I agree that this is less than optimal.  Could you point me to the bug
report you filed in bugzilla that requests these changes?

Here is one, you can follow the links to other ones :)

It probably isn't that hard. Why don't you write a patch?

I dont have any knowledge of programming.


Honestly though, this stuff is such a miniscule portion of overall
security...  How many users actually care when websites don't even have
valid certificates?  Heck, most browsers don't even check for CRLs by
default, including IE.

True, but the ones who would like to check, they find that it is impossible. And the ones who are not used to check it, take an example from Opera how to make them check it: It clearly displays the symmetric and asymmetric key sizes in the addresslike/statusline when you are in https connection. Also, it warns if the symmetric keysize is secure, but asymmetric is insecure.


There are many many more, much easier ways to steal someone's sensitive
info without attacking the crypto.

Sometimes. But that doesnt mean that obious weakness should not be fixed. Heck, why even bother patching at all, since the "weakest" link is "always" the dumb user who will execute any file you email to them...lets just forget Windowsupdate then, and new versions to Firefox, right? ;)
