Zawgyi and unicode confilt
I want use firefox in android. But browser can't support zawgyi. So, it is more suitable if browser support both zawgyi and unicode fonts. Most of myanmar website still use the zawgyi. So, we can't use firefox in android. We used zawgyi about 20years. So, we can't easy change to unicode system.

Are you having problems with website content or the interface of Firefox for Android.
For website content we use the fonts that are installed on the phone. Can the stock browser or Chrome display zawgyi content? If the stock browser or Chrome can display the content then this is a bug we should be able to fix. If this is the case please let me know which model of phone you use and Android version.
For the interface that requires a dedicated set of people who wish to translate Firefox to the language. See https://wiki.mozilla.org/L10n:Localization_Process for details.
