Even for a small task like switching a tab we tend to use the mouse. Now, the same action can be performed using the Ctrl key in combination with a number [1, 2, …] (to jump to a particular tab) or the Tab key (to cycle among the open tabs).
Step 1: Open a Firefox tab and enter about:config on its address bar. Hit Enter.
Step 2: You will be shown a warning message. That is nothing to worry about and you can click on I’ll be careful button.
Step 3: Start searching for ctrl. A few preferences will be filtered. Look for the one reading browser.ctrlTab.previews. By default the value against this variable should be false.
Step 4: Double click on the variable to change the value to true. After that you can close the about:config tab.
Now, the thumbnail tab preview for Firefox should be activated. Try it out. But remember the keyboard combination- it is Ctrl + Tab and not Alt + tab.
Note: Ctrl + Tab will show the tabs that are open on the current window. If you have multiple windows open it will not pick tabs from those in the background. I wish it did that as well. 🙂
I am not sure about which version of Firefox came with this feature first. So, if you do not find the preference while searching for it, you should consider upgrading to the latest version.
While Chrome may be growing by leaps and bounds and eating into Internet Explorer’s market share, Firefox – which used to be the darling of everyone before Chrome arrived – hasn’t exactly given up on the fight. With interesting built-in features like the one above which do not require any add-ons, the ex-Firefox user who switched over to Chrome might just find new reasons to come back to his old favorite.
