I use focus daily, but it’s not a daily driver.

It doesn’t to tabs, and links that the site forces to open in a new tab often don’t work. It also doesn’t do JS well by design.

I use Firefox focus for throw away links I come across, but for everything else I need a full browser

You can’t open a new tab yourself, but you can open it by long-pressing a link.

If you’re running in a Custom Tab on Android, you need to switch to the full Focus if multiple tabs are involved.
