When installing Serbian Firefox 3 on Windows XP system that has a non-Cyrillic system code page, the installer text shows as gibberish. More precisely, shows the glyphs from a latin code page, making the text unreadable until the user switches to a Cyrillic code page. A consequence, an user cannot install Serbian Firefox 3 on such a system without first changing the system code page. IMHO we should not make the user jump through such hoops to install the program. See Bug 424091 for sample screenshots.
