Is there a way to configure Firefox either through an add-on, plugin, or other setting that will either reject or warn whenever it encounters a certificate that has been signed using SHA-1?
1 Answer
If you want a warning you could use various Firefox plugins:
- SSleuth It shows a value of how secure your connection is - SHA-1 leads to low score.
- CipherFox Similar, but warning not very prominent.
- CipherFox Secure Fork of the above with more features.
