Failed to copy text: Error: Missing host permission for the tab

Flatpak版Firefox 110.0.1において、下記、URLでエラーが出るようです。
https://addons.mozilla.org/ja/firefox/addon/format-link3/

Failed to copy text: Error: Missing host permission for the tab

I don't think accessing URL of subdomain addons.mozilla.org from extensions is allowed in Firefox. I'm running 111.0b8 (64-bit) in Windows 10 and the extension shows a blank content for the above URL, which is the expected behavior.

With url2clipboard, it seems possible.

Interesting, the extension you provided does work in this situation, which is new to me.
