With Firefox >= 33 I get the following error: TypeError: certDB.getRecentBadCerts is not a function

We experienced the same issue in Perspectives, see:
danwent/Perspectives#143

Our current workaround was to fetch the certificate in ProgressListener.onSecurityChange

Hi,

Would you be interested in merging a PR that allows Convergence to be built as a XULRunner application which exposes an HTTPS proxy? This would allow any application which supports HTTPS proxies to use Convergence. The code is basically working now in the Namecoin fork of Convergence; it wouldn't be hard to backport it to your codebase.

Cheers,
-Jeremy

Notaries work fine for me from a Linux client, but when I run the client in Windows 8, I frequently get "Connectivity Failure" reported by Firefox. In cases where this happens, the notary server's debug output says that it received no connections. Often it works for a particular site after I refresh about 10 times (in which case the cert is cached, the server does report a connection, and that site works until I clear the client cert cache).

Any idea what might cause this?

The readme says:

"Send IP along with hostname (for e.g. SNI and cert validation) and port, because same name can be resolved to different hosts in case of CDNs or round-robin-dns mirrors, which can have unrelated certificates."

From glancing at the server code, it looks like if an IP is received from the end user, the server connects to that IP (I could be misreading though). Does this introduce security problems if the end user's DNS has been hijacked by the same attacker that is doing a MITM attack?

Seems the Convergence UI is broken on Firefox 33 and higher on Windows. On affected systems, the logo in the toolbar button is blank, and when I go into the options dialog, all options are blank and the OK button has no effect. Linux seems to be unaffected.

Here is the output with logging enabled via about:config; looks like a ctypes symbol is missing.

Testing with Firefox 24 on Windows 8 (latest code from master), the Settings dialog shows no notaries, all checkboxes are unchecked, and clicking OK doesn't close the dialog. Firefox 23 on Linux Mint 15 works fine. The following debug output is displayed under Windows.

A quick Google suggested this:

https://blog.mozilla.org/addons/2013/06/03/compatibility-for-firefox-22/

"Fold NSPR and NSS into mozjs (for Windows) or libxul (for other platforms). If your add-on has binary components or you build against Mozilla code for other reasons, this is possibly important. I’ve already been contacted a couple of times about failed builds because of this."

Not sure if this is related, but it might be a place to start.
