stuff.mit.edu - Missing host permission for the tab

[ianchanning]

• Browser: Firefox v109.0
• OS: Pop_OS! 22.04 LTS
• Extension version: 0.6.9

For some reason on https://stuff.mit.edu I get:

"Missing host permission for the tab"

and it refuses to display your reader view. I tested on various pages all the way up to the root. This was the first page I came across: https://stuff.mit.edu/people/dpolicar/writing/poetry/poems/fareForward.html

Seems that it's a general Firefox extension problem, but not sure why I get the error just for this one site and not others. For example https://mit.edu is fine.

From what little I know its something to do with the manifest.json permissions and host_permissions.

Further notes - the page is in 'Quirks mode'

Regular Firefox reader view works:

The similar plugin to yours, unclutter, also fails, but fails silently.

The site is sandboxed, hence the extension is not able to access its content! As far as I can tell, there is no way to bypass it. I'll keep this open for suggestions.
