Great tool; may eventually become obsolete as browser debuggers mature, but I still appreciate its clear view of the browser's network behaviour.

Obsolete? Rated 1 out of 5 stars

I found this add-on tremendously useful in early versions of Firefox, but recently I discovered navigating to the browser console (Ctrl+Shft+K for Windows users) and ensuring 'Logs' are enabled under the 'Networking' filter will show the same thing in a sub-window of the current tab; perhaps even more neatly than this add-on can.

Open question: Is this add-on entirely obsolete, or might it still have some use?

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!
