Oh undo function, what would I do without you? 

Well, I would probably be forced to do it again – but that is beside the point.  I love being able to reopen a closed tab or window in Firefox.  It has saved my rear end many times.  This is just one of those Firefox tips you really should memorize.

Tab Restore Shortcuts

If you accidently close a tab, you can bring it back by pressing the following keyboard combination:

Ctrl + Shift + T

The great thing about it, is the newly restored tab keeps all the surfing history too.  You can can keep doing it to, to browse backwards through all the tabs you have closed in your current browsing session.

You can also bring back closed Firefox tabs or windows by clicking on “History” in the menu bar.  At the very bottom, you should see selectable menus for:

• Recently Closed Tabs
• Recently Closed Windows

There you have it.  This tab and window restore tip will help you get out of a pinch more than a few times, so it is a good one to memorize.  This is one of my favorite keyboard shortcuts and Firefox browsing tips, second only to Ctrl + T to open a new Firefox tab.

This extension allows you to undo closed tabs via a toolbar and/or tab bar button or the right-click context menu. Also it comes with a much easier keyboard combination of its own to remember, Ctrl + Shift + Z.   You must add the toolbar button by going to View -> Toolbars -> Customize, then drag and drop the icon where you want it on the toolbar.

Save your lost tabs, and save yourself a lot of wear and tear on your Ctrl and Shift keys while you are at it.  Your keyboard will thank you!
