Rated 4 out of 5 stars
I'm a long-time user of this add-on. I, too, recently began having problems with tinyurl add-on translations, they only worked sometimes, even with the latest 2.0 version (I use Firefox 3.0.5). So I chose to use another website to do the conversion as suggested... I chose shrunklink.com, which does seem to work. If I go directly to tinyurl.com to make the translation, it works fine, so the problem is apparently an issue with the tinyurl add-on's interaction with the tinyurl.com website.
