When I start my Mac, I'd like two Firefox windows to open with two different sets of startup tabs. Is this possible?

I don't use a home page but I want the same windows and tabs when I restart the browser. I leave the windows and tabs open when I exit the browser and have the setting "Open Previous Windows and Tabs". That is the first setting, at the top of the General page in Settings.

Yes. Set the home page so both links are entered with a | is between the links. Example: Google.com|Yahoo.com

Using the pipe (|) symbol only works for tabs in the same window. For multiple windows you likely need to use a script file to be able to specify startup parameters with -new-tab and -new-window switched and URLs between them.

On Linux this would be this code and I assume that on Mac this will work as well. Make sure to set the executable flag on the file. You can find the Firefox installation path on the "Help -> More Troubleshooting Information" (about:support) page.

#!/bin/sh

cd <path to firefox>
./firefox --new-tab URL1 URL2 --new-window URL3 URL4
