Saving Tabs
Is there a way to save a session or your set of tabs? My "Open previous windows and tabs" is checked on. But occasionally the app will erase the tabs when you've relaunched or quit the app. Such an easy request for Mozilla never to implement into the feature of this web browser.

On Mac closing Firefox can be more complicated because you can close all open windows, but keep Firefox running with the menu bar visible or minimized in the Doc.
Make sure to use "Quit Firefox" with all windows still open, especially if you want to use "Restore Previous Session". Otherwise check "History -> Restore Previous Session" and "History -> Recently Closed Tabs/Windows".
