"It requires your permission to: Access your data for all web sites"

I wish Firefox had a permission along the lines of 'Access all data from pages on which I activate the extension', which is presumably all this would need.

It also needs data when you click on a link it created in the past, which there's no real way for it to know in advance. (It could possibly use a custom protocol but it would break backwards compatibility with HTTP which would be a big downside)

As yoklov said, I had to have a small script[1] run a quick check on every page you visit to check if the URL is a Pinpointer URL. As far as I can tell there's no way around this (and I'd say breaking backwards compatibility with HTTP is a bit drastic for a little browser extension like this).

Could you not use webNavigation[0] to check the url and permissions API to ask for permission[1] if necessary?

EDIT: Or tabs.onUpdated if webNavigation doesn't fire for hash changes[2]

There is the "activeTab" permission: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/ma...

It looks like that can only be triggered if the user interacts with the extension in some way. Presumably, then, it won't work if there's a script that should run on each page load.

EDIT: I had a look at the manifest.json[1], and it turns out that's the only permission I've requested. Not sure why Firefox says I'm asking for everything and the kitchen sink.
