Firefox for Android Community Forum

Hi there,

I am using Fennec from F-Droid (build 1340020). I noticed that many Brahmic scripts on webpages are shown as boxes. I don't recall seeing this in early versions maybe years ago.

Notably all major scripts in India like Devanagari, Tamil, Telugu can not be rendered. However, Odia and Sinhala scripts are shown fine. Outside India, Tibetan script cannot be rendered either. However, SEA scripts like Thai, Burmese are fine.

Moreover, if I copy these boxes to the search bar, the actual content can be shown. The tab view can also show the title of the webpage correctly in Bramic scripts. And if I change the locale in the settings, the UI of Fennec app can also properly display the scripts.

To further debug, I went to the about:config and search for fonts. Unlike western or CJK scripts, the value of font.default of Bramic scripts is serif rather than san-serif. The default value of font.name-list of these Bramic scripts are just Noto Sans or Noto Serif. I tried to switch between serif and san-serif but got no luck.

I was wondering how to fix this issue. Thanks!

I have just updated to Firefox v134 stable release on Android and now when I log into github.com, the webpage is glitching and not being rendered properly. The avatars on github look torn and they are blinking when I scroll up and down. This is occurring with current Firefox stable, beta, and nightly releases on Android.

My device is a Samsung T813 tablet running Android Nougat (Android 7.1).

I should also mention that Firefox v134 on Android is also showing UI glitches when viewing the settings in certain extensions, like FoxyProxy. Although, I have also done a clean install of Firefox v134 with no extensions installed and the webpages like github and still showing the rendering problems mentioned above.
