"will not work on any browser"  ??

this is likely due to bank of america either being blocked, whereas it cannot download a security certificate onto your system.

i'm not a mac person, thou i play with one here and there, what i suggest is to test the issue by temporarily disabling your anti-virals and scanners for this and that, that you installed on the mac and are actively running in memory. Also, if your FF has any addons&extensions, temp disabling them too.

the point with the above is to get a pure mac environment and see if your bank can connect.

Thanks so much for your reply.

Unfortunately, I am pretty much a 'computer dumby', so much of your kind reply went right over my head.

Not your fault, of course.

Thanks for trying.

yes, i'm not a mac expert either.

but there is something installed on your operating system that is negatively affecting all the browsers.

so i has elluded to having the anti-virus software disabled temporarily.

but you couid try a couple of things first.

can you copy and paste the link here that you are using to go to the bank?

if you are usinga bookmark, open its properties to copy its link
