You took the CMOS battery out for a long time. This has reset your BIOS to default setting including the date and time, possibly back to 2003.
You should have changed the date and time in the BIOS before booting into Windows.
The security certificates used on your computer are newer than 2003. If you started Firefox or IE without changing the date, you have messed with the certificates somehow.
You can change the date to present time and see it it makes difference.
Download and install root certificates update from here http://www.microsoft.com/downloads/details...;displaylang=en
Then download and re-install Firefox.
Try the System Restore. if it can resolve your issues.
