After years and years of using Firefox, I decided to leave it and start using Google Chrome. Why ? Because Firefox returns error "sec_error_unknown_issuer" very often, when I access to my usual websites. Something must have been wrong with last Firefox update. Getting these SSL errors on every other site is starting to really get annoying! There is nothing wrong with the SSL certificates or the sites. It's your browser that is unable to verify the certificates.

When you fix it, maybe (only maybe) shall I return to Firefox.

Have a good day.

hello, this is most probably caused by external factors and a possible solution depends on different factors. please attempt to add an exception on the bottom of the error page & inspect the certificate (see the screenshot attached for instructions):
which issuer information does the certificate contain?

thank you!

"This Connection is Untrusted" error message appears - What to do

I did have this problem and I did remove Rocket Tab and the problem was solved!

Did try the removal of cert8.db. first a few times but it didn't work .
