After the 26-10-2023 update, the extension stopped working

Can you test the newest version and test it out until the stores get updated with 1.3?

I just tested it and it's still the same. Here in Brazil it is 10/27/2023, 11:20am.

Something to report to you, I don't know if this helps anything. If you use YouTube in private windows, it takes a few seconds to load, but it works!

Are you using 1.3 @lexscs?

[lexscs]

Yes, and yesterday I even looked here to see if there was a new update. But I noticed that other users are also having the same problem!

I'm sure a certain adblocker (whether in-built or external) is acting up. FadBlock working in a private window also confirms that statement as extensions aren't available to the incognito mode by default. And by using the word "private", I suspect you're not using Chrome (Firefox and Brave for example have in-built adblockers which are also getting detected).

I installed the extension in Firefox as I couldn't find it in Opera. I have Chrome, but I use it for other things. I will check this question about Firefox adblock, thanks
