Drag the link below to your links bar…

TweakIT

Now edit the bookmark and replace the url with the following:

javascript:void(location.href=’http://api.dot.tk/tweak/shorten?long=’+encodeURIComponent(location.href))

Below is the explanation of the response from tweak.tk

the responses body will contain two lines:

http://bcdef.tk

http://tk./bcdef

The first line will return the created domain name. The second line will display the shortened URL. They both work instantly. The next line is indicated with a carriage return. The domain name is immediately available to use everywhere in the world. Please note that the shortened URL sometimes is not correctly interpreted as an hyperlink in some applications. However, the shortened URL is a real working URL and works in all browsers.
When an error occurred, the HTTP response code will be set to one of the following:
400: Long URL not submitted
401: Long URL is invalid
402: Quota reached
403: Shortname already taken
409: An other error happened
