Group Tabs

Now tabgroups in Firefox stopped working, and many forms in Firefox stopped working on many sites, there is realy no reason to use Firefox anymore. This extension in awesome. It realy works perfectly. This extension is why Chrome is now my new browser!

The extension moved all tabs into one window on startup. When I opened the browser with a middle-click on the taskbar, the extension lost all tabs except the new tab the middle click created.

This extension actually closes tabs that aren't in the group you are viewing. If you switch to that group, it will load the tabs as if you had just navigated to that page for the first time. The same functionality can be accomplished by organizing your bookmarks into folders, then right-clicking on the folder and clicking "Open all bookmarks".
