Solved firefox 18.01 - (Error code: sec_error_bad_signature)

[alexm]

(Error code: sec_error_bad_signature) why does this error msg. pop up on some web sites?

That is FF warning of an issue with the sites certificate. Whether it is accurate or not I can't say. Can you provide an address so we can check it with our FF 18.01?

Have a look here, it is for an older version, but is still valid

Not the caution, if you get warned of a problem with a certificate, and choose to ignore it, you should be certain it is safe (and how can you be?)

you could install the web of trust add on, that will give you another indicator about sites and details as to why a site may be untrusted.

You might try starting FF in Safe mode to see if it is add-on related.

Open FF> Help> Restart with add-ons disabled
