Reply #23: User.js [View All]

That is an excellent tweak for many systems, but be aware that the speed increase is an illusion. All that does is tell Firefox to start drawing the page before it has all the data it needs to draw it correctly. This can result in some pages appearing rather odd looking at first.

FWIW, all these tweaks are more easily accomplished via a user.js file, easier in the sense that if you want to change them, add to or delete them, you just have to change a line in the file.

The user.js file is a standard text file that can be created using any text editor, like Notepad. It should be placed in your default profile directory.
