Hi I´m using Firefox 40.03(latest ver.). I have often had problems with google search-page that comes up with no encryption etc. I checked the adress and found that the fingerprint was false(tested via GRC). Should I delete the certificate?(guess I should). Under Advanced Panel, "show certificates" I have the following certificates which all are outdated exept a few. On the other hand it says the "life-length" of them all are set to "Permanent". Should I delete them all? Here they are: Server certificates: They can NOT be verified according to Firefox Diginotar: Cyber CA (2), Services 1024 CA, Root CA (2025-03-31) Diginotar B.V.: PKloverheid Organisatie CA- G2(2020-), PKloverheid CA Overheid en Bedrijven Entrust.net: Digisign Server ID - (Enrich) Equifax Secure Inc: MD% Collisions Inc. (http://www.phreedom.org/MD5 GTE Corporation: Digisign Server ID (Enrich) The following server-certificates are outdated and could not be verified. Under "details"-tab it says they are all bogus(...token) The USERTRUST Network addons.mozilla.org global trustee login.live.com login.skype.com login.yahoo.com(1,2,3) mail.google.com www.google.com All of the above certificates(9) was due 2014-03-15 Iguess I have been compromized. Never used google-mail or live.com but do use yahoo-mail and there have been issues. I guess Skype came with Win 8.1(preinstalled?) but I never tried using it. Addons.mozilla.org: Yes I have Skype Click to Call installed but I never did the installation. It is inactivated by Firefox I guess(see above!). But strangely this add-on can not be removed. There is som slanted light yellow lines across the add-on name etc. How to remove it?
