i want to look through ad pictures on ebay but firefox keeps stopping me opening new pictures for the same ad, if i open an ad initially it lets me view each picture then it starts blocking them, so that i can only view the main picture, its really annoying and i'll have to stop using firefox if it continues because it makes buying on ebay impossible and it's also doing similar things on other sites, i've reset the advanced tracking to standard and added an exemption for ebay but its still doing it ?????
