Scrolling jumps instantly to bottom of screen, will not scroll up

Just the other day my scrolling was working fine and now I'm losing my mind. I went on a mission to see if I could stop Firefox from automatically opening a browser window on computer start-up, didn't change a single setting while I did this, and now suddenly my scrolling is effed up.

I used to be able to cleanly and smoothly press the down key and flow all the way to the bottom, then press the up key and flow all the way back to the top. Now when I press the down key it either won't work or immediately jumps straight to the bottom, and when I press the up key it either doesn't work or it jumps straight back to the top and opens up random shortcut keys like Jump to Page.

In Options-Browsing I have autoscrolling and smooth scrolling enabled. I have tried disabling them, restarting, and re-enabling them, but the problem persists.

WTF is going on and how do I fix it?

You may have accidentally switched on caret browsing.

You can toggle caret browsing off/on by pressing F7 (Mac: fn + F7).

  • Options/Preferences -> General: Browsing
    remove checkmark: [ ] "Always use the cursor keys to navigate within pages"

Note that this is a Firefox accessibility feature.
