firefox hover preview over tabs not working

Firefox 147.0.2 (64-bit) on my Lenovo Yoga 7 Windows 11 Home has been randomly malfunctioning when i hover over tabs with the mouse to show what is in the tab. Sometimes it just fails for several hours, other times it works fine on its own later that same day.
I have tried to find this inside the browser several times with trying to find this browser tabs card Preview enabled But it doesn't seem to exist in this version and apparently you can't add a new rule inside the browser to solve it.

Google AI solutions search is outdated or the wrong version. My computer and browser are up to date.
How do i fix this ? I don't want to uninstall it, lose my logins and the bookmarks if i am unable to sync my files after trying to reinstall the browser only to find out it has failed.
