I've run across a very curious issue - Web pages do not render correctly in either Internet Explorer (version 8, 9, 10, 11 - I've tried them all) or Firefox (latest version).
If I visit a Web page that contains a commenting system (Disqus, Facebook, etc.) none of the comments are displayed. Moreover, I've noticed that none of the Greasemonkey extensions (all JavaScript) that I've installed in Firefox run, either. I don't expect an answer to the Greasemonkey extensions issue, but I think it helps to shed light on the overarching issue. Something seems to be blocking JavaScript but I can't figure out what it might be.
I've a Windows 7 Pro box with both IE and Firefox as well, and everything works fine on it - all Web pages render correctly.
I'd greatly appreciate any suggestions.
Thanks.
