I would buy a Zenfone in a heartbeat if they had more than 2 years of support. Apple’s doing 6 years. Microsoft is doing effectively infinite. I don’t get why every Android manufacturer other than Samsung and Google seem so bent on producing mountains of e-waste.

I liked IceRaven, but it’s not regularly updated anymore. I would go with Firefox Nightly, since that lets you install any extension you want (through an arduous process), where regular Firefox only lets you install add-ons on Mozilla’s approved whitelist.
