Awesome. And a nit. Rated 5 out of 5 stars

Great productivity. Stable. Responsive Author.

However, just went for a spin with GMail Conversation View - https://addons.mozilla.org/en-US/thunderbird/addon/54035/ - and bugmail doesn't interoperate with it. Per Protz "I'm [not using] the message reader, so the bugzilla helper is probably doing this stuff in the background, it's just that it's another part of the UI that's displayed, the one that has the bugzilla status bar is hidden. [Bugmail needs to] overlay in some other part, so that it actually shows up even when the conversation view is active. Plus, I'm interfering with the message load process, so he would probably have to take that into account"
