information about plugins in TB is not complete
The source text link: https://tb-manual.torproject.org/plugins/
The paragraph:
Tor Browser includes an add-on called NoScript. It's accessible through "Preferences" (or "Options" on Windows) on the hamburger menu (≡), then select 'Customize' and drag the "S" icon to the top-right of the window. NoScript allows you to control the JavaScript (and other scripts) that runs on individual web pages, or block it entirely.
This menu is now accessible through the hamburger menu (≡) - "Add-ons and themes". And overall slightly different from what is described in the Manual.
