Since your latest UI update a few weeks ago your site seems to be leaking memory. A lot of it, especially on the "Margin trading" tab and a bit less so on the Stats page (in fact, almost every single page does so but these are the worst ones). That is to say if I keep the Margin tab open for a mere 24hrs it is consuming about 1.2+ GB of RAM, almost 15x as much as when it was freshly loaded. The Stats page within the same timespan is using about 4-5x as much as when it was freshly loaded.
I tested in the latest Chrome stable but I'm pretty sure it happens in any other browser.
My firefox has been quite RAM hungry lately and when I stopped using bitfinex in firefox, it's no longer eating up my RAM (the other browser doesn't get to show the leak because I changed my behaviour to "log in, trade, log out, close tab"). So I can confirm there must be some kind of leak somewhere.
Seems fixed since today or maybe yesterday. No more killing tabs daily. Thanks BFX.
