Works.

Spot on ! I wonder why no other addons that does this simple job of replacing urls does it in a straightforward manner as this does. Kudos !

I wish I could say it is amazing, though. Unfortunately, I cannot. It has much room for improvements. For one thing, its UI is counterintuitive. I hit the "Add" button nothing seems to happen. I close the tab and reopen it to find out something may or may not have happened. There is no "Save" button either. Also, it is impossible to change the order of rules.

I was trying to define a rule that replace "countryOfOrigin=*&" with "&". I've had no luck so far.

Very easy to use! I am using it to watch YouTube shorts in the regular player!

It's as easy as entering:
www.youtube.com/shorts/* as the origin and:
www.youtube.com/video/* as the destination!

This is a very useful tool, I highly recommend it!
My only complaint is that it only seems to work when opening a YouTube link in a new tab (ctrl+left mouse button).

Works as intended. I'm now trying to figure a way to dynamically update this... or if you could provide a way to bulk update those settings, it'd be great.

По описанию именно то что надо, но увы не работает на firefox 72 (x64)
Написал правило https://yadi.sk/i/MKxk5UMIwWLrVQ но оно никак не работает.

EDIT: Fixed in 1.5

Since the recent updates the switch doesn't happen anymore; rolling back to 1.2 works.
