I would have to guess that your home page is pointing to one of the what's new pages from a previous Firefox release. Nothing to be concerned with here. You can change your home page to point wherever you'd like by clicking Preferences/Options->General and changing the home page option.

For the stop script history issue, do you know what web page is causing the issue?

Thanks Mandel for the response. I haven't changed my home page. It seems that something is causing it to look at the previous version. It has go to the new version twice tonight when I have gone back. Not every time though. The stop script issue I can't link to one site. It happens way more often than not from various sites. Thanks

I think I see what you're talking about. The page google.com/firefox actually states that your browser is out of date. I see the issue to. Thanks for reporting this. I've opened https://bugzilla.mozilla.org/show_bug.cgi?id=710542

This - http://www.google.com/firefox - is the old Firefox Start Page used by the Firefox 3.6 and earlier versions of Firefox, I don't think it is being maintained by Google.

Starting with the Firefox 4 version, Firefox is using a "local" Start Page with the address of about:home. It looks similar to the old Start Page, but it isn't exactly the same.

We see a lot of such posts.
