FWIW I'm not seeing that WebExtensions error in logcat, and I also don't see any change in behavior (I don't see any reader mode) when I'm connected using Mozilla VPN. (Though maybe that just means my network characteristics aren't the same as yours, with respect to the race condition that you're seeing).
I *do* see this error in logcat when I type the reader mode icon, though:

This seems potentially-related to the error in comment 5, given that it has to do with `handleMessage/receiveMessage` for reader view, with comment 5 being apparently about an undefined/unexpected `message.id`.
