Firefox freezes

[Maureen L Thomas]

Once again I am having problems with firefox.  Every time I do a search 
on anything the damn thing freezes and I have to shut it down by force.  
If I try to restore it without getting rid of all three tabs it locks 
again and again and again.  I have the latest upgrade from Debian for 
Firefox and am using Debian 9.  What can I do to fix this problem please?
