Solved Firefox displaying unsecure connection notices

[sofasurfer]

Last night my internet was running fine. Today on my Ubuntu installation firefox is displaying unsecure connection messages on most websites but not all websites. Chromium is working fine.
I went to my Debian installation and firefox is working fine.
Why is Firefox displaying errors on one installation and not on the other?

WOOPS!
I just went back to my Ubuntu installation and firefox is running fine again. Either the problem corrected itself of the problem was that a glitch occurred during the first bootup. Anyway, the problem went away. Well, not a totally wasted post. I learned to just try a restart if a problem occurs.
Feel free to delete this thread if you think it was a waste.
Thanks.

Most of the time expired certificates that say they are expired when they are not has to do with that the time in your os is wrong, which auto-corrects it self within a few minutes usually.

Be aware that a Firefox update from version 149.0.1 to 149.0.2 happened today in Australia.
