plexiglass од Madalyn Parker

By installing plexiglass on a page, you can still see the page without being able to "touch" it with a mouse.

With mouse interactions turned off, you can challenge yourself to navigate pages using only the keyboard. With the screen overlay on, you will have to rely on a screen reader to use the page (NOTE: this works best on Windows).

This add-on is inspired by Marcy Sutton's no-mouse-days library.
