Cannot change mousewheel scroll value

After re-installing windows and everything that I had on my old desktop, I seem to be unable to change my mouse-scrolling amount on firefox. I've looked through all the troubleshooting questions that have already been posted, and all the users answered that I had to access about:config and change the mousewheel.withnokey.numlines value.

However, when accessing about:config, I've discovered that not only do I not have the specified integer I have no integer with a preference name that contains "withnokey" , so I had tried to add it in myself, but to no avail. Currently my scroll is doing about 6-7 lines, and I'd like to lower it down to about 3.

hello Skarlath, the scrolling behaviour was overhauled in firefox 17 (for technical reference see https://wiki.mozilla.org/Gecko:Mouse_Wheel_Scrolling) - the old setting won't have an impact any longer.

it should still be possible to set a different scroll speed. you can enter about:config into the firefox location bar (confirm the info message in case it shows up), search for the preferences starting with mousewheel.default.delta_multiplier_ ... you can double-click those settings & assign a different value to them - then a restart of firefox is required for changed settings to take effect.

Thanks! The article you linked essentially solved the problem, as while changing the mousewheel.default.delta_multiplier_... value did slow down everything, I couldn't specify any value.

For anyone else who has the same problem as I did (as if haha), search for the mousewheel.system_scroll_override_on_root_content.vertical.factor option, and then change that number to your preference.

Once again, thanks philipp!
