For some unknown reason, links at the top of my Firefox window have become unexecutable (i.e. non-clickable) - even links that are located further down the page become non-working after being scrolled towards the top. I noticed this after updating to the lastest version of Zonealarm. I've since uninstalled Zonealarm and am currently using Online Armor, but am still having the same issues. I have even uninstalled and reinstalled Firefox to no avail.
For what it's worth, links located at the top of my Internet Explorer window work fine.
Any insight that could be provided is welcome - thanks.
