Given that it is the best (and only?) addon that allows to redirect URLs, I have to give it the maximum score.
I use it to redirect to the english version of the websites while being abroad.

It would be even better if it wouldn't require scary permissions.
See:

The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords.

Does what it says it does.
Replaces some addons / userscripts for me.
Really makes my life easier.

I love this, it directs my facebook to the most recently posted (instead of having to click that on my news feed option) and automatically donates to my smile.amazon account. Thanks!

Thank you.

Amazing tool! It has all the options one might need, no more and no less! Very handy to redirect to the mobile version of Wikipedia on desktop, which is very clean.

Helps me forget that new Reddit exists.

A very helpful extension that quietly and consistently does its job, time after time. Thank you.

Trying to set this up but it won't replace the url https://i.imgur.com/fJEYjcl.png

Thank you for creating this great addon for us!
