@dnsprincess I use Firefox on desktop as my main browser, because I love the bookmark tree. I don't use the mobile browser though, seems very slow.
I use Opera instead on mobile.
However, I also use Opera synced both on desktop and mobile with a separate persona. I find it syncs well accross devices so I use it for casual browsing, twitter, news, telegram etc.
Edge, I don't go there. Neither do I touch Chrome.
