I just wanted to comment the existing Ticket https://support.mozilla.org/en-US/questions/1291420 Which for any reason has been archived. I have the same problem and it is in the way every day: Quote from the ticket refered: >I use multiple virtual desktops (let's call them A, B, C, and D) on Windows 10, and have a separate Firefox >window running in each. >When I use the browser on, say, desktop D, then switch to desktop A and click a link from another application, >Firefox moves me back to desktop D and opens the link in a tab back there. If I had opened a blank tab in the >browser on desktop A first, the link would have opened in that window. >How can I get Firefox to open links in the browser window that is on the current desktop, instead of in the most >recently used window? Chrome works this way, so I don't think it's a fundamental limit of Windows virtual >desktops.
