One thing I like about Opera browser is its ability to show tab previews without actually switching to those tabs. All you have to do is hover your mouse cursor over those tabs and a small thumbnail preview would popup. This helps you to see the contents of a tab without bothering to switch to them one by one. This same functionality can be added to Mozilla Firefox too using the Tab Scope extension. It does not require you to have Windows 7.
Tab Scope is a Firefox extension which enables you to preview and navigate tab contents through a popup. Here are some of its major features :
- Real-time preview of tab contents
- Navigate (Back/Forward/Reload/Stop) through popup
- Scroll pages in preview with scrolling mouse wheel
- Click links or buttons directly in preview
- Automatically show preview for tabs opened in background
You can download and install the Tab Scope add-on from the Mozilla extensions website. After the installation you can hover your cursor over any open tab and a popup thumbnail preview would open up. If you keep your mouse cursor near the top edge of the thumbnail preview, you can see various options like going back and forward, refreshing the webpage, pinning the webpage to Firefox, zooming the thumbanil preview and opening the gallery view.
In the Tab Scope options, you can choose the tab preview window size, the zoom multiplier ratio and animations etc. You can also choose the clicking events like what happens when you right-click over the tab preview window (by default, right-clicking zooms in or zooms out of the preview).
So if you use Firefox and open many tabs in a single Firefox window, then you are going to find the Tab Scope add-on very useful. You can download and install this add-on from https://addons.mozilla.org/…/tab-scope/.
