User.js
User.js allows advanced customization of Mozilla Firebird.
Open up explorer to the profile folder (In WindowsXP the folder is usually located at %AppData%\Phoenix\Profiles\default\xxxxxxxx.slt\) To enable some of the experimental features described in this guide, creating a blank txt file named user.js in that folder.
** Enable Pipelining
Pipelining is an experimental feature that speeds up how fast the browser loads a page. Some sites (like Google's Image Search) slow down when pipelining is enabled.
Add this code to the user.js file created above:
// Enable pipelining:
user_pref("network.http.pipelining", true);
user_pref("network.http.proxy.pipelining", true);
user_pref("network.http.pipelining.maxrequests", 100);
** Add a Registry Entry for Mozilla Firebird
When you add a registry entry for Mozilla Firebird, it allows easier installation of the Flash, Shockwave and RealOne plugins because it allows these programs to detect that Mozilla Firebird is installed on your system. If you have Mozilla Firebird installed somewhere else than C:\Program Files\MozillaFirebird, edit the .reg file to the correct path.
Download
this registry file and open it.
** Enabling Fast Rendering
Gecko normally delays rendering by 1200ms to lower the amount of reflows (more reflows equals a longer total page load). If you wish to have a faster first load and don't care about the longer total page load using this hack can be very beneficial. When you enable fast rendering you are bringing down the delay to 0ms.
Add this code to the user.js file created on the first step:
user_pref("nglayout.initialpaint.delay", 0);
