Firefox keyboard shortcut to retrieve closed tabs
I can’t count the number of times I have been closing windows or tabs and have accidentally a tab that I wanted kept open. In the past, it has been annoying at best and disastrous at worst, but now I no longer have any issues… why you may ask? Because I know a keyboard shortcut that is perhaps amongst the most useful in Firefox… Command-Shift-T . Yes that’s all you need, the next time you accidentally close a tab and you want it back, simply hit Command-Shift-T and the tab will magically reappear again! Now that you know it, try to live without it.
