How to add thumbnail previews for tabs to Firefox [Guide]

Windows thumbnail previews show what’s open within each of your software windows. As of yet thumbnail tab previews have not been incorporated into browser software. However, Firefox does have an add-on with which you can add thumbnail tab previews to the browser.

That add-on is Tab Preview which displays thumbnails of background tabs much the same as the Windows Vista/7 thumbnail previews. Click on the + Add to Firefox option on this page to add it to your browser. Then restart the Firefox browser.

Once you have restarted Firefox, open a few Web page tabs. Then move your cursor over one of the background tabs. That should display a thumbnail preview of the background tab as in the shot below.

To customize the thumbnail previews, click the Firefox app button at the top left of the browser and select Add-ons. Select Tab Preview from your list of add-ons and click on Options. That should open the Tab Preview window in the shot below.

There you can adjust the thumbnail size by selecting the Size preview width option, and then entering a higher or lower value. Alternatively, you could select the Size preview width to exactly option to enter a pixel value. Below those options you can also choose how the thumbnails display by selecting either the Have preview display the scrolled position and Have preview display from the top left of the page options.

So now you can replicate Windows Vista/7 thumbnail previews in the Firefox browser! They’re a great addition to Firefox which Mozilla should have already incorporated into the browser.

    Opera 12.xx (Presto based) has had that ability natively, even on XP, for aeons. Have no idea about their Webkit based browser.
    Not meaning to be ungrateful at all, but for me, the purpose of a guide should be to instruct on how to hack/tweak/exploit the native abilities of any software. That doesn’t mean I don’t appreciate being informed of potentially useful third-party add-ons (hell, this is one of the main reasons I love Firefox to death!), but that I would much rather if yourself or anyone else, for that matter, could put together or point me towards a set of instructions aimed at tailoring this awesome browser better to my needs and liking, only through changes under the hood, i.e., via about:config. As a start, how do I get rid of that ridiculously Chromey Australis theme without missing out on the secutity fixes and installing a plethora of add-ons? Many thanks in advance for any help and appreciate your hard-work MatthewA.
