Same here, had to disable

I visited bbc.co.uk about 20 minutes ago, and started getting requests which apparently came from the BBC asking me to allow an Apple ID SSL certificate. I wonder if this is why.

It was asking me which SSL client cert I wanted to present to identify to beta.bbc.co.uk. In my case I have my StartCom one and a OSG science one.

Yep I got this too, beta.bbc.co.uk 443 cert etc.

No other site would load either until I disabled the extension.

I actually just had to disable it an hour ago, It wouldn't let me go to any website.

And then I found this article...
