News Google begins disabling UBlock on Chrome for user have had it installed.

To be honest, I would now be able to more confidently install uBO lite on my relative's PC from now on.

Manifest v3 is a weird mix of security and advertising incentives from Google. But personally I can't imagine myself not using uBO in the future.
I'm using uBlock Origin Lite on Chrome, and it hasn't affected me.
uBlock origin lite doesn't work good if at all. At least it wasn't working on my relative's laptop last time when they had PC trouble. In the end had to install firefox and use ublock origin there. I have been a firefox user from the start so I have no problem with how google effectively went anti-consumer (they always were but this one hit the nail in the coffin) but can't say for the others.
 
My installed ublock origin is still working in Vivaldi Browser (Snapshot Edition ver. 7.2.3621.60), though the chrome webstore states that it the extension will be unsupported soon.

It was auto uninstalled in the latest Chrome browser (134.x) and I had to switch over to the Ublock lite variant. Opera 117.0.5408.93 is working with ublock origin without any issues as opera has a different webstore for addons and doesn't rely on chrome webstore.
