Broken Software

Firefox

Turns out that closing the browser window has different behavior depending on whether you use the X button or the Quit option in the menu.

• Clicking Quit in the menu closes the program and restores all tabs on the next launch.
• Closing the window with the X button wipes all tabs, so the next time you open the window it starts fresh, even if you have configured the browser to resume where you left off.

This discrepancy occurs because closing the window with the X does not end the session.

That’s the short story of how I lost ~3 k tabs.
