I have the same problem with Firefox 7.01 and Lion OSX 7.2. I followed the procedure shown here http://digitaltibetan.org/index.php/How_to_configure_Web_browsers_for_correct_display_of_Tibetan_script However, though I restarted firefox and the MacBookPro the Tibetan script doesn't show up. '''There is no such problem in Safari!''' The Tibetan scripts are activated at my Mac OSX Lion platform, I added even Tibetan as a preferred Firefox browser language. '''---I made a check with older Firefox versions---''' I downgraded Firefox to Firefox 6.02 and Firefox 4.01. The latter shows the Tibetan script in Firefox correctly, so there is a problem with versions higher than 4.01 at the side of Firefox! As soon as Firefox >= 6 is used the Tibetan script disappears. Therefore I assume '''this is a bug in Firefox.''' One can check the functioning/non-functioning here: http://en.wikipedia.org/wiki/Tibetan_script Also Firefox 8 does not support Tibetan script. Note that all the tested Firefox versions used ''the same setting''. I attach a screenshot of Firefox 4.01 and Firefox 7.01. '''Amendment:''' Since I use Mac OSX and this question here is related to Win XP, I posted the problem also here https://support.mozilla.com/de/questions/888694
