firefox palemoon waterfox baselisk problem, not on chromium

Hi, 
While browsing on stock updated Debian stretch I get several times a
day:

Secure Connection Failed

The connection to www.google.com was interrupted while the
page was loading.

The page you are trying to view cannot be shown because the
authenticity of the received data could not be verified. 

Please
contact the website owners to inform them of this problem.

---------------------------
I don't think  a message from me to google will solve this problem.

---------------------------
I get this message several times a day, for any website,
and the pages are not loaded.

Tried a lot of things I found on internet, most of them from several
years ago. None of them helped.

Disabled all my add-ons, did not help.

Reset my browsers in a maiden state, did not help.

By-passed my proxies, did not help.

Those sites all load OK in Chromium, but I do not like this browser.

Strange thing, when I retry 2-80 times the pages get loaded.

I use Tab Mix Plus Mozilla add-on to reload every 2 seconds until the
pages load.


In short:
Secure Connection Failed

Any ideas what can be the solution?

Thanks!
