I tried your fixes but when I open a new tab, FF still doesn't show me previously visited websites, just gray boxes that cannot be clicked. Any other fix ideas?
When I click a new tab, I can't get any of the 9 boxes to show my previous browsing history. I have tried changing browsing, privacy and history settings and nothing has worked. The boxes still stay gray, not clickable. Any suggestions?

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
To Reset Firefox do the following:
Go to Firefox > Help > Troubleshooting Information.
Click the "Reset Firefox" button.
Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
Firefox will open with all factory defaults applied.
Note that your System Details List shows that you have a user.js file in the profile folder to initialize some prefs on each start of Firefox.
The user.js file is only present if you or other software has created it, so normally it wouldn't be there.
You may want to check its content with a plain text editor if you didn't create this file yourself.
The user.js file is read each time you start Firefox and initializes preferences to the value specified in this file, so involved preferences can only be changed temporarily for the current session.
