Rated 4 out of 5 stars
Great addon, I have mostly used it only for the tinyurl feature for several years now.
Given 4 stars because there's no way to disable the annoying 'balloon' notifications after creating a tinyurl, because they cover up the address bar in FF4. Wasn't a problem in previous versions of the addon and Firefox.
*clicks Tiny button* "Tiny URL now ready (Check the location bar)" Thank you, Captain Obvious.
