Are there Firefox extension (or any other browser) that allow to send arbitrary POST data to a webpage?

Question

I want to test the security of a website of mine and I would love to have an application that is able to send POST data, if it's even possible..

Thanks

Answer 1

I think Fiddler will allow this.

Answer 2

Yes, there are two I know of:

• Tamper Data

• Modify Headers

Answer 3

I believe LiveHTTPHeaders can do this (http://livehttpheaders.mozdev.org/).

But you need to first capture an actual GET/POST request, then click "Replay...". There, you can edit your request (including the headers) as you wish.
