The latest change was hard to figure how works (bc of the new 'On/Off') but now i can close the window without modified headers be disabled. A must have for devs. 5*

Great add-on, GREATEST developer. Rated 5 out of 5 stars

Left a review saying that it wasn't working for me, got precisely the reply I needed ("Turn it on." Boy, I feel silly now.) Now that's service!

No longer working Rated 3 out of 5 stars

No longer working in the N-Europe when trying to access US video sites. Shame.

Open the main Modify Headers window and click 'Start' so the icon turns from grey to red.

Recent problem Rated 5 out of 5 stars

Last time I was in the UK (August 2011) this worked perfectly. It no longer worked when I returned, but I successfully reinstalled it. Minor nuisance.

It's a minor negative aspect to the great add-on: Due to the latest version, the add-on bar on the lower part of the screen keeps popping up despite removing the Modify Headers button and closing the bar.

This review is for a previous version of the add-on (0.7.1.0.1-signed.1-signed). 

This has been fixed in version 0.7.1.1

It works, but I need an easier way to turn it on and off. Or something like a whitelist for certain sites.

This review is for a previous version of the add-on (0.7.0.2.1-signed.1-signed). 

Version 0.7.1.0 provides an easier way to turn Modify Headers on and off.

Not works in Firefox 6? Rated 5 out of 5 stars

This plug-in is really good. After 2 years using, I found it cannot work again after my Firefox updated to the latest version. Is there any update for this issue?

Is there any room on the road map to include modifying response headers? I would deeply appreciate a way to delete all the no-cache headers to stop sites losing my form submissions when an error occurs (think of all the sites where you hit Submit, get some bogus error, then hit Back only to discover that paragraphs of typing and are all lost and you forgot to hit Copy before submitting, or that you've lost the contents of a complex form that couldn't be copied first).

Years pass and I still can't find a solution to this one.

Hallo Gareth
your Modify Headers is a must have for me for long time
when will you implement the Roadmap 2011# 0.7.5: HTTP request creation tool to support POST, HEAD and other verbs. ?
please could you implement creation of CUSTOM HTTP request verbs too?
Thanks Mark

Very useful add-on! My only request for a future version is a toolbar button that opens the Modify Headers window and/or Enables/Disables All.

This is available in version 0.7.1.0

Very useful addon. Please, make official support for Seamonkey 2.0.x series.

Kudos to Gareth for ModifyHeaders! It's a great tool & I use it a lot. I have a small feature suggestion: what about adding a (RegEx?) filter for each rule so that they do not apply to all your connections at once?
I find that when I modify the Host: header for instance that all the fancy http services like Gmail stop working :)
Kind regards,

Site specific profiles

I'm working on adding site specific profiles to Modify Headers. This requires significant refactoring, so please be patient.
