Starting with FF 3.0.6 it no more works to resend a post-header with LiveHTTPheaders 0.14... Not relevant which site or settings, one always gets error:

Request Entity Too Large
The requested resource
xyz
does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit.

I hope the extension will be updated soon!

Excellent add-on that is not quite 100% accurate compared to a tool like wireshark, but very very nice.

Quite useful Rated 3 out of 5 stars

It's essential that there be a way of viewing headers with firefox, and this accomplishes that task. But, it could use some improvements. It would be useful to be able to only view headers for transactions for a specific tab. The improvements mentioned above of allowing copying to the clipboard and saving settings would also be useful.

Debugging cookies and http information is easy with this Rated 5 out of 5 stars

Live http headers is a must for debugging cookie, server and http transaction information. I've told at least a hundred people they must download this extension if they are involved with web development.

Indispensible for SEO Rated 5 out of 5 stars

A "must-have" for search engine optimization, especially for verifying 301 and 302 redirects. Now one of the first add-ons I install when I put Firefox on a new machine.

Super tool! I use it for tracking and analyzing js-requests and it works :-).
It would be cool, if the tool would remember the last settings, so you don't have to reset everytime you open Live HTTP headers.

A suggestion Rated 5 out of 5 stars

It's pretty good to see the http headers. If an options to show all http data, such as headers, contents will be much, much better. For some cases, the Http data is also very important. One of the cases is Flex, with Flex HttpService you can see use LiveHttp Headers to monitor the http traffic , but no contents can be shown, this is not like html, you can view the source.

Thanks for the great tool!

Perfect for my needs Rated 5 out of 5 stars

Perfect for my needs. Due to my studies and job, from time to time I need to get the headers returned by the servers or even the headers sent by my browser. This add-on does this perfectly.

It is also useful for nerds that simply WANT TO KNOW.

Fantastic Rated 5 out of 5 stars

This is useful in so many ways -- whether it's making sure my php scripts work properly, to ripping music off websites which load music asynchronously, or developing software that automatically visits website. In all cases, this is invaluable
