B4J Question [ABMaterial] different make-up website in firefox

Firefox on pi is probably not a full blown version?

sorry, i'm using same firefox, app is running on a non UI rasp

firefox (on pc)--> running app on pc : ok
firefox (on pc) --> running app on Pi: different make-up
chrome(on pc) app running pc or Pi, ok
IE (on pc) app running pc or pi: ok

ok, I read that wrong

It should be the same. Try pressing F12, console and check if there is some error (or compare the pc/pi versions). Also try pressing CTRL+F5 to reload all CSS files. If you can take a screenshot to show the difference I may be able to tell more.

I'm running almost all my ABM apps on a pi and never had a different make-up so something must be missing.

bingo.... F5... reload the CSS
your're great Alain
