The easiest thing to do is to make a profile folder (not the same as a Firefox Account) for each person. The profile folder is where your user information (bookmarks, passwords, etc) are stored. See Profile Manager - Create, remove or switch Firefox profiles.

If you want to use the Firefox Sync feature, each person would need to have a Firefox Account under their own email address that they can use.

Hope this helps.

Perfect! Thank you!

The profiles solution sounds like it would help me, too. Once multiple profiles are set up, is it possible to have two Firefox windows open simultaneously that are tied to different profiles?

Since doing the work-from-home thing, my personal matters (email, banking, shopping, etc.) are getting more and more mixed with work related matters (diff email account, shared web drive, contact lists, etc.) I'm looking for a way to keep them separated, while being able to easily switch from one to the other.

Hi sefridie! Yes, what you've described is totally possible and there are a couple of ways to go about setting this up.

The way I usually recommend is to make two separate Firefox shortcuts on your desktop. Then, you would need to add the appropriate Command Line Options to the shortcut target.

On Windows, that's done by right-clicking on the shortcut and selecting Properties. If you click the Shortcut tab of the window that appears, you will see the Target text box that points to Firefox. You would just need to add -new-instance -P "PROFILE_NAME" to the end of the target outside of the quotation marks.

The -new-instance allows you to run more than one Firefox profile simultaneously. The -P tells Firefox what profile you want to use. Obviously, you would need to replace the PROFILE_NAME with your profile name (keep the quotations). That can be found on the about:profiles page in Firefox.

If you set each shortcut to open a different profile, it should work the way that you are hoping for.

Hope this helps.
