Details

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170125094131

Steps to reproduce:

I updated to Firefox 51.0 today.   I then restarted Firefox.
I opened two tabs with known good websites.  Then I went to TOOLS and OPTIONS and under STARTUP I clicked on "Use Current Pages".   Both of the current pages showed up, separated by a pipe character.  Then I closed Firefox.


Actual results:

Restarted Firefox.  Both of the tabs I chose showed up as expected.
Then I restarted the computer.


Expected results:

When launching Firefox after a reboot, only the first tab shows up.  However, going to TOOLS and OPTIONS and under STARTUP, the correct two web pages are still there.   
And if I click on the HOME icon at the right of the screen, it WILL open both of the tabs.

Is it reproducible with your profile?

If yes, could you test with a fresh profile too?

Created a new profile and made it the current one.
Saved and closed Firefox.
rebooted computer.
Restarted Firefox.
First tab only opens.  
Closed Firefox
Reopened Firefox.
Both tabs open.   
During a session, opening and closing Firefox, the two tabs always show up EXCEPT when starting Firefox after a shut down or restart.

Is it a new behavior from FF51? Or did you observe it with older versions of Firefox?

I checked two other computers in our library yesterday.  Both had FF 50.  Both did the same thing.  
But 8 other computers with FF50 were working properly.  All of the computers are running Windows 7.
A real "head scratcher."
As I mentioned, the only time the second tab does not appear is after a reboot.  Otherwise, every time we open FF, it shows the two tabs just fine.

Does it happen if you close the Windows session (instead of rebooting which is "boring" for testing fastly) by changing the screen resolution (like 100 to 125%)?

01/31/17 I tried changing screen resolution.  That didn't have any affect.  Once logged on, after the first attempt to run Firefox, both tabs show.
When I logged off and back on and retried Firefox, only 1 tab was active.  BUT when I clicked on the HOME icon on the top right of the screen, BOTH tabs showed up.

I solved the puzzle!

Thanks to your hint about logging off and logging on, I noticed that Firefox was included in my STARTUP folder. And instead of a generic startup, it was set to open one specific page!  
I replaced that with the normal Firefox icon and, viola, it now works perfectly.

Thanks for your persistence helping me resolve this "bug" - another "user error"....
