simple-modify-headers

April 2025: doesn't seem to work anymore... I can't get any Header to be added or modified. Too bad

Set it up and forget about it. No ads!

add resource type feature also

it works! and free. thanks!

The results were precisely what I needed for my testing purposes.

It works and is simple! I had a problem with an old web app that doesn't work when the browser is in a language other than Spanish, but I didn't know it. I used ChatGPT, and with it, I figured it out. GPT suggested I install an extension to modify the Accept-Language in request headers, and this is the one I used. Now, the web app works as expected.

It works, OSS rules!

Perfect and open source !

good

This now breaks YouTube.
