It is possible this option can be done using Firefox options, but ...
F96CE_XFCE_FUSILLI has got 4 different desktops by default.
A.- Imagine that I'm at destop number 1, with Firefox open at page https/www.google.com.
B.- At desktop number 2, I'm using claws mail, checking my e'mails.
C.- One of my mails, have got a link to puppy forum, so when I click on it, is going to open this page using the default browser (FireFox)
D.- But... when I click nothing happen at destop 2, Firefox doesn't start and I click and click one and another time on mi mail link.
D.- When I think that nothing works and I go to desktop 1 , I feel surprised when I see Firefox with dozens of tabs with the link I clicked on at destop 2.
So...How can I make Firefox open a new sesión browser at each tab??
