Tridactyl is a wonderful piece of software. My problem is the assumption that it’s unacceptable for an extension (which has a native messenger) to have the capability to modify Firefox when explicitly told to by the user. I use tridactyl, and plenty of people do, but realistically, the entire audience of an extension that gives you vim keys is highly technical, and can be expected to read the docs. Making the software edit personal files on disk when not asked to explicitly by the user is a breach of my trust model. It’s not as though fixamo is run on startup, it’s something you have to do explicitly. I’ve never run it, nor do I use the native messenger. This reviewer is totally out of order as far as I’m concerned.
