How do I get latest browsers to work with older OS

i choose NOT to update my mac system from 10.6.8 as i see later versions as inferior or more tech dependent. also i do not know if some programs i use are compatible and do not want the hassle of having to reinstall update etc.

but many browsers are becoming unsupported. is there no program that will work on older OS that can act as a facilitator for updated browsers? if not someone should invent one. any other options available? thanks in advance.
