I'm very happy with this extension:

I get frustrated by having to retype routing/account numbers, or not being able to paste them in the first place. And the ubiquitous e-mail address confirmations. (Given that I still get dozens of e-mails sent to me intended for other people, not spam, just sent to the wrong address, this isn't working. People mistype their e-mail addresses multiple times. You really need to verify the e-mail address by sending an e-mail and asking for a code or a click.)
