Rated 4 out of 5 stars

Very nice. Since I like to browse using the keyboard, this lets me access the tabs I want quickly. A couple of minor issues that I have with the extension is that it clashes with "Highlight all" (alt+a) of the Find Bar. I have to press alt again to deselect the menu bar. The other one is that the Numeric Keyboard Shortcuts only allow you to select tabs 1-10. If you were able to select the full rage of tabs, it would make it quicker to select the tab you want when multiple tabs share the first letter of their title.
