Say I have a window of mostly music that I want to open with shortcut a, and a window of work stuff that I want to open with shortcut b. Is there anything I can do to get firefox shortcuts to remember the windows separately? I don’t want to use chrome or a different browser as the second window, but that would work for specifically what I want to do.
If you mean you want different desktop shortcuts or menu items to use different Firefox profiles, you can pass the profile as part of the command the desktop shortcut or menu item runs: https://support.mozilla.org/bm/questions/1171685
