@[email protected] OK, I tried them. They are nice to have, but for users who manage many tabs at the same time. It is not my case.
One thing I like a lot about Firefox is the about:config page. My main change is content.notify.backoffcount > 0. It stops the browser partial refreshes, and shows a web page only when its parts finished loading. In my experience, it makes the browsing faster and more comfortable for my eyes.
It could be a nice switch to have in Vivaldi too.

Firefox does not have tab groups or workspaces (yet?) but you can mimic the experience with Sidebery.
