Can one print out a character sheet on Mozilla, the standard of browsers?
Have there been a way to test this out without paying for it initially? (I have still not been able to log in using my HLC license)
Firefox is definitely not the standard. Its a preference to some but definitely not most.
Also you don't log into HLO with your license. This has been stated several times. You need an account. Create one or if you have Realm Works you use that account.
