AutoScroll Pro by Ruban S

AutoScroll Pro scrolls the page for you, at a pace you set, so you can read
long articles, comics and documents without touching the wheel.

WORKS WHERE OTHER AUTO-SCROLLERS STALL

Most auto-scroll extensions assume the browser window is what scrolls. Very
often it isn't. Blogs put the text in an <article> element, manga readers use
a reader panel, and web apps scroll inside a fixed layout. AutoScroll Pro
checks what actually has room to scroll and targets that instead of guessing.

It also handles the things that fight an auto-scroller:
• Pages with CSS smooth scrolling, which make other extensions stutter or crawl
• Snap-scrolling pages that drag every step back
• PDF auto-scroll works in Firefox's built-in viewer.
• Infinite-scroll and lazy-loading pages, where it waits for new content
instead of stopping at a false bottom
• Works on Firefox for Android. Turn on the floating controls in the options page, since Android supports neither keyboard shortcuts nor right-click menus.

If it still picks the wrong area, use "Pick scroll area" and choose it
yourself. Your choice is remembered for that site.

CONTROLS

a different speed to each
• Auto-advance to the next chapter when you reach the end
• Loop back to the top instead of stopping
• Focus mode dims everything outside a reading strip
• Timer mode stops after a set duration
• Remembers where you stopped, per page
• Remembers the speed you chose, per site
• Saved profiles for sites you read often

PRIVACY

AutoScroll Pro requests two permissions: storage, to save your settings, and
contextMenus, for the right-click menu. It requests no host permissions at
all. It makes no network requests, collects nothing, and tracks nothing. Your
settings sync through your own browser account and go nowhere else.

KNOWN LIMITATIONS
• Content inside a cross-origin iframe will not scroll.
