Great Add-on - Fix for the new FF versions Rated 5 out of 5 stars

Great Add-on, I'm using it since a couple years now and it's really useful to replay/change HTTP header requests. Since the replay button stopped working with the new Firefox versions I decided to have a look at it and found a temporary fix. If you add in the header this field it should work: If-Modified-Since: *

I made a quick 'how to' in order to patch the add-on yourself and add the field automatically while some update (hopefully) will be released: http://www.mrt-prodz.com/blog/view/2014/09/fixing-live-http-headers-017-add-on

Permet de restaurer un texte précédemment rentré dans un champ d'une page web. Très pratique quand le remplissage d'un formulaire a mystérieusement échoué.

To use with new firefox 29 interface (as a non modal dialog): open the new firefox menu, click customize and drag the live http headers button into the new menu.

Seems broken with Firefox 29 and its new [*cough*/*splutter*] UI. Can only get to the options page with is a modal dialog. Frustrating as amongst a wealth of developer tools built in to Firefox, simply being able to view the HTTP headers ought to be a given, and all searching leads here, to a [*expletive*] dead end.

[Review is based on Mozilla failing to maintain compatibility, such that an apparently invaluable add-on no logner works, though also a reflection that it has not apparently been maintained for several years, and the help link is broken.]

Super! Rated 5 out of 5 stars

Thank you so much for making this! Its has saved me tons of time and is a go-to debugging tool.

Expanded filter options would be great - but whatever - its already great.

Brutal add-on!

Copy options Rated 5 out of 5 stars

There should be an option to "Copy All". Right now, we need to "Select All", then "Copy".

One of the most useful essentials!

This addon is just great!! I found only one small problem, in most cases it does show the 301 and 302 redirects, but when a site redirects the same URL from HTTP to HTTPS it does not. I don't see the 301 or 302 headers, I only see a 200 OK response.

Un très bon module que nous utilisons tous les jours dans notre activité e-commerce. Idéal pour débugguer si vous faites du tracking Google Analytics.

Le plus : vous pouvez éditer et renvoyer une requête.
Le moins : vous ne pouvez pas intercepter une requête à la différence de Tamper Data.

Five stars for this awesomeness.

I tried a similar extension for Google Chrome, but only found something incredibly unstable with bad handling on top of it. Only Opera included a HTTP header sniffer in its Dragonfly developer utility, but since that version of the browser won't receive any updates anymore, Live HTTP headers looks to be the only solution that works conveniently from within a browser.

Great stuff, I'll start using it more and more in the future as I phase the old Opera out.
