Thank you for the review! I do have things to polish up but I am glad to hear it works for you. Also, there is some amount of options, if you head over to the Add-ons Manager (about:addons) and select Twitter Unverified there is a preferences tab. It isn't pretty but it works, just keep in mind you may need to reload the Twitter page for some changes. I will work on documenting this better (and down the road making things look nice).
Again, thank you!
