This does exactly what it says perfectly. The ability to use REGEX is extremely useful. I've created a rule that redirects YouTube Shorts URLs to the URL for the actual video.

Seems good and helpful, and uses the regex-"dialect" i am familiar with. Though I don't know it's name. 5 stars.
What I would find extremely cool, was if the URL modification patterns could also be applied on my bookmarks, so I would kind of "clean" them. Especially remove "trash" parameters of UTM campains or other unneeded GET-parameters in Social-Media URLs which prevent me from recognizing whether or not I have this page already stored in my bookmarks.
But likely not so little additional work to integrate this both concerning logic and UI.
Anyhow: Good extension, good work. Thank you!

Pretty good! I don't think it's regularly maintained now, but still, one of the best extensions to make me stay away from distractions. The patterns option is especially helpful if you know how to use it.

A very useful add-on. Thank you very much.

Works as expected. Super simple. Thank you Einar for the extension.

Great stuff. I use it to make logging in to certain sites faster.
Issue: 'Enable notifications' gets disabled when closing Firefox

I've been using this for a long time now, to redirect YouTube Shorts to actual videos. Easy to use, I like it.
Couple of issues, though:
1. It doesn't work when staying in the same tab - it needs either a reload or to open links in a new tab for it to kick in. Small issue really, since I almost always open links in new tabs.
2. It stopped working completely for me for a bit. Removing and reinstalling the extension fixed it, though.

Takes no action when it should and produces no error output. Simply broken

Super cool
