Hi all,
I created a Greasemonkey script to fix a number of issues and add a few nice features to Bitfinex.
Head here: https://community.bitfinex.com/showthread.php/277-Bitfinex-Greasemonkey-Cloudflareflare!-Fast-order-books!-Less-typing!-Less-calcs!

As of right now it has these features:
– instant page updates: the orderbook on the exchange/trade page will load as soon as the page does (instead of 30 seconds later) and update slightly faster
– USD value order editing: want to convert all the USD in a wallet into BTC without taking the calculator? Type your price and USD amount and the BTC amount will auto calculate
– Cloudflareflare Cloudflare mitigation: exasperated by your orders getting eaten by Cloudflare and being unable to trade for ~45 seconds every time? Here comes the rescue. Orders will submit in a hidden iframe. If the Cloudflare page is detected, the BUY and SELL buttons will flash "Cloudflared!" until the Cloudflare page clears. Then just resubmit when the buttons come back to normal. BONUS: submitting an order will not reload the entire page, losing the order book for 30 seconds!
– Confirmation for orders in transit: buy/sell button is replaced by a loading animation when the order is in transit.
– Click to copy price/volume: click on orderbook prices and volumes to autotype order. Want to snag that order at the bottom of the order book? Click on the price or volume and it will auto type it on the appropriate buy or sell side of the order form. REMEMBER TO ALWAYS LOOK AT THE ORDER YOU ARE SUBMITTING.
- Deposit interest information: yearly interest rate and interest per day data in deposit view.
