OneTab is an extension for Chrome and Firefox designed for folks like me who typically have dozens (occasionally hundreds) of browser tabs open.
OneTab adds an icon to the browser that, when clicked, converts all of your open tabs into a single page list of links.
The list is interactive so I can quickly remove links/tabs that I’m no longer interested in as well as re-open all or just some of the links. There’s even a way to share the link list so, for example, I can close all the tabs on one PC and then re-open them on another PC.
Just a nice, small extension that does one thing and does it very well.
