>>>>Thank you and Viv for helping me understand the issue. I have never used to setting NoScript (even though I use FireFox) and will have to look for this setting. But is there a downside to setting this the browser to NoScript?

>>>NoScript is primarily a security tool: http://noscript.net/ It is a plugin for FireFox.

>>>The biggest effect you see as a user is that any new sites you visit that use any active content or scripting (which these days is most sites) are broken by default. You have to actively whitelist (approve) this content on sites. You can do this either temporarily (while your FireFox session is active) or permanently. I have *very* few sites permanently whitelisted.

>>>Already, a large percentage of attacks on a typical system are from compromised web sites that attack your browser if you visit them. I predict it will soon be the most prominent attack vector. Blocking scripting etc. on sites you don't explicitly trust just makes tremendous sense. You're automatically protected from any zero-day attacks that make use of any of these vectors.

>>I have added NoScript to my Firefox. So far no major headaches except when I go to a news article from my Yahoo portal I have to click several times to return to the main page. I notices that I almost always have to do something about the NoScript warning. Just something to get used to.

>Yes, I've noticed something weird with Yahoo and FireFox/NoScript. If I visit a page from a link on a Yahoo page, sometimes that new page appears 4 times under my Back button, even if I only clicked on the link once. I think the page may try to automatically reload itself if it detects Javascript is disabled, or some such. So, I'd have to click the back button 4 times to return to the previous page.

Exactly the same happens to me too, on Yahoo. And even in UT it happened a couple of times. Earlier today I was looking through some messages I searched and wanted to get back but clicking on Back was not working. I suppose that the page/message was loaded several times. I will check it next time it happens.
