I removed the fx3 content and fx35 tags, used the Template:clearCookiesCache and Template:OpenHistoryLibrary templates, added Fx4 screenshots. It needs review.

It has been in pending review since June 11.

Approved. Looks good. Thanks!

"CA Personal Firewall" subsection renamed "CA Internet Security". Replaced outdated link with link to "Cookie Control" article at http://cainternetsecurity.net/Kb/kd.aspx?KDId=1026

I approved it. Ready for localization?

The three firewall articles that are not archived are the ones about Windows, Norton 360 and McAfee Security Center. So I'd be tended to remove any reference to a specific firewall in this article.

I've already edited MozillaZine's article to note that the "Cookie Control" feature has been removed in recent ZoneAlarm versions so I was thinking to do the same in this article. See http://kb.mozillazine.org/Websites_report_cookies_are_disabled#Security_software_settings

Like you said, we're no longer maintaining Configuring CA Internet Security Suite or Configuring ZoneAlarm Free Firewall (we never had an article on paid/"Pro" versions of ZoneAlarm that included the Cookie Control feature.) Do you want to remove the entire section on security applications or just remove the two links?

If you just remove the links, do you want to say something like, Some Internet security and privacy applications have features that block cookies. Check the documentation that came with your software or visit the software provider's support site, to see if your application includes a cookie control feature and how you can change those settings. ?

I've made an edit to remove the two links and replace them with the above. Needs review.

I approved it.

In this good article antivirus conflicts are not taken into due consideration; after migrating from IE 6, I had Error 102 (net::ERR_CONNECTION_REFUSED) and couldn't get to a solution by following most common hints. I didn't had confirmed my subscription to Norton and I am using Avast; I was aware of conflicts, and disabled Norton without uninstalling it, believing it was enough, but only once I thoroughly uninstalled Norton, Firefox (and other browsers I was trying, all with the same problem) started working perfectly.

Hi vottrioolivati. This article is about errors while logging in to websites (i.e. when you need to enter a username and a password), not loading websites. If you have comments about error 102, make them in the discussion forum of Websites don't load - troubleshoot and fix error messages.

I just posted the following to the thread you started in the KB articles forum:

[...] the "slug" (found in the Description section when you edit an article) has "requrie" instead of require. I think all that needs to be done is to fix the slug but I'll add [ATTN: M Verdi] to the thread title, so he can review it.

If you can't log in to Gmail and you use a Google extension, try disabling it and then following the above steps to clear cookies and cache before trying to log in again.

What is Google extension? Is it Google Toolbar?

I don't know the context for that sentence, but I think it's referring to any Google extension that deals with Gmail (like notification add-ons). It could mean Google Toolbar too, I suppose.

Let's see if anyone can provide more context.
