I have custom start pages in my settings but most of the time when I start Firefox, I get the error message Sorry. We’re having trouble getting your pages back. We are having trouble restoring your last browsing session. Select Restore Session to try again. Still not able to restore your session? Sometimes a tab is causing the issue. View previous tabs, remove the checkmark from the tabs you don’t need to recover, and then restore. Why is this happening and can it be fixed? If I click on start new session, it opens my custom state pages.
