its perfect

works for me, great stuff, thanks! (why did mozilla make tab switching so useless)

Does what it says on the tin! I really don't see why Mozilla hasn't implemented this! You are a good man for simplyfying certainly many an ADHD tab collectors' search binge and I appreciate it. Simple and effective.

Works fine. Thanks!

It would be nice that these shorcut to be default on FF

Najlepsza!

This is the greatest Add-On. It should be called "MasterTabs." It truly is a *master* at the simplest thing it does - switching tabs with one hand! It's the ONLY tab switcher with that in mind. If you're always working it going up-and-down and up-and-down your long, long list of Tabs, this is it! One handed HEAVEN! :-p
