I've been looking for an add-on exactly like this for ages. I don't review many things, but after using OneTab for a while I just had to. As a programmer and gamer OneTab allows me to easily manage my browser information while using virtually no resources.

My only complaint comes from the user interface. It's a bit annoying if I want to store a few tabs as I have to navigate through some drop-down menus. I also use the left click option much less than I use the other options. If there was some kind of setting to replace the left click option with the drop-down menu I would love it.

Amazing add-on though.
