I posted that link more than 30 hours ago.
80% still have no update.
As for me, I will wait on the overall revision to FF. I still have ie and oprea.
Or, if it will not crash other apps, you can change the date on your machine when the certificate is valid a few days ago. Reboot required.

Google, Microsoft and Facebook give lots of support money to have these browsers molded in particular ways (as well as other folks) and most of it is not in your favor.
I keep thinking someone is going to dev a good open source browser that is not beholdant to them. FF is OS but it has been fashioned in a way they prevents many forks. Think RedHat Linux.

I am doubting the story Mozilla is handing out and will re-think my choices in the future.

Face it, tracking has become a big issue now as it should have been a long time ago.
Anyone wanting to run software on my system without express notice and explanation of exactly what info will leave my system and who might receive that data can't be up to anything worth your while. I am not a experiment. This is NOT BETA.

They pipe a new version once a week at least. Wait for it.
