hi, the open h264 plugin (provided by cisco) is part of firefox and won't be related to any page loading issues you are experiencing.

can you please be more specific about what pages you are unable to load and what's the exact error message you are seeing?

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.

This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.

Thank you both for your replys. W remote device won't accept the connectionhat happens is when I click on a link or even search for an adress I get an error mesaage that says " remote device won't accept the connection" However I can log in to g mail and face book and some web sites ok. Is it my router? I'm using a Cisco linksys, model no WRT160N V3. I'd be so grateful for help as I'm far waway from any city to bring my laptop and router into.Thanks again.
