Worthless rubbish that does not work, period. Rated 1 out of 5 stars
I have tried this joke of an Add-on for over a year now and have ever yet to see it correct anything of any kind in my (url) Address bar. The truly comical part is that by disabling it, my natural Firefox browser was better at correcting my address bar mistakes on its own upon tapping the [Enter] button, likely because it actually did something, unlike this pointless extension.
This Add-on only "adds" to the bloat of an already brilliant browser. I DO NOT RECOMMEND THIS ADD-ON.
