Gravity bridge problem on firefox

First, excuse me if this is not the right way to ask questions about the ATOM ecosystem.

ON FIREFOX the brige remains blocked when sending USDC by expemple from a metamask to gravity bridge (keplr wallet ok)
it seems to me that this is still the BETA version, so it may be useful that this bug is known. OR … I don’t know how to bridge an AH deal.
thank you for returning, it blocks me to feed and discover .
best regard

Maybe the best place to ask would be the Althea discord channel (dont have the link at hand, sorry)
