Mh, well, no, you'd have to quit your browser if the LEAVE your accounting 
system, too. SQL ledger carries the password in the URLs it uses and there 
have been malicious JS scripts which managed to access the URLs stored in the 
browsers histroy list with some browser versions.
Even more easily the current URL containing the password could be 
accidentially passed to the site you visit after leaving the accounting 
system as the referer URL with a buggy browser.
Additionally there where some scripts which could read data from known files 
on disk so keep valuable data away from JS enabled browsers if you're really 
paranoid. ;)

However with a correct JS and browser implementation all this should be 
impossible. Browsers like Mozilla / Netscape 4/6/7 have been extensively 
audited AFAIK and are believed to be quite secure while IE is known to have a 
bunch of security bugs left. Browsers like Konqueror (which I'm using), 
Opera, iCab and Co. are not that commonly used and probably have not been 
examined that closely, so I would not trust their security too much. 
Konqueror just had a bug discovered in it's SSL-implementation. (The bug in 
Konqueror had been fixed within 3 days after beeing announced while IE which 
has the same bug still carries it... ;)  I trust it that much, however, that 
I use Konqueror for managing my private bank account.)
