Firefox after version 39 does not restore tabs from previous session relyable.
Up to version 39 all tabs (I have some 500 open...) had been restored correctly on start of firefox. Since version 40 they are restored one or two times and then forgotten. I have tried version 42 but I go back to 39 every time since the bug is not fixed since 40. Version 39 works 100% relyable.

Are all tabs missing or do the tabs open but with the about:blank page (no URL)?
Did you look for History > Recently Closed Tabs/Windows?
Did you verify that Firefox closes properly?
Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
- "3-bar" menu button > Exit (Power button)
- Linux: File > Quit
- Mac: Firefox > Quit Firefox
- Windows: File > Exit
