All extensions disabled due to expiration of intermediate signing cert

I’ll still keep using Firefox since I recognize the importance of browser diversity and the hazards of a Chrome monoculture (that and vertical tabs), but, yikes.

Still, this type of oversight seems all too common even in large companies. I remember several cases from Fortune 500 companies in the past few years alone. What would be a good way to automate checking for them? Has anyone developed a tool designed specifically to avoid certificate expiry disasters?

LetsEncrypt renewal is supposed to be automated. [1]

I know of a company that hosted blogs for thousands of customers. They used LetsEncrypt, but the CTO considered automatic renewals a possible security risk, so they did it manually. Problem is, the expiration happened in a weekend and they "forgot" to update the certificates before that. Suffice to say that the next Monday wasn't pleasant. They automated after that.

Some shared hosting like Bluehost now provide LetsEncrypt by default for all their sites with auto-renewal (But I don't recommend Bluehost shared plans for anything even closer to serious hobby due to absurd downtimes like most other shared hosting).

I used manual renewal for LetsEncrypt for about 4 websites on other shared hosts & renewing them every 3 months was a pain; had to keep reminders and schedules just not to miss renewals until I synchronised their renewal schedules to batch (manual) renewing them.

I had automated renewal for 1 website on a cloud server, it was a one time effort, I never had to bother about SSL cert for that site and the most favourable of them all.

Another option is using a Web Server/Reverse Proxy that supports Let's Encrypt automatically, like Caddy [1]. I believe Apache HTTPD has partial support [2], too.
