Bug 1648615

Created attachment 1504265 [details]
certificate presumably of https://www.google.com/ that does not get recognized.

Description of problem:

nine times out of ten when I open firefox it goes to a page saying "your connection is not secure" when visiting https://www.google.com/
If I hit alt-home to go to the home page (google) about ten times, on the
tenth time approximately it will load google successfully.
Then it works fine for a few times.  If I launch a separate instance
of the browser it works okay.  Then if I close firefox and
do not use it for a while it goes back to the original state of not working.

Version-Release number of selected component (if applicable):
firefox-63.0.1-5.fc29.x86_64

How reproducible:
as above.  leave the web browser not running for a while then start it up.
very frequently happens.


Steps to Reproduce:
1. start web browser, assuming home page is https://www.google.com
2. 
3.

Actual results:
Your connection is not secure

The owner of www.google.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

www.google.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown.
The server might not be sending the appropriate intermediate certificates.
An additional root certificate may need to be imported.

Error code: SEC_ERROR_UNKNOWN_ISSUER

clicking on SEC_ERROR_UNKNOWN_ISSUER gives the certificate shown
in the attachment.

Also firefox takes a long time to load.
Could have something to do with cookie settings.

Expected results:
prompt startup of firefox and load google homepage.

Additional info:
see attached certificate.
There are tons of error reports on the firefox website pertaining to this.
looks like jscher2000 does not think something is wrong and thinks firefox
is configured incorrectly, but lots of people were complaining about this.
Note:  I noticed that very briefly when firefox loads up, it flashes on the
screen one of those firefox home pages that you get when you first install
or upgrade firefox.  Since this is a recently upgraded fedora from 28 to 29, 
I thought maybe it was getting stuck on that page (sort of like a 
splash screen after the upgrade).
