Firefox 2.0 and undo closed tabs
If you want to undo an accidental tab closing, you have many ways to do:
- right click on the tab bar, select “Undo close tab” and repeat it as many time needed.
- open “History” menu then “Recently closed tabs” then the tab you want to reopen.
I've accidentally found a third way: it's the keyboard shortcut <cmd>+<shift>+<T> on Apple computers and <ctrl>+<shift>+<T> on other systems.
