Since I must stick with my OS X 10.5.8, should I uninstall Firefox 16 and re-install Firefox 15.0.1?
Or, since both have security problems for OS 10.5.8 that Apple refuse to acknowledge (their way of forcing us to upgrade - very Microsoft-esque!), should I just switch to Safari or Chrome, both of which I hate. I really want to stay with Firefox. How much of a security risk is it? For comparison purposes, how much would the upgrade to 10.8 cost in the US (I live in Ireland), please?
All and any help would be much appreciated - thanking you in advance.
