Firefox: slow scroll

I recently updated Firefox to a newer version.  I found that when using the up/down arrows on the side scroll, the scrolling is really slow compared to previous versions.  Is there a configuration item that can adjust the speed?  My searches have brought up ways to change the "mousewheel" scrolling, but that is not what I am looking for.  Thanks.

You may have too many extensions installed which could be the issue.  Use Safe/Mode/Troubleshooting Mode URL from Post # 2  as it will start FF with no extensions so that will determine if they maybe the issue.

Can look at things but there are Extensions : https://addons.mozilla.org/en-CA/firefox/search/?q=Smooth%20Scrolling  Try : yet another smooth scrolling Extension.

Can also go into Advanced area by typing or copy/paste about:config into the Address Bar (Wonder Bar) and accept the risk.

Copy/paste : toolkit.scrollbox.verticalScrollDistance and can change the numerical number up or down. NOTE: Make sure you keep track of what you do to reverse it if need be.  NOTE: need to restart Firefox for changes to take effect.

Can also try in about:config  - general.smoothScroll.lines.durationMaxMS  and general.smoothScroll.lines.durationMinMS  can go to 0 if need to.  Suggest start there.  Remember save info for what you change to set it back.

All changes take effect on Firefox Restart.

Can run from Start Menu : Disk CleanUp then run it again and Click the box : Clean System Files.

As well just to make sure run : https://www.bleepingcomputer.com/download/adwcleaner/  Do not skip the last step.

Note : if it finds anything keep the log.

As to User Profiles, Adware, and Disk Cleanup, this is both a fresh install of Windows and a new install of Firefox.  Further, if I uninstall FF and re-install the old version, it works fine.

toolkit.scrollbox.verticalScrollDistance --I found that this setting changes how far the page moves on one click of an up/down arrow.

general.smoothScroll.lines.durationMaxMS -- this is the one.  This does what I needed.  (!!)

general.smoothScroll.lines.durationMinMS--I didn't need to try this one.

Thanks!

Glad that worked out for you.

Always keep a notepad of changes made so in case another version may need to change that again or change back.

Thanks for letting us know
