Firefox doesn't remember window positions for Windows 10 using multiple desktops.
I'm a website developer working on multiple projects at a time. My workflow in Windows 10 is to create a new Desktop and open the windows in 1 of 3 monitors I have for that project in the new desktop. This all works great except when I closed Firefox. When I reopen Firefox all the windows are in the main desktop and on the monitor it was last on. Firefox does not remember which desktop the windows were open on.

I think FF opens the last Open Browser and unless you had chosen the option open closed Browsers it might not remember them. Also I think unless you have expanded Windows open it will open only in the Main Windows. I know I seen it happen on a two monitor setup where any windows screen was on the Main unless you had expanded Windows then it would open possibly on the screen it was on.
They all open on the correct monitor, and all on Desktop 1. I can go to the overview and drag them to the correct desktop, but it's hard to tell on some windows what the content is to know which desktop to drag it to. Plus I have a lot of windows open on each desktop.
