Series of posts about broken software. Short stories.

Today, Firefox.

Turns out to be that closing the window of the browser has different behaviour for window x button and Quit in menu.

Click on menu will close the program and bring you all the tabs back with next launch.

But on the other hand, closing the window with x button will wipe all the tabs out, so next time you open window -- that would be brand new. Even if you configured browser to start from place where you've left.

And that is because closing the window is not closing the session.

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