1. How to disable automatic plug-in installation

If you visit a page which requires a plug-in you do not have, Mozilla and Mozilla Firefox will pop-up an annoying box asking you to download and install it.

This is, for most people OK. But what if you do not want to install any more plug-ins?

Mozilla and Mozilla Firefox does not have an option for this, but there is a trick:

Remove the file libnullplugin.so from your plug-in folder! This makes your browser STFU about missing plug-ins.

Your plug-in folder is probably one of the following:

Mozilla:

  /usr/lib/mozilla/plugins/
  /usr/local/lib/mozilla/plugins/

Mozilla Firefox:

  /usr/lib/MozillaFirefox/plugins/
  /usr/local/lib/MozillaFirefox/plugins/

2. How to edit preferences not available through the configuration dialog

In Mozilla 1.x and Mozilla Firefox you can change all settings by typing in

about:config

in the url address bar. Here you can change things not available in the normal config dialog.

You can also find out what version you are using by entering the address about:, and find out what plug-ins you have installed at about:plugins.

2.1. How to make the fonts look better

If Mozilla 1.x or Mozilla Firefox is compiled with --enable-xft (this is true on most distributions) then you can make the fonts look better by setting some hidden configuration options.

Enter about:config in the location address bar.

You will now get a list of all available options, even those not visible in the configuration dialog. Look for

  font.Freetype2.autohinted
  font.Freetype2.enable

And set them both to true.

For more information:

Bitstream Vera fonts look good and are suitable as default fonts.

3. How to make Mozilla identify as Internet Explorer

Go to about:config and change:

   general.useragent.vendor
   general.useragent.vendorSub
