Easy (and quite customizable too!) way to add parameters to URLs, if you can't/don't want to make a userscript.

works and it's open-source

unfortunately doesn't work

This add-on is perfect! I use it to redirect myself away from time-wasting websites.

Working great. If you have a site like youtube and you click a video/link and it doesn't redirect (or only works when you reload the page), you need to go to Advanced Options in your redirect, and add "History State" for when to apply it.

peak, really well made

not working at all

Works perfectly fine on Android!

better than making a whole new extension just to redirect one website
