After an auto-upgrade Firefox quantum to 66.0, scrolling sites with arrows keys (up / down) not working properly, scroll jumps to a paragraph of the webpage and select texts box and so on. I can't scroll smoothly.
How do I fix that?

OS: Xubuntu 16.04.6


You can enable/disable smooth scrolling & go back to the old behavior in Preferences > Type "scrolling" in "find in preferences" box. There you may find the desired Scrolling options.

    If just toggling an option in Preferences solves the problem, then it's most likely not a bug. – pomsky Mar 22 at 17:06
