URL Fixer – The Typo Killer for Firefox
We all hate typos, but we still commit them unknowingly. Things get even worse when you hit the return key in Firefox address bar and then realize that you committed a typo. URL Fixer is a super handy Firefox extension which does the dirty job of fixing these typos for you. It can fix most common typos in both prefix (http:, https:) and suffix part (com, org, net, info.. etc) of a domain name.
These fixes are instantaneous (if you haven’t selected confirmation by right clicking the address bar), it won’t let you realize that you have committed a typo at all. Best of all, it works for country specific domain names such as co.xx, .xx, org.xx etc
If you ever count the number of typos you make on an average day, you’ll get a rough idea of time eaten by these typos. URL Fixer works efficiently and is a real timer saver.
Side note: The functionalities of URL Fixer have been nominated to be implemented in the upcoming Firefox 3.
