I changed two things in my browser:
- All cookies but from a handful selected websites, are destroyed when I close the browser
- uBlock blocks now all 3rd party scripts and assets (like images) but a handful which I manually allow on some specific websites.
The question is not why you did this. The question is, why this is something new, that you didn't do a long time ago already? And maybe the third questions: Shouldnt this be a browser default?
It didn't came into my mind until I watched a YouTube video on advanced uBlock settings. Quite some websites use a different domain for their CDN, I know which implications it has to block it, but it's not really obvious why a video doesn't load or a button doesn't do anything.
