What is webutation.com other than a parked site for sale, what did you get from it. found it listed as an extension at addons with a homepage webutation.org which matches your add-on, but the website redirects to webutation.net not exactly reassuring. Similar extensions have had problems, in order to report on a site it has to get information from somewhere (each time?).

I see you have Skype which appears that it could cause some problems similar to what you have, but it is disabled when you posted.

Check your extensions against

• Problematic extensions - MozillaZine Knowledge Base
  http://kb.mozillazine.org/Problematic_extensions

You have other extensions that may not be listed as Problematic but that I would be very wary of.

Try starting in Safe Mode which can be started from the Help Menu "Ctrl+H" > "Restart with add-ons disabled" which will restart in Safe Mode for one time. See if you can get into your email sites and att.com

Hi, McRitchie: My 1st crack at replying to yours. a) Webutation gave me the app download, v1.0.2, via Firefox Add-ons, that's what Webutation gave me; and I must say, Thank you, for questioning my attribution to www.webutation.com; that was my (poor) memory, that gave me the wrong TLD - correcting my goof now, I agree with you, that site was www.webutation.org, not .com (neither was it .net). Accessing the More link in Add-ons gave me Mozilla's page that shows Webutation.org's rating 4 stars out of 5, and 14 reviews; and it displays the corrected, .org URL above for further information, and also a Check for updates link.

  This was what Firefox reported Distrust on, when the .org link was activated.  Firefox generated the "Untrusted Connection" page, and gives this in Technical Details: 

| www.webutation.org uses an invalid security certificate. | | The certificate is only valid for the following names: | | *.kasserver.com , kasserver.com | | (Error code: |ssl_error_bad_cert_domain) |

  It was this "kasserver.com" stuff that made me worry. I see that the peculiarities of webutation are working as a distraction from my main question, i.e., Why is this installation of Firefox v4.0.1 consistently changing (is redirecting the wrong term?) my plain-vanilla HTTP:// URLs addressing HTTP port no. 80, into Secure URLs using HTTPS://  and accessing Secure HTTP port no. 443??  There would not be a Certificate validity/invalidity problem, if this Firefox would let me connect to the websites without Certificates.  Please note: Webutation is far from alone in being unable to connect - - Firefox is reporting "Problem loading page"  also on these HTTPS connection attempts to major-major websites including Adobe.com, sun.java.com. Type in HTTP://java.com, hit <Enter>, and Ffx changes the address slot to https://java.com, and then, it cannot find the server, the server takes too long responding. One  thought - Is it Webutation that does this to Firefox? OK, I will disable Webutation and restart Ffx and see whether it repeats, and get back to you on that.
