I have an early 2009 iMac (24-inch). I pay all my bills online, but lately some of the companies I pay tell me they no longer support old versions of Firefox, Chrome, etc. I can’t update these because my computer is too old. I’m not crazy about Safari and using my phone or iPad isn‘t a great option either. but I may not have a choice. Any suggestions would be appreciated. I can’t afford a new computer yet.
