Great replacement for Live HTTP Headers! I didn't expect to find one.
And very active developer.
Thank you for this extension!

Thank you!

Nice

Nice resurrection of live HTTP Headers ! The actual HTTP error codes (200, 404 etc) are missing though and I wish it could also display sent headers, and not only received headers.

Am liebsten würde ich 10 Sterne geben, das Addon ist mit Abstand das Beste um die Live Headers auszulesen.
Weiterhin gibt es auch sinnvolle Optionen welche die Arbeit weiter erleichtern.

Der technische Support ist auch ausgezeichnet - Ein MUST HAVE!!!

Fantastic! Especially the filtering capabilities. Thank you so much!

Replacement for Live HTTP Headers is HERE! Thank you for developing this!

A nice-to-have feature: Being able to choose from a few different themes for the output (vs. the stock black and white).

Thanks! A great addon finally! Nice visual, simple and do what promise..
I'm looking for it after the addon Live Http Headers shut down...

One more tip:
- in search window and replay window, it shows long text lines, so I need to scroll to the side... Can you put a option to put all text aligned? Thanks.
- when I replay a information, the page opens in the same origin tab... There is a possibility to open the replay in the active tab already open in browser (not the origin tab)?

Much needed and exact replacement for old Live http headers, great ! Thanks !

Perfect for what I need. It provides simple HTTP headers and relevant info in a well formatted, easy to read window.
The option to save to a file would be nice, but still nice as is. Thanks for developing!

Oh, I was searching for a replacement of Live HTTP Headers and it looks like I've found one. I like the simple edit window with "Resend" ability.

A tip:
- add a "Auto scroll" checkbox and functionality

Http header live is a little simple,but it is working.I hope it will be better.
