Found a Great New Way to set Startup Pages
You need to have your history on for this to work.
Pin the Tabs you want to have startup with the Browser. EG Email, Chat, Rainbo.io, etc
When finishing your session leave these PINNED Tabs Open and Select the X in the upper right hand corner.
Start Firefox as you normally would and you will see that any PINNED Tab will automatically reopen in a new Firefox Session.
This avoids setting multiple pages as I have found you can cause your startup pages to reappear again when you are using Firefox. Works Slick and is much Cleaner.
Enjoy!!

Plus by keeping your startup items PINNED they save Space for other TABS in Firefox.
Note that pinned tabs are specific for a window and best in such a case is to Quit/Exit Firefox using the File menu or the "3-bar" Firefox menu button drop-down list instead of clicking the X what can cause you to lose the pinned tabs if there are other windows still open as only the last closed window is reopened.
