If you are using Firefox / Librewolf on Linux / Unix and wonder that your mouse cursor won't turn into a hand anymore when hovering over links, you may want to try setting (in `about:config`) `widget.gtk.legacy-cursors.enabled` to `true`. After a restart of the browser, the hand cursor should be back.
