Cert Error Bypass for Firefox 4+
SkipCertError
Overview
This Firefox extension (for Firefox 4 and higher) enables skipping the SSL/TLS certificate error page, for specific configurable conditions, like self-signed cert or unknown issuer, by adding a temporary exception.
Description
Tired of clicks for adding certificate exceptions ?
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 untrusted.
This addon is a complete rewrite of MitM Me for Firefox 4 and higer. MitM Me was originally written by Johnathan Nightingale, and then maintained by Andras Tim.
Notes
-
Hidden preference (edit with about:config)
single_click_skip
, to stil get the certerror page, but skip it in a single click. -
SkipCertError won't skip the cert error page when, after an OCSP query, a "valid" cert turns out to be revoked. It won't notify either. (This is an unsupported condition for the time being anyway)
-
build instructions:
cd src; make
-
SkipCertError turns on the
expert_bad_cert
built-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
