I read in Mozilla's knowledge base to check the pref.js file to make sure it wasn't a read only file. I did that and it is not a read only file. In addition, I have pref files 1 through 88. i.e. prefs-1, prefs-2 ..........prefs-88. Is this suppose to be? The 88 files are dated 05/09/13 to 05/22/14. What else could be the problem that my preferences are not saved?

There shouldn't be any numbered prefs-##.js files or other files numbered in this way.

The presence of numbered files indicates that there was a problem with renaming the numbered temp file to the original prefs.js file, possibly caused by security software blocking this file.

Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.
