thank you , this is awesome. took a little work to get a working redirect, but the help-link was useful.
Required a restart to work.

Defaults to "wildcard". In order to use regex, change pattern type to "regular expression".

I tried to setup a rule with:

from=^http://www.youtube.com$
to=http://www.youtube.com/feed/subscriptions.

Firefox complains that there is an invalid inredirect. I removed the rule, disabled and uninstalled the extension, but the invalid redirect persists, even after a restart. My installation is broken :(

It does what's expected and has intuitive settings. I am happy!

doesnt work

Заменяет url только в адресной стране, если будет встречаться в коде страницы, замены не будет!

Works great with the simple rules I want for mobile sites I don't ever want to see on desktop. I typically leave more complicated rules to uBlock Origin, but it's nice to know I have this quick n' simple interface for that too.

Das Addon funktioniert hervorragend. Mit älteren Versionen vom Android Firefox auch.
