When viewing Kannada text in Firefox 142.0.1 (64-bit) on macOS [your version], conjunct letters (ottaksharas/ligatures) do not display correctly. Instead of showing combined forms like ಶ್ರೀ (shri), ತ್ವ (tva), ತ್ರ (tra), the characters appear split into individual glyphs. This issue is browser-specific: In Safari and Chrome, the same text renders properly with correct Kannada shaping. In Firefox, the ligatures fail to render, making Kannada text appear broken and unreadable. Apple Support confirmed that the system rendering is fine and advised reporting this to Firefox. Example text (should be tested): ಚೊಕ್ಕಾಡಿ ಶ್ರೀರಾಮ ದೇವಾಲಯದ ವಾರ್ಷಿಕೋತ್ಸವ
