    Hi

    Some ads are embedded in the web page. For a lack of better words. They do this because the ad blockers work too good at blocking the other sites that presents the ads. So some ads are added to the web pages and they can not be blocked off. Thisl explains why some ads will never disappear and this may become a trend for the future- the advertising will be presented by the host site and then clients who advertise know their ads are always present to the viewer.

    Local Windows applications do not need javascripts. The Window updates do. Gifs and some videos and some links and some site interaction ( like forums uses or search engines in that page) will use javascripts. That is the downside to blocking javascripts.

    As a general rule, I have the javascripts off or blocked. Then when the site is not working properly I use the Mobile Code for adjusting it for a "customized site" Mobile Code and continue with the offerings of that site. The reason is that there are browser exploits and javascript trojans that will enter the PC and promptly infect it. Most of my browsing is in plain HTML- no scripts, no cookies, no referer, no GIFs, no ActiveX and no java. Boring yes, but very safe.

    Even the user javascripts can be used to block third party scripts and this makes for an extremely safe browsing with the javascripts enabled. The downside to this approach is very big- those features you often wanted in that site are now no longer available. So this is not a desireable approach either.

    The IE user does not have these easy to use options in the browser or quickly made changes that is available in these two browsers. The ZA Privacy and it's Mobile Code is a valuable security feature as well as enhancing the internet privacy for the IE users as well as for the alternative browsers.

    Interesting. Thanks for this. When you are blocking javascript, are you also blocking the other mobile code (scripts, embedded objects, mime objects)?

    Can you suggest somewhere I can go to learn about all this? It's all new to me, and I don't really understand what these objects and scripts are and how they are utilized by web pages. Thanks much.

    BTW If you are a FireFox user, and wish to modify the referer or some of the browser actions or web interaction or security or just tweak it, then typein the address bar about:config and hit enter. The framework of the FireFox is presented. To understand what this means and how to modify the browser , use this for a guide>

    What I usually do after installing the ZAPro, is do the addreses in the Zones and set a few items to my personal prefernces. Such as disable the server rights for the Trusted and Internet Zones and disable the antivirus monitor. Tweak the components listed in the Program list. Just some tweaks and personal likes.

    Then the Privacy is set to just some block ads and block third party cookies and nothing else. Then all security updaters and all apllications are updated. This includes the Windows update and the Java and Adobe and anything else on the PC. Then I have the basic required sites listed and I know there should not be any issues. Then I continue with the mail, forums, search engines and the usual favorite sites ( all safe sites). Once the basic site list is created and all applications and all my favorites have been used, then I set the Mobile Code Control and the AdBlocking and the Cookie controls to the most aggressive and securest setting. I know what I need is very useable and if I stray from the good sites off to the dangerous sites of the Internet, I am well protected.
