[Suggestion] restrict authorisation to access website data

When installed on firefox from addons.mozilla.org, the extension requests access to data from all websites.
Why not keep a list of known moodles servers on the github and update it gradually, so that you only request access to these sites?
We could possibly keep "access to all websites" as an optional authorisation, in case a user wishes to use the extension for a site not listed.

Hello,
Thank you for pointing it out. You are right, the extension shouldn't ask permission for all websites.
I will open a pull request to fix this!
