Consider creating sets of bookmarks as a quick way to get your favorite pages open all at once.

Here's what I mean: You may have noticed that you can create folders in your bookmarks. (See: Use bookmark folders to organize your bookmarks) Each folder has a line at the bottom saying "Open All in Tabs" which will open all the bookmarks in that set immediately.

There is an extra step compared with using the home page setting, but on the other hand, you don't have to open all those pages every time you want to open a new window.

If you have a bunch of tabs open in the current window that you want to save as a set, you can right-click any tab and choose Bookmark All Tabs. This will prompt you for a folder name and add it to the Bookmarks Menu. Of course, you can always move bookmarks in and out of that and other folders as needed.

For a more personalized (less shared) experience, Firefox lets you create separate profiles, each with its own settings, including separate home pages, bookmarks, and add-ons. (See: Profiles - Where Firefox stores your bookmarks, passwords and other user data) This may be a little involved to set up the first time, but over time it probably will help keep the peace.

Switching profiles requires shutting down Firefox, so if you need to leave work open in one Firefox window while your spouse works in a different window, this might not be the right approach for you.

You can add -no-remote to the command line to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously.
