Welcome into Linux, where such a simple thing to think about is a pain in the neck for years…
I can not drag and drop that link into icon tasks list in the panel, UBudgie 19.10 here too ( which sounds normal to me since it’s not a
.desktop file )You may modify the
Icon= later but it seems to only accept path to local resource.
Ideally this link « mechanism » should automatically grab the favicon ( if any ).
I don’t know if it’s browser or system specific though.
Now if using Firefox why not rearranging this page :
or bookmarks ?
There is also a nice utility coming from peppermintOS called ICE, it aims to create webapp ( which is different from links/shortcuts/bookmarks ) for any website using almost any browser - needs some tricks with chromium-as-a-snap but it works - I use ICE ( .deb here, v6.0.6 ) for sites like google-drive/maps, deezer, fip-radio ( as you may see on my screenshots ). Now each of these websites have their own .desktop file, appear in app’menu and are displayed in « naked » web-browser window.
Note that this feature will soon be enabled natively in Firefox - where it’s called SSB, Single Site Browser.
