Yeah, that is the most worrying issue for Sri Lankan Firefox users. I switched from Google Chrome to Firefox because of its better privacy and lower RAM usage. However, Firefox doesn't support built-in Sinhala translations yet. Right now, I have to install external extensions just to translate a webpage into Sinhala, which is time-consuming and downgrades the overall user experience. Please add built-in Sinhala support to Firefox Translations, as @Roosweltjr suggested.
