Any tip you read about shortcuts for Mozilla Firefox is sure to mention that you can easily switch between open tabs by pressing Ctrl+Tab on your keyboard. The resulting action is just a quick flip from tab to tab, which can be quite useful.
Today, however, I’m going to teach you how to spice it up a bit.
Open Mozilla Firefox, and in the address bar type about:config. I know, we’ve been here before, so you should know that you can just skip through the warning that comes up.
Once on the Firefox config page, scroll down until you see the entry: browser.ctrlTab.previews
It’ll look like this:
Change the value to “True”, and restart Firefox.
Now when you have multiple tabs open and you use the Ctrl+Tab shortcut, you’ll see little windows with a preview of the tab!
