I use this to redirect steam URLS to steam using
steam://openurl/https://steamcommunity.com.
It would be 100x better if I could close the parent page after the redirect takes place.

Simple and lightweight yet insanely flexible.

Nice and simple to setup, in certain situation as when doing some web development, it can be really useful. Thanks!

It just works. The example URL feature for checking that your expression matches as intended comes in really handy. Great little extension!

great little extension to redirect to the smile.amazon subdomain (my original problem this was intended to solve). there are of course addons to do just that, but ONLY that. while still learning my way around userChrome/Content and userscripts, this great little tool allows me to get the job done now while learning how to bake it in to my browser myself on a later date. thanks a lot! :)

Super easy to setup some URL redirects to replace images. Took me about 20 minutes. Great add-on!

Works the way I want. Its very small footprint gives it a big boost of points.

Powerful extension that can rewrite URLs Firefox wants to open on the fly. Even though the filter creator tries to assist, some understanding of regex helps a lot ;-)

Awesome for redirecting sites that have awkward translations to the English original.

perfect

bug:
"Enable notification" setting is not remembered when I restart Firefox.

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.

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.
