browsers menu tooolbar

   Once upon a time, both Firefox and Seamonkey had a line/toolbar 
across the top.
   Unfortunately, i do not remember what it looked like to describe it.
   But i know the most recent version that will install in Win 7.1 
neither has that toolbar nor allows saving of passwords.

   It seems this new installation of Win 7.1 is already buggered enough 
to mess with the installation of Firefox, preventing decent and complete 
visual (and useful) results.
   Is there a way to fix the installation and know which older installation?
   I have (preferred) 52.9.0esr and 78.1.0esr, along with (tolerable) 
79.0b9, 80.0.1, and 86.0.1.

    Thanks.
