[Ham-Computers] Mozilla Firefox Questions

[Robert Downs via Ham-Computers]

Doesn anyone know the name and location of the Bookmarks (Favorites) file 
in Firefox?

Does anyone know how to "back up" from version 29 to version 28?  After I 
installed 29 on Saturday, I discovered that I can no longer print anything 
usable from web sites like eBay or Vendio with our big Xerox 
printer/scanner/copier because something is overriding the default paper type (Letter) with 
Tabloid.  And automatically formatting whatever you want to print as Tabloid. 
 So if you try to print anything on letter (by changing the default at 
print time), it chops off top, bottom, left and right.  The only printer that 
still works is a Xerox 3300 which does not know what Tabloid is.  And yes, 
anything printed through any program other than than Firefox 29.0.1 (like 
Stamps.com, Word, etc.) or through IE8 still works fine.  So it is definitely 
Firefox.
