Post a Get
I've created a PHP script called Post a Get which can be copied to any PHP capable server and used to created a POST request using GET syntax.
Let's say you use GoDaddy as your domain registrar and you would like to see if a domain is available using Firefox keywords, but they don't offer a GET search.
For a traditional keyword, you could construct a GET request like:
https://www.godaddy.com/gdshop/registrar/search.asp&checkAvail=1&fblur=1&tld=.com&domainToCheck=%s
But as of right now Firefox doesn't offer a way to create POST keywords. What Post a Fix does is allow you to construct a POST request using GET syntax and pass it to the Post a Get code.
So if you wanted to submit the above GET as a POST, you would construct the URL and append the special __action parameter with target URL. So the final URL would look something like:
