Browser UX Scrollbar Visibility by Samuel Lair

Keep vertical scroll controls visible and usable on websites that hide them. Browser UX Scrollbar Visibility restores page and nested-container scrollbars and provides local scroll rails for supported dialogs and popovers.

It works automatically on supported HTTP and HTTPS pages and eligible frames. Browser-restricted pages and some native or site-specific controls are outside its scope. You can disable or remove it through Firefox.

No accounts, analytics, telemetry or external data transmission. Page layout and interaction information are processed locally only to provide the scrollbar feature.
