In a blog post, security engineer Richard Barnes explained that most Firefox users aren't affected, and those who are can simply upgrade to the latest version of Firefox -- version 43.0.4, released on Wednesday -- to fix the problem.

"Since Firefox rejects new SHA-1 certificates, it can't connect to the server," he added.

The good news is that you can tell if you're affected by visiting Mozilla's security blog. If you are, you can upgrade from its website.

The bad news is that this wasn't exactly unexpected...
