[horde] Bookmark feature

[Martin S]

In the bookmark feature it says

"To be able to quickly add bookmarks from your web browser:
Firefox/Mozilla

Drag the "Add to Bookmarks" link below onto your "Personal Toolbar"."

How the ... do you do this in Firefox 38.x+ ? It *seems* that you need to go 
into maintenance mode to add stuff to the personal toolbar and by doing this 
Firefox opens a whole new tab to add stuff from. Draging the icon onto the 
toolbar from that tab or onto the "tool canvas" (or whatever it's called in 
Firefoxian) fails.

Anyone able to enlighten me on this?
(Coming out of testing mode shortly on this server)
