I don’t know why, but some people prefer to have a splash screen appear, as an application is loading. Netscape has one, the Mozilla application Suite has one, but Firefox does not.
Yes, you can add one, if you like.
– Download this splash.zip file.
– extract the files within it to your Firefox program directory
– edit the splash.ini file (text editor, like Notepad, should work), so the file paths are correct
– change your shortcuts to point to splash.exe
If you want to change the splash screen provided above, replace the splash.bmp file with a BMP file of your choice. Just make sure you rename it to splash.bmp, thus replacing the included file.
