Cannot open app on firefox(exception thrown: 15354424) but work with Chrome

tham

OS : win 10 64bits
Firefox : 69.0.3(64bits)
Error message : Application exit (15354424)
Qt: 5.13.1
emscripten : 1.38.27

Works for Chrome : 77.0.3865.120 (Official Build) (64-bit)

Do anyone know what do 15354424 mean? I open the console but it only give me "exception thrown: 15354424"

Tried with Qt5.14.0 beta 1, the error message change to

"Link Error: Import object field 'Hm' is not a Function"

Chrome still work, but this time it cannot show unicode characters on QTableWidget, while Qt5.13.1 can

Using emscripten : 1.38.27

Edit : Qt5.14.0 beta 1, every widgets need to load the fonts manually

Firefox 70.0 works again.
