A great solution for, for example, customizing the display of a default sort order for comments on Reddit other than "Best". Unfortunately, setting up the rules requires knowledge of regular expressions, which is not something every housewife can do. I would suggest using something like the method used by the "Add custom search engine" extension by Tom Schuster as an accessible alternative.

Solid extension! Using it to redirect x.com to twitter to make the blueblocker extension work. Easy and fast setup

Excellent.

Although, the example doesn't work (needs https). I submitted an issue on GitHub.

Great addon! Wish it was more easier to use though! Used it to redirect reddit user profiles to gilded version on new.reddit.com since original reddit caused too many redirects! I had to look up the guide for the addon and "Redirect using query string parameter and wildcards" helped me!

Fixed the nightmare of logged out Reddit. This has been a curse on me for far too long. Thank you Einar.

Does exactly what it says on the tin. Easy to configure, simple, and straightforward. Thank you!

Take that, www.reddit.com!

perfect for what i need; still works even if it hasn't been updated in a while. I use it to veer away from my Twitter and Facebook homepages -- and it perfectly does the job!

An absolute marvel, extremely useful to remove redirectors from sites like Pepper (Dealabs pour les amis français :) )
Two things I wish to improve it even more : integrated sync of redirectors on Firefox and a "community place" where people would exchange their redirectors.
