The best in it's class extension. I would like to ask the author to allow contributions as I would like to help fixing some bugs.

Extremely convenient and well-executed

Does exactly what I have been searching for: during development, swapping out parts of a hosted application with files from the local dev server.

beautiful，useful，powerful

A great tool for modifying headers within the browser, now that I've stopped using ModHeader. Easy to use and a very clean way of separating different websites and environments/regions.

Minimal yet does what I need - being able to block requests on the URL level is a game changer. I've tried nearly every plugin to modify HTTP headers and this is easily the best.

I switched to this tool after ModHeader turned out to be full of malware and bugs, and so far, it's been great. It's simple to use and works well for my needs.

Started using this as a replacement for ModHeader due to the bugs and it seems great so far. Very easy to create headers and the folder and tabs make it easy to keep them organised.

This has become an essential tool in my daily workflow which I use this as both a developer and as security-conscious user. A perfect replacement for ModHeader which is now malware ridden junk.
