To speed up mouse scrolling speed in Firefox in Linux Mint. This also works in Pale Moon browser. Also makes scrolling smoother and less jumpy. (This also works in other Ubuntu based distros.) In the Firefox URL field type, about:config and press Enter. In the Search field type, mouse Double-click on... mousewheel_system_scroll_override_on_root_content.enabled, default, boolean, false to toggle it to true. The line will now be displayed as: mousewheel_system_scroll_override_on_root_content.enabled, user set , boolean, true Click on the Firefox top menu Edit, Preferences, Click on Advanced, General Make sure [X] Use Smooth Scrolling is checked. This speeds up my mouse scrolling considerably in Firefox.
I didn't like the Firefox Search Bar. I rarely used it. It takes up valuable real estate that can be used by other ADD-ONS Icons. I Just do my searches directly in Google or Bing. To remove the Firefox Search Bar (this actually just moves it and stores it away, you can bring it back), -Click on the upper right menu icon (three lines). -Click CUSTOMIZE -Left Click, Hold and Drag the Firefox Search Bar down to the Additional Tools and Features area. It will be saved there in case you want to bring it back. -Click EXIT CUSTOMIZE. The Firefox Search Bar is now gone and the space can be used to add additional ADD-ONS Icons. If you want the Firefox Search Bar back, just drag it back to the original place after clicking CUSTOMIZE.
