Created attachment 666322 [details] [diff] [review] Patch v1 The implementation of nsPgpMimeProxy.cpp assumes that there is only 1 instance of nsIPgpMimeProxy (and its corresponding JS object). However, this assumption is wrong, as can be shown by selecting multiple PGP/MIME messages. The result is that Thunderbird crashes on all platforms if the JS Object is registered. The attached patch changes the single instance (service) type of nsIPgpMimeProxy to an object that is created individually for each message.
