Firefox complaint

[Maureen L Thomas]

I have used firefox for ages without a problem til now.  I am using the 
latest update of debian 12, on a HP computer that is using linux quite 
nicely.  Any way all of a sudden there are web pages that no longer open 
on firefox.  Credit Karma, our local Bob Evans rest., and a couple of 
others.  Is there a problem with firefox-esr 115.15.0esr-1~deb12u1.
