Dear Firefox Team, It has re-occurred to my Firefox Browser of the latest version of 115.30 with some websites which I have recently visited however which have appeared 8 grids of blank or white pages again under "Recent Activity" as attached with the image for your technical troubleshooting suggestion. Those 8 grids of Recent Activity in the older version of Firefox browsers used to have shown colorful graphics or images representative of the recent websites I visited in the recent past. May I know what I am supposed to do to recover those graphics or images? Kindly offer any suggestion or solution? Thank you for your kind attention.
