Header Editor

Works as expected and actually is spam-ad-free, it's open source on Github. Thx. I am coming from "ModHeader", which nowadays is contaminated with spam, ads and silly decision, just a crapware now.

This does exactly what I needed it to do, I force some mobile website on desktop

Only feature I was looking for in this add-on was to overwrite the body response. However, and even though it's only supported in Firefox, that doesn't even work there with the current version of it (102.14). Submitted a support request in their add-on's github and got no reply after a full month of a wait. May work well for other features the add-on offers, but then there are plenty others which I'm sure would be easier to use as the UI of this add-on is not the most intuitive anyway.

Good extension, unfortunately not as good as the firefox version due to Chrome's limitations. For example, you cannot edit the cache control header prior to entering chrome's processing pipeline to fix websites setting bad cache parameters that force full page reloads unnecessarily. But this works on firefox.

works for my purpose of changing accept-language of localhost. Thanks!

Works fine when you're trying to modify request headers, but at the time of writing this, the extension is unable to edit response headers. Is there an explanation for this behaviour?

Good extension which can modify Authorization header on specific domain, which is exactly what I need

This does exactly what I needed it to do: let me modify the "Host" header when accessing my local development server so that I don't need to mess around with my "/etc/hosts" file.

good

Not easy to use if you want to test something easy and quick.
