Born out of the adware thread: I was checking out my credit union site again today, a view source in IE shows it has this code:
(Oops, removed some brackets so it doesn't go boom, hopefully)
Now, in IE it does exactly that, displays a box showing the last 10 transactions for that account. There is a Savings0M further down the page with the info in it.
Any ideas if this is doable with Firefox, if the code is correct or if I need to download an extension to make it work?
There isn't much you can do yourself to fix it, other than notify them that it doesn't work outside of IE (in a friendly "this will make your customers happier" way) or report it to tech evangelism and let them try to sort out exactly what's wrong and contact them for you.
Call your cable company and ask if they recommend someone in a "Pay for support" model. If you are in luck, not only will they recommend someone who knows how to work with their setup, but you may get a promo rate from the referral.
