when i start the newly installed firefox in my ubuntu the tab crashes. only settings and other in app menus could be opened. Nothing can be shown inside tabs. Only showing "Gah! Tab crashed!" . I don't think I'm missing any libraries. Glibc is 2.31, libstdc++ also is updated and same for gtk and all. Below is the error message:- '''bold text''' already installed. still same error :- (/usr/lib/firefox/firefox:25764): Pango-WARNING **: 14:06:40.948: font_face status is: file not found (/usr/lib/firefox/firefox:25764): Pango-WARNING **: 14:06:40.948: scaled_font status is: file not foun Crash Annotation GraphicsCriticalError: |[C0][GFX1]: no fonts - init: 1 fonts: 7 loader: 0 (t=30.4485) [GFX1]: no fonts - init: 1 fonts: 7 loader: 0
