Skip Cert Error 0.4.4.1-signed.1-let-fixed.1-signed Requires Restart
This Firefox extension enables skipping the SSL/TLS certificate error page, for specific configurable conditions, like self-signed cert or unknown issuer, by adding a temporary exception.
About this Add-on
This addon won't survive e10s. It should be re-written from scratch, probably after the Convergence addon.
I can provide guidance to anyone interested in developing it.
Tired of clicks for adding certificate exceptions for sites with a self-signed certificate or issued by a unknown CA ?
After letting Firefox show it's built-in certificate error page, SkipCertError will add a temporary exception, and notify you unobtrusively.
There are very few self-explanatory options, which include the conditions of the error bypass. For now, few are supported: self-signed, issuer unknown, issuer
This add-on is a complete rewrite of MitM Me for Firefox 4 and higher. MitM Me was originally written by Johnathan Nightingale, then maintained by Andras Tim.
- SkipCertError won't skip the cert error page when a "valid" cert turns out to be revoked after an OCSP query. It won't notify either.
- SkipCertError turns on the
expert_bad_certbuilt-in preference, which enables adding a cert exception in 2 clicks (in FF4+).
- There are interesting arguments about FF's policy regarding self-signed certs on Johnathan's blog
