I am looking for a secure browser for my 10 year old iMac running 10.6.8 (Snow Leopard). I know that the browsers I have namely Safari, Chrome, and Firefox are no longer supported. I am not happy that I would need to rectify this with the purchase of a new Mac as this one just runs fine and I would really like to keep it. Is there a solution such an app or add-on and if so please let me know.
