I did the modify of the .rdf file so I could install this add-on in Tbird 2.0.0.16. "Find Message-ID" context menu entry is not shown when right-clicking on a message in the header list pane. Shows up only when right-clicking in the body of a message (message view) or the Message-ID header in the header pane of the message view pane. Okay, I get that, you have to get the message to then find out its Message-ID. However, "Find Message-ID" doesn't work when right-clicking in the message or source views of the message. You get the context menus for "Find Message-ID" but nothing happens when you use them. Right-click on a message header (after retrieving it) doesn't show the "Find Message-ID" entry in the context menu there. You have to right-click on the Message-ID header and then use "Find Message-ID". So I got it working under a specific usage. Then I went into its options. It lets you select a default search location (I want to use Google Groups to provide a URL that anyone can use to see the post). What's the point of configuring a default location when the context menu never lets you use one? You still have to select a location from the context menus. I'd also like a means of deleting some of the minimal selections, like Google DE.
