9 about:config Hack to Make Mozilla Firefox Faster

Updated: March 9, 2018 / Home » Desktop Computer Software » Internet Web Browser

Some say Mozilla Firefox is better, while others say Google Chrome is. Whatever it is, the best browser is the one you find the most user friendly, for that reason I prefer Firefox over Chrome and Internet Explorer. Speed is not an issue, it doesn’t make any difference if the site is 1 second faster over another. However, if you are using a very slow computer, especially those in your work office where you have no say in the hardware, you might find these simple hacks useful.

      kris, you make them if they are not there
      if its true or false you right click & make a new Boolean entry—if its a number like 10 you right click & make an integer entry, you can right click in or near the “value” heading

    These are old tweaks and some have been made obsolete. You really need to do your home work before copying old articles
