Works perfectly. Would be great to be able to do this per-tab instead of for the browser entirely, but does what it says it does.

good

The add-on work perfectly. Thank you.

I have tried CORS Everywhere this morning and it works perfect!. The user has to enable the pluggin prior to check the functionality

Simple and good addon for quick web development. Thanks

This app is Needs Update for Firefox Version 57.

Does not block anymore! It used to work, was there a bad update?
But well rated because it used to do the job perfectly, hope it'll come back soon!

Very useful, works as advertised.
The whitelist is not so easy to use (you don't just add bare URLs, you have to include slashes and regex flags, and the UI help is inadequate). But five stars anyway.

Easy to install and config the whitelist (useful if you want to apply this plugin just to some domains)

This is the best plugging for http request.

Very useful

I needed to test a web page on a local web dev environment, and of course CORS isn't allowed in firefox, so this extension solved it. many thanks to the creator. much obliged.

Does what it says and is a great help developing / working with CORS sensible APIs.
