No problem, I try to speak only when something might help others. In such regard, as a final post on the subject, at the Chrome extension store I since have found an extension called “Script Defender”; it got very good ratings at a recent Wilders Security Forum topic titled: ‘Script Defender For Chrome’; I’ve added it to Comodo Dragon, took the six tests in Wilders topic link, and it passed; I next went back to the same site as last night with Dragon and NO homepage change this time…Script Defender at all tests gives no alerts, but just my setting it to simply block scripts/plugins caused a “silent fail” for the silent drive-by site!

The current Chrome “Script Defender” is free, version 4.0, and just came out updated a few days ago, and its tiny on system. I had to whitelist your site and Disqus to see comment icons/get into Disqus, but obviously I had no problems with Script Defender. It can also block iFrames and other things, but in my case Dragon/my layering actually does do all that and more. Script Defender has yet caused me no known conflict(s) with any legitimate Chrome plugin, OS, or otherwise.

Perhaps more well-advanced computer users could try out Script Defender, and if it’s as good as it appears to be it could be an option for anybody using Chrome or Chrome-based browsers; I long knew Chrome has CSS (XSS) issues, but thought Comodo has addressed them in its take on Chrome; this extension for me has closed the one known pinhole in my system armor. Thanks again for letting me share this!
