Not OP, but Zen is very good. So good I now rarely use any Chromium based browsers.
Is Zen not on Chromium?
Will I be able to install Chrome Extensions on it?
It is Firefox based, as for extensions no, it uses Firefox store, but popular extensions(like u block origin) are usually published on multiple stores
It is FF based. I use Downloadstar to scrap lectures. Chromium does not have one.
