I let 4,000 submissions build up in my FA message center.
FA has grown so borked, slow, and JavaScript-heavy that, well... I tried going through them Saturday with JavaScript from only www.furaffinity.net allowed and barely managed 200 because of how slow each page was to load. I disabled JavaScript on all of FA Sunday, and the speed improved to where I cleared out 3,500.
Tangentially related, the biggest reason I still use Firefox is because of NoScript. I haven't found any block-by-default selective JavaScript blockers for any other browsers.
