So. why are there safe browsers and unsafe browsers?

It all boils down to something called SNI, short for Server Name Indication, which is something older computers such as Windows XP and Android 2.x do not provide support for.

SNI allows multiple SSL-enabled websites (online stores, for example) to be hosted on a single shared IP address, which saves on costs. IP addresses are in short supply: there are fewer IP addresses than there are websites. The math is simple: if we want the web to keep expanding, we have to host multiple websites on single IP addresses and reduce our IP address footprint.
