every time I start SeaMonkey it prompts again to set it as the
default client. I /could/ just untick "Always perform this check when
starting SeaMonkey" and I expect it wouldn't prompt again, but I'm
pretty sure this prompt is only supposed to appear if SeaMonkey is not
already the default.
Ubuntuzilla sets up an entry for SeaMonkey in the applications menu
(file at /usr/share/applications/seamonkey-mozilla-build.desktop), but
I'm not sure if there's something else that needs to be configured in
MATE to enable SeaMonkey to detect that it's already set as the default
browser and mail client? Or perhaps this is a problem with SeaMonkey
itself, possibly related to
<https://bugzilla.mozilla.org/show_bug.cgi?id=1036903>?
I did notice that having SeaMonkey set itself as the default client
creates a ~/.local/share/applications/userapp-SeaMonkey-WYLOAZ.desktop
file and adds references to that into ~/.config/mimeapps.list, rather
than referencing the seamonkey-mozilla-build.desktop which defines the
menu item. Editing ~/.config/mimeapps.list to point to
seamonkey-mozilla-build.desktop doesn't make any difference though. I've
also tried using xdg-settings and xdg-mime to configure similar
mappings, and selecting SeaMonkey as the default web browser and mail
reader at Mint's Menu > Preferences > Preferred Applications, but
SeaMonkey still prompts to be set as the default client every time it
starts.
Has anyone got the default client check to work on MATE, or is disabling
"Always perform this check when starting SeaMonkey" the only way of
avoiding the prompt every time? I don't really mind doing that; it would
just be nice to have it work properly if it just needs a bit of
configuration.
Thanks,
Mark.
