If it's annoying then we should already see some complaints or suggestions about it. It means everyone is used to it and no problem at all.
What are those several sites according to you that are not resetting the settings even after a refresh?
i did not listed the sites, cause it would feel odd in a "yolo"dice thread to list the competition(s), if i get clearance i can i will do, otherwise if you really wanna know i can pm you the sites (without my refs)
