I recently got a new macbook pro (13 in. retina if that helps any) and have noticed that the bookmark icons for the browser are incredibly pixelated and look pretty bad. Even if the icon appears clear and sharp in the taskbar icon slot, when I drag it into the bookmark bar, the icon becomes really blurry. This has happened for every single icon except for youtube, which still remains sharp. I know this isn't a huge issue but it's been bugging me. Other browsers like chrome don't have this problem so it's lead me to believe that the problem has to do with firefox. Thanks in advance for any help that you can offer!
