Should I use chromium based browsers or firefox? - lemm.ee

Chromium has better features, but with google announcing its plan to ‘drm the internet’ I 'm not sure if it’d be a good idea.

There are a lot of articles exposing each option. Personally I prefer chromium based browsers because they support full “containerization” of each tab.
I tried googling about Chrome containerization of tabs and found nothing. Can you elaborate?
It’s one of the main features of Vivaldi

Also isn’t that what Firefox containers do?

It’s not per tab, but I don’t see how that would be useful. I add specific topics and then make / destroy the containers as needed.

It’s already annoying enough logging into the sites per container, I can’t imagine doing that every time I open a tab.

This is the even better sandboxing. You can only give access to the groups container.
