Snaporama is an experimental Firefox add-on, which is quite handy for the users looking for a way to save multiple tabs for future reference. Using Snaporama, you quickly "snapshot" groups of tabs into a bookmarks folder and open these snapshots into new Panorama groups. Hence, you can organize your tabs groups efficiently.
How to use Snaporama
Snaporama is an experimental and restartless Firefox add-on, and can be installed from here. Once you have installed it, you can notice its ‘camera’ icon on the add-on bar of the Firefox. Click on this icon, and select the option "Create new snapshot". You can assign a name to this tabs group. Later, you can click on the snapshot gallery icon (the icon next to the ‘camera’ icon), and open a snapshot into a new Panorama group.
The Snaporama uses Firefox’s bookmarks folder feature to save tabs groups. It simply saves tabs groups as bookmarks folders – and open with a new Panorama group. Hence, it complements the Panorama feature. Excellent!
