Starting Iceweasel

["Ethan Rosenberg, PhD" <erosenberg@hygeiabiomedical.com>]

Dear list -

Thanks for all your help.

Finally, I can start Iceweasel from the command line [sort of]: 
iceweasel -no-remote localhost/choice.php width $1280 height $800

The above works.

But ... in a store.desktop multiple windows are opened.

#!/usr/bin/env xdg-open

[Desktop Entry]
Encoding=UTF-8
Name=Store Program
<snip>
Exec=iceweasel -no-remote localhost/choice.php width $1280 height $800
Terminal=false
X-MultipleArgs=false
Type=Application
Icon=iceweasel
Categories=Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/vnd.mozilla.xul+xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;
StartupWMClass=Firefox-bin
StartupNotify=true

=========
FYI Iceweasel is NOT running when I issue the command or click on the icon.

TIA

Ethan

PS
The suggestions on migrating icedove to Thunderbird look excellent.

I'm reasonably good at three things at one time, but six is a little 
much.  As soon as I can climb out of the hole I am in, I'll do the 
migration and give a detailed answer.
