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.
This doesn’t work with shortcuts (that I’m aware of) but there’s a plugin called “Facebook Container” that sets up virtual browsers within Firefox. Session data, cookies, etc is independant between containers. And it’s not just for Facebook, you can setup as many containers as you like (within reason, best to keep the number low) and when you open a link (right click) you can choose which container to open the link in. It’s good for isolating web sites (e.g. so Facebook can’t see what other websites you’re logged into) but also allows you to log into the same website with multiple accounts. For example a personal GMail account and a Work GMail account. Check it out here: https://addons.mozilla.org/en-GB/firefox/addon/facebook-container/
