Hi,

this usually happens if Firefox is set to "Never remember history" or if it is in private browsing mode. In that case, the option to "Open previous windows and tabs" will be greyed out.

Please try this:

Go to Settings → Privacy & Security.

Under History, make sure "Firefox will" is set to Remember history (or "Use custom settings" with history enabled).

Restart Firefox and check if the option to restore previous sessions is now available.

If that doesn’t work, you can also check if any extensions or cleanup software are clearing your session data.

Hope this helps!
