While surfing, if by chance you close a tab and then realize you want it back but don't remember the URL, there is a unique feature provided to you by Firefox and many other browsers as well. You are provided with an option to reopen the closed tab(s). Here we explain you how.
For instance you have two different sites open in two tabs
1st tab: Dummy Essentials
2nd tab: Yahoo
Now if by chance, you close the second tab
You can reopen the closed tab by doing a right click on Dummy Essentials tab and selecting the option “Undo Close Tab”.
And your closed tab reopens!
Now the question arises, in case you have more than two tabs open and you close all the tabs and only leaving the first tab “Dummy Essentials” open.
Just remember that the last closed tab opens first.
For instance you have three tabs opened now.
1st Tab: Dummy Essentials
2nd Tab: Yahoo
3rd Tab: Google
And you close Google & Yahoo
Now as we mentioned earlier that the last closed tab opens first. So, repeat the same process to open the closed tab.
Once you re-open the Yahoo tab, right click on the Yahoo tab to re-open the Google tab.
And here you are..!! All your closed tabs have reopened.
