I just noticed that a content script from my extension (rut at document start) is not executed in reading mode. Is that expected, or am I missing some permissions?
That is expected, as reader is very special and you wouldn’t have the actual dom to interact with, and most content scripts shouldn’t be running either way. I think there was discussion on enabling add-ons to modify the output of reader mode or add functionality at one point, but I’m not sure where that was left off.
Any change to find the link of that discussion? I’m unable to locate one in bugzilla.
I’m sure there are many useful add-ons that could be used in reader more, for example:
This could be solved by introducing new permission.
Here’s the open bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1371786
