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.

Изумительное дополнение! Позволяет автоматически загружать русскоязычные версии сайтов, вместо украиноязычных. Настраивается не сложно. Работает безупречно. Редиректы мгновенные!

I use this add-on all day, every day.

I use the same Extension in Google Chrome as well (obviously, the version from the Chrome Web Store).

It does exactly what it says it will and doesn't require much set-up (although there's a lot of inherent power in it if you understand things like Regular Expressions).

For anyone who's struggling to get it working, the Developer appears to be responsive and super-helpful on the "Support site" link in the "More information" section of the add-on's page at mozilla.org: https://addons.mozilla.org/en-US/firefox/addon/redirector/

As others mentioned before, it simply does not work. I tried it several times and double checked the instructions.
