Problem with Epiphany(Web) Browser in Ubuntu Mate 18.04


When I launch the browser without any other instances running, it runs fine…but if an instance of the browser is already open, opening another instance results in the following :

(1) An extra “Starting …” window/redctangle appears in the taskbar.
(2) At the same time the Mouse pointer changes to busy for like 15 seconds

then everything becomes normal… “starting…” rectangle in the taskbar goes away and the mouse pointer becomes normal…

This also happens with Midori in the exact same way…

Doesn’t happen with Firefox or Chrome
I find it very weird…

Maybe I should edit the .desktop file and change the exec line somehow ?

I appreciate your help
