Permissions:

Does not require any permissions upon installation.

In Options, if you decide to try the highly customizable expert button modes – modes that work by adding the button(s) onto all pages unless you choose to disable it for certain pages or websites – the following permissions will be requested:

“Access your data for all websites” is used to add the button(s) itself, its logic, and its design properties onto all websites without extra actions from you.

“Access browser tabs” is used to check the URL of a tab:
1) There are some default websites where the button doesn't get added because it wouldn't work there (for example, Google Docs and Google Sheets).
2) You have the ability to disable the button(s) on any website (example.org) or URL (example.org/blog?page=1) by clicking the extension icon next to the address bar and selecting the appropriate option.
