Okay so I have only been recently noticing this problem within the last couple days and although it does not interfere with how websites work it is getting a little bit annoying... I have noticed this problem mostly on Facebook and Youtube. Basically what happens is some images will be in the place of other images until I hover my mouse pointer over them then they will disappear to reveal the correct image. A youtube example would be: When you first go to youtube and sections of recommended videos, watch it again, and other categories of frequently watched channels show up with several videos... well lets say for example that the first line of 4 videos in order from left to right read: red yellow blue green and their picture is of an apple, banana, blueberry, and a green grape... Well in this instance the green grape would load fine, blueberry would load fine, but then apple and banana would be replaced by blueberry until i would hover my mouse pointer over it and then the correct pictures would show up. Here is a facebook example: When you are "home" on your wall and you can see your user picture upper left corner and you scroll down to read some stories, or you go to the site on the next tab over, you return to find the first person on the wall who is posting's user picture over your own until you hover over it and then it shows your correct one...this will also happen with the my pages icon on the right side and sometimes the my pages icon will be correct but my upper right arrow on the scroll bar will have my business page user icon from my pages instead of an up facing arrow, again, until I hover over it to clear it. I have googled this problem and have found some forums that say clearing the cache helps and it didn't if anything it seemed to have made it worse...I have also done a virus scan and I do not have any infections etc... Can someone please shed some light on this small cosmetic yet irritating problem?? I really appreciate any information anyone can give me...like if this is even a firefox thing or if it is my computer or what. Thanks!
