Works and is practical.

Very useful addon to control the referer header when a server block the access giving code 403.
I had a big problem that I was unable to resolve playing with the html5 players templates itself.
Because the referer header is forbittnen to be changed inside the player.
This does the job actually well. Mo more code 403.
Used in addition to the CORS Anywhere addon allow me to get control of my player.

Fixed Pixiv not showing any pictures for me. That site has a separate domain (pximg.net) that serves all its images, and delivers a 403 Forbidden if the referrer does not contain pixiv.net. (target domain: pximg.net, origin domain: pixiv.net, keep)

Had to reset network.http.referer.XOriginPolicy in about:config to 0 however, as it seemed to interfere. This plugin provides the same functionality, thankfully (any domain: remove).

Very useful to get around dopey referer-based access restrictions on some websites

worked very well on pixiv.net when I'm using privacy-oriented configured firefox! Thx!

Having just started messing with BURP and noticing how this data was being sent multiple times with each page loaded I immediately went looking for exactly this.

I was considering taking the time to learn coding if I had to to get something like this if it didn't exist so thanks for time saved my man.

Cannot hide referer FROM a specific website. It only hide TO (target).

Installed on Waterfox Classic 2020.06 (56.03), despite that it's flagged as incompatible in the browser's addons page, it's working fine ! I just had to add a domain rule and save the configuration to get it to work.
Waterfox has an option to tweak the referer but it's too basic for my needs.
Thanks you very much for your work, I'm so glad i found this great add-on !

Tested here: https://www.darklaunch.com/tools/test-referer

Add a button to the panel, with the transition to the settings. It is possible even without an icon, all the same, its majority in the extended menu keep will be.

Fantastic! Working as it should.

Works well, but it is a bit unpolished.
