How to reimport a distrusted CA

A while ago I pre-emptively deleted QuoVadis, not so much from believing they're strictly unsafe, but I wanted to be alerted every time it pops up. Now it turns out that a couple of sites I use often have QuoVadis and I'm tired of confirming exceptions for every subdomain.

1. Is there a safe and supported way of adding the CA certificates back?
2. If not, I've downloaded some PEM & DER files from the QuoVadis website. How does one go about importing them into the browser?

Thanks

If it's a built-in CA root you distrusted (which I'm pretty sure is the case here), then you can re-establish the trust with the built-in root in the certificate manager. You can't re-import them in that case because they were never deleted from the store (that's not possible for built-ins) but they were flagged as untrusted, instead.

To restore, go to Advanced -> Certificates -> view certificates, Go to "Authorities" in the certificate manager, and on the distrusted certificates use "edit trust" and enable the checkbox "This certificate can identify websites"

Thanks, worked like a charm! Funny thing, I had that page open but didn't find QuoVadis because for some reason I searched for Q after X :oops:
