Works like Postman Rated 4 out of 5 stars

Very similar to Postman.
Thank you dev :)

No longer works with Firefox Developer (v52.0a2) Rated 1 out of 5 stars

Great addon. Super easy to use and very flexible. It, unfortunately, stopped working with the latest beta channel release of Firefox. If not updated, will probably stop working with the release channel within the next few months.

Constant 100% CPU usage Rated 1 out of 5 stars

I've been wondering for a long time why my Firefox was a CPU hog, keeping a constant around 100% CPU usage, while IDLE, on OSX's Activity Monitor... this addon was responsible of that.
Once disabled the CPU usage dropped to 8 to 30 percent.

To the author: whatever you do with other people's CPUs must make sense, should be disclosed publicly and be ethical. At least 2 of those are not happening.


Works great Rated 4 out of 5 stars

Use this add on quite a bit. The only thing I would love to see is support for SOAP requests/responses.

Good but flawed Rated 2 out of 5 stars

Used to use this add-on for testing API integration in multiple projects, then today I experienced a client side bug that streams content as application/octet-stream instead of application/json, making the WEB API 2 project come up with MediaTypeFormatter errors.

Dismissed the error as a clientside error for hours, now it seems that its working fine from other clients. I regret making this assumption, now my faith in this add-on lies shattered.

Possible flaw in put/delete Rated 5 out of 5 stars

I still rate the tool as 5 stars, however there is a problem:

after enabling CORS on my server, PUT and DELETE requests are never sent.

The options request is sent, and my server returns 204 no content as recommended by NGINX documentation.

Instead of then continuing request, HttpRequester stops there, so this is obviously a flaw unless i did something wrong. After an OPTIONS request, the Http Agent is expected to then perform the actual request right?

Content length shows 990, but there is no body returned? I don't understand why. <-- image here

Must have for me! Rated 4 out of 5 stars

My only complaint is that the pretty format doesn't work which makes finding data within a complex json structure very difficult.

Tools recommended Rated 5 out of 5 stars

Plug-in already very perfect, the authors consider add something such as postman black skin?
This highlighted for programmers configuration, use more convenient, the plug-in skin color white, too boring!

Wonderful tool Rated 5 out of 5 stars

I use this tool to test my REST-calls from the back end. It's really easy to test all sorts of methods (PUT, GET, POST, DELETE, ...).
The only downside is the save dialog. Because you can't see how you named your already saved calls.

Rated 4 out of 5 stars

its alright with a few bugs , but the same functionality is already build into the firefox developer tools under network tab

Rated 5 out of 5 stars

Simple tool for simple checks. Works like a charm!

Works also with seamonkey 2.39 Rated 5 out of 5 stars

Simply extract the xpi, change RDF:Description in install.rdf to em:id="{92650c4d-4b8e-4d2a-b7eb-24ecf4f6b63a}" em:minVersion="1.0" em:maxVersion="20.*", re-zip as XPI, install, install customButtons, create a custom toolbar button, name it HttpRequester, paste in this button code:

var windowManager = Components.classes[';1'].getService();
var windowManagerInterface = windowManager.QueryInterface(Components.interfaces.nsIWindowMediator);
var topWindow = windowManagerInterface.getMostRecentWindow("window:httprequester");
if (topWindow) {
try {
} catch (e) {}
} else {
'httprequester-' + (new Date()).getTime(),

There you go! :) Works a treat.

Simple but great Rated 5 out of 5 stars

A very simple extension. Does exactly what I expected. Highly recommended.

Will it support x-www-urlencoded, form-data parameter? Rated 4 out of 5 stars

Just as the title says

Great, simple extension Rated 5 out of 5 stars

Very useful.

bad POST Rated 4 out of 5 stars

Вместо POST шлет GET.

Rated 5 out of 5 stars

Excelente, melhor do que o postman do chrome, neste consegui enviar um POST JSON sem nenhuma dificuldade nem configurações extra.

You can add more features Rated 3 out of 5 stars

Yea good one. But postman in chrome extension has more features than this. Postman has the feature to view our response as script. And also have the feature to view the methods in different programming languages.

Great Extension Rated 5 out of 5 stars

This extension is really great for mucking around with APIs. Easier than curl, etc.

Rated 5 out of 5 stars

Amazing! Thanks for this extension! It's a simple interface and work correctly with REST APIs.
