Be careful with old versions!

These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.

Version 2.2 41.5 KiB Works with Firefox 3.0 - 56.*

Fixed issue starting with Firefox 51.0.1 where the Content-Type header was being duplicated on POST requedsts.

Version 2.1.1-signed.1-signed 41.4 KiB Works with Firefox 3.0 - 56.*

* Improved parameter handling
  • The parameters list is now automatically populated when viewing requests in the history.
  • The parameters and URI are now synchronized. Adding/modifying parameters in the list automatically updates the parameters in the URI, and vice-versa: if you add/modify the parameters directly in the URL they will be reflected in the parameters list.
  • You can now move parameters up or down in the list, and the URL will automatically reflect the positioning.

* Can now directly edit Header and Parameter names and values in the List. Simply double click to edit the field.

* Multi-select is now supported in the History view for deleting multiple transactions, as well as selecting multiple transactions to copy-to-clipboard.
* Multi-select is also supported in the Headers and Parameters list for deleting/reordering multiple selections at one time.

* Fixed: PATCH method was not working.
* Fixed: couldn't execute custom Methods from the Raw Request dialog
* Fixed: Response pane would not update if empty contents were returned for an XML/JSON response.

Version 2.0.1-signed.1-signed 39.6 KiB Works with Firefox 3.0 - 35.*

New features
* Added option to display responses in an embedded browser.
This works well in conjunction with the 'XML Pretty Viewer' and 'JSONView' addons. The embedded browser will utilize the nicely formatted displays that those addons provide.
* Added option to pretty-print JSON and XML responses.
* Added resizable sections to allow individually resizing the request and response areas, as well as the Response Headers and History.
* Added Authentication button to allow for entering username/password for Basic Authentication. This will ensure that the appropriate Authorization header is sent with the request.

Other improvements
* You can now set the timeout value to determine how long to wait before the request times out (Default: 30 seconds).
* Improved the styling for section headers.
* Added PATCH to the default list of HTTP methods.
* Added tooltip text for request URL list item.
* Fixed: extra newlines were being being printed for View Raw Transaction causing it to appear double-spaced.

Version 34.0 KiB Works with Firefox 3.0 - 33.*

Replaced status-bar (addons bar) icon with a toolbar icon. Toolbar icons can be placed anywhere by right-clicking and selecting "Customize..."

Version 35.9 KiB Works with Firefox 3.0 - 27.*

1) Via user request: added ability to add custom methods to the list of
available HTTP methods. Useful for adding things like PATCH (now a Proposed Standard -- RFC 5789).
To add new Methods: enter "about:config" in your URL bar. Then filter on:
Double-click the value to modify it. You can change it to a list of comma-separated values like: ["PROPFIND", "PATCH"]
You can also add read-only custom methods too (these methods will not send any entity body) via

When you bring up HTTP Requester it will show those values in the HTTP method dropdown for use.

Version 34.2 KiB Works with Firefox 3.0 - 10.*

1) Fixed: Parameters added to the parameter list were only being added to the request URI for GET requests, and not for POST/PUT/DELETE.
2) Fixed: Parameters added to the request URI were not added correctly if the URI already had existing URI query.
3) Fixed: When clicking Parameter Body to move add parameters to the body content, the parameters were still being added to the URI as well.
4) When viewing raw request, response is now separated with a "-- response --" delimiter to aid in readability.
5) Fixed: when executing raw request, was including the response content as part of the PUT/POST body

Version 34.3 KiB Works with Firefox 3.0 - 8.*

1) Added a "Find..." function in the Content Response area and in the Raw Transaction view window. Press the Find button or hit CTRL-f to search for text anywhere in the request/response. CTRL-g will do a Find Next to locate the next instance of the text that was last searched for.

Version 34.0 KiB Works with Firefox 3.0 - 6.*

1.0.2: (06/02/2011):

1.0.1: (05/23/2011):
1) Added a "View raw transaction" link in the Response area to quickly let you view the entire raw request and response.
This is the same behavior as double-clicking a transaction in the transaction history list.

and a tooltip will display the full value.

1) Updated to work with Firefox 4

1) History list now shows elapsed time for all requests
2) Double-clicking a row in the history will show you a raw text version of the request and response
