Just cannot use a browser without this. Amazing.

It's a fantastic tool, please improve it! For example loading bookmarks directly in side view or a bar on the left with bookmarks (icons) to open directly in side view.

nice... work by mozilla team...

Je l'utilise avec mes marque-pages =)

It really is very useful! Thank you!

I find the Side View feature very useful - it allows me to keep down on the number of tabs, while allowing multiple window experience that is more streamlined then opening multiple windows. For a single monitor user it's a must-have add-on!
