If you are using firefox in Ubuntu Linux, you might have wondered how you can change mouse scroll speed.
To do that, you should roll up your sleeves and go to the hidden firefox settings.
In address bar type:
about:config
You will see a textbox and a long list of options and settings.
In the “filter” textbox type:
mousewheel.withnokey.sysnumlines
Change the default value to “false”.
Then type:
mousewheel.withnokey.numlines
The default value is “1”. Increase this number to have faster scroll speed in firefox. I personally prefer “6”.
You don’t even need to restart firefox to see the changes. They take effect on the fly.
