Both are made by the same great person (gorhill), and he discontinued uMatrix because uBlockOrigin’s “Expert Mode” already covered almost all the old uMatrix functionality!
I definitely know I’ve read his posts about it over the years(, but couldn’t re-find his specific discussions to link you to).
I think once you enable the uBO’s “Hard Mode”, you can get a more complicated grid UI + access to many of those bells and whistles.
Or, you can always go into the text version of “My Rules” and put in specific lines. Like:
Since I was never a uMatrix user, I didn’t pay too close attention whenever it got brought up.
But if the dev himself said uMatrix was completely superseded (okay, 99% superseded) years ago, I’d trust him.
Complete Side Note: One of my favorite Filters ever is making all embedded Youtube videos click-to-play.
If you put that into uBO’s “My Filters” settings page:
||youtube.com^$3p,frame,redirect=click2load.html
||youtube-nocookie.com^$3p,frame,redirect=click2load.html
instead of seeing a Youtube thumbnail + player, I:
- see a blank white box with the URL in it (which I can copy/paste).
- can click on the box to load the video.
I learned that trick back in 2021 and have been using it ever since:
I even expanded the same trick to support Vimeo, Scribd, and Soundcloud embeds too:
||player.vimeo.com/video^$3p,frame,redirect=click2load.html
||scribd.com^$3p,frame,redirect=click2load.html
||soundcloud.com^$3p,frame,redirect=click2load.html
Now NOTHING loads without my express approval!
And if I think it sounds interesting, all it takes is a little click and the video/file loads like normal!
