Its a great extension. However since this morning it has not been working.
Got it installed configured in less than 5 minutes. We have a production environment where the load balancer injects info into the header on each requests. To test those, we need to inject the same data from the browser (we do not run LB locally !). After testing it, I was able to extract the settings and distribute them to the whole team. I could not ask for anything better for my use.
Love it!
It's completely useless. It won't even load the rules page, saying I need to disable my ad blocker. Yeah, no.
I use a 4K display with Windows dpi set to 200%. Although many websites use a url based server side scaling model, few of them cater for high DPI desktop displays, so I usually see blurry images everywhere. With this tool I can manually correct those websites to improve my experience. Thanks!
I came, I saw and it did what I had to. Great!!!
Succeeded to intercept a request and modify its target where other extensions failed. Giving the response itself instead of another URL to fetch would be a plus.

Redirect feature is excellent! Helps me avoid distracting web pages.
Does what it says! Was hoping to see how other people use this extension to improve their browser experience. Is there some place I can do this?
