Unwanted redirects Rated 4 out of 5 stars
Overall, this add-on is a time-saver, and I've used it for quite a while. However, there are some weird redirects that shouldn't happen with legit urls.
One example I can think of off the top of my head is Overstock.com's url "o.co" This is a perfectly valid url. However, URL Fixer will automatically redirect you to Twitter's service "t.co", which is not helpful and actually wastes time. This can be worked around by always having the prompt appear when you type in a url URL Fixer thinks is wrong, but this mitigates the time-saving factor that is the key to this add-on. Please look into this, dev(s)!
