I like how when I open a news article in Firefox on my phone, it’s so easy to open the same article in Firefox on my laptop. All I have to do is open a new tab and start typing the article’s headline in the URL bar, and the article will appear at the top of the suggestions in the drop-down. This works flawlessly.
(I know that Firefox has a “synced tabs” list, but it’s quicker and easier to do it the way I do.)
Funny. For me, it is the opposite.
The kind of browsing I do in mobile vs laptop is usually so different, I'd never cared to sync both.
