Hello guys. I've been having this problem for a long time (like 2 years) but today I decided to ask for help since I couldn't find anything related to my specific problem on Google and now it really got on my nerves. I've also used the search function on this forum but to no avail. A picture is worth a thousand words so not to start typing a wall of text explaining everything in detail from click to click, I made a 3 minutes video that does all that. Please bear with it. http://www.youtube.com/watch?v=VgaCdvcNG_Q What's at fault here? I'm using XP Service pack 2 and Mozilla is at it's latest update. Thanks in advance. PS: It's not just for this gif in particular, it's the same for every gif that lasts for ~7+ seconds.
