Here is instruction about installation Myanmar Language Pack.

# The translation package requires Mozilla Firefox 3.6.x, therefore make sure you have the latest version from http://www.mozilla.com/
# In Firefox 3.6, click on http://www.wordpress-my.tk/langpack-firefox-3.6-my.xpi You will be asked whether to Allow to access the extension;

1. Click Allow to accept.
2. Click OK to install.

# Now we need to install an add-on that allows to switch to the new Burmese translation.

* Click on Tools→Add-ons→Get Addons and
* search for “locale switcher”.
* You will get two results; 'Quick Locale Switcher' and 'Locale Switcher'. Both work, but it is much easier to use the 'Locale Switcher'.
o Select to install the Locale Switcher.Quick Locale Switcher does not detect that the Burmese langpack has been installed. Go into the preferences and in one of the three Custom fields add 'my' and 'Burmese'.

# Restart Firefox.
# Go to Tools/Languages and select Burmese. You will be asked to restart Firefox. Restart Firefox and you get Burmese localisation!
