You can try this startup setting to make Session Restore work more reliably.
*Tools > Options > General > Startup: "When Firefox Starts": *"Show my windows and tabs from last time"
Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
Do a malware check with some malware scanning programs on the Windows computer.<br>
Please scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.
