Need a new browser for older Macbook Pro

I have an older version of the MacBook Pro - ancient in computer terms. It is a 2006 Macbook with the 32-bit Intel processor, etc. It is upgraded as far as it will go in terms of hardware and software, but it is still stuck with the 32-bit system, which means browsers like Google Chrome no longer support it or send out security updates. If they haven't already dropped support for it, I imagine Apple won't be supporting my OS (Snow Leopard( anymore, either. 😟

The obvious solution is to buy a new Macbook, but I probably won't ever have the money to do so. This one still works just fine for what I need it for - email and Internet access for the most part - and (please don't throw stones 😝 ) I use my Windows desktop PC for work, gaming and everything else.

I am still using Google Chrome but I am looking into my options for alternate browsers. Are there any browsers for Mac that still support the older hardware and OS? (I think FireFox still does, but they seem to be heading the same way as Chrome and may not support it for much longer.)

I - and others like me - am probably running out of options and eventually will be stuck using an obsolete browser with security vulnerabilities, but I hope there is still a browser out there that will continue to get updates for older systems.

Suggestions are much appreciated.
