[TriLUG] Big Problem with Firefox after Upgrade to Ubuntu 22.04

[Scott Chilcote via TriLUG]

   Hi TriLUGgers,

   This is probably a snap related problem, but my just-upgraded Ubuntu
   system has a completely empty configuration when I start firefox on my
   existing account.  I have not had to use Firefox as a snap on this
   system before.  The previous 20.04 install used Firefox as a debian
   binary package.  Unfortunately, 22.04 will only install Firefox as a
   snap.  It says this in a notification window during the upgrade
   process.

   I still have the old firefox configuration (bookmarks, logins,
   extensions, etc.) in my $HOME/.ubuntu directory path, but this is being
   ignored.

   The bookmarks import wizard displays a window that says that there is
   no browser install that it can import on the system.

   It does not appear to be an access permissions problem,
   /usr/bin/firefox is owned by root/root and my .mozilla path and files
   belong to my personal user and group.  But I don't know how relevant
   that is to a snap.  Perhaps it can't reach outside of its own sandbox?

   Does anyone know what I need to do to get the firefox snap to use my
   existing $HOME/.mozilla configuration files?  Do they need to be
   relocated?

   I can't imagine why the snap install didn't take care of this, but
   perhaps there was a problem that kept it from working.  I spent half an
   hour searching for how to correct this problem, but it must be rather
   unique.  I found a total of zero matching problem reports.  Perhaps I
   just didn't use the right descriptive terms...

   Thanks muchly for any clues!
