keeps popping up a new tab on browser startup, nuisance anti-feature that can't be disabled
very good
Didn't work
does not work in brave linux at all, even the example
En tema oscuro no se ve cuando esta activado o desactivado, pero me ha sido muy util. Muchas gracias
Doesn't work for POST request, but it says for all requests. Waste of time
Thanks you for this plugin: I added a custom authorization header in my browser to login without going to the login page to enter email and password
awesome plugin! thanks a lot!
Very useful extension. Note: I need to change the Host: header to test a cloudfront setup before going live. That did not work in chrome, but it works with this same extension on Firefox. I suspect Chrome changed a setting that prohibits messing with the Host header ?
Used this for debugging OAuth X-Forwarded headers on local setups and works great, very helpful, thanks!
