Hi

I recomend that you install an add-on called Certainly Something (published by Mozilla). When you are next on a page and get this error message, tap the little padlock icon near the address bar and take a screenshot that you can append as an answer to this thread.

This add-on will provide the certificate information and will hopefully help us to find a solution for you.

Thank you. I am not fully certain what helped it. Either installation of the addon or it fixed itself over night without an update. But it seems like google etc. are back to normal again.

Hi

I think it was possibly an update, but it is great to hear this has been fixed.

Thank you for letting us know.

Just curious, does the Certainly Something extension work for you? Here I don't see the icon in the URL bar (anymore).

Aaaand it's back. I still can't seem to find any info about the cert, even with the addon. Edit: I just found out that I am having this problem only while being connected to my wifi.
