Interesting. I'd love to get something like this into things I use frequently. Primary issue for me is, though I often browse HN for example, I only do so using an app. Generally I rarely use the browser for anything beyond research and linked articles.
After a certain age many people, and I'm definitely one of them, stop using phones for anything serious. Too small screen, unreable fonts, or alternatively zoomed-out fonts make pages unreadable anyway.
So I'm basically back to using phones for, well, calls.. and a tablet or, if more than just casual, a real PC with a huge monitor if I want to actually spend some time on the net.
In short - I'm definitely now in the "browser for everything" group, I don't use apps if I can avoid it, and definitely not on phones.
You're absolutely right, we typically spend more time our our phones for most people. we're also preparing to port this feature to mobile, possibly based on the mobile version of Firefox browser.
