Preview Tab Contents In Firefox

If you are a Firefox user, which by the way, is the choice browser of computer techs; I encourage you take a look at the Firefox extension called TabScope. If you are not familiar with browser extensions (sometimes called plug-ins or add-ons) then you do not know what you are missing.

A browser extension is a computer program that extends the functionality of a web browser in some way. Depending on the browser, the term may be distinct from similar terms such as plug-in or add-on. [ Wikipedia ]

TabScope is one of those extensions that I have installed to enhance the functionality of my browser session. With TabScope installed you can hover your mouse over a browser tab to get a “real-time” thumbnail preview of what is open behind the tab. The “cool factor” with TabScope is that you can resize the thumbnail size and you can actually interact with the thumbnail.  In other words, when the thumbnail is open it is like having a mini browser window open that you can click on the links/buttons and can navigate back in forth. This is very useful if you are working with and toggling between numerous browser tabs.


I do have to say, when I installed TabScope the thumbnails were a little small for my eyes; therefore, I went into the settings and doubled the size of the thumbnail previews.


If you are person who multi-tasks in their browser, like I do, with numerous tabs open; then, TabScope is a good browser extension to install. You can download and get the TabScope extension [ HERE ]. Again, as a reminder, this is a Firefox browser extension that works with the Firefox browser only.

  1. Very interesting Rick.

    Quite similar to one I have been using for years, and which I couldn’t live without – CoolPreviews.

    These utilities are invaluable for Bloggers who need to test enclosed links in their posts. You don’t need to go to the linked site, the preview lets you know the link is live.

    Thanks for this.



  2. Bill,

    What a great “tip” for using TabScope and CoolPreviews…

    Also, I think I read somewhere that tab previews will be a new feature in a future version of Firefox (3.6); however, it will be interesting to see if the features are as robust as these add-ons…

    Thanks for dropping by…



  3. Excellent resource and tip. Thanks for this one.

    But rather than just leave a penny in the tip jar, I’ll give you one in return – one of the most useful tools I have come across in Firefox is Colorzilla – a right click available color picker for identifying any color within your browser. The benefits should be obvious.

    (disclosure – I have no direct tie to the above, Im just sharing)
