Signing in with Firefox, I get javacript/cookies error, javacript is on, cookies are on, ad block is off, I signed on with EDGE instead

Why do I keep getting javascript errors that say enable javascript, enable cookies, disable ad block, when javascript is already enabled, cookies are already enabled and ad block is off?  I did the PRESS and HOLD thing, it went across, showed 3 dots, and just sat there.  Tried multiple times.
