Just a warning to those who have downloaded web utilities and have been running them on an offline computer. I was hoping that nothing ever gets stored on the computer, so that once I turn it off, there's no risk if the computer was stolen. Firefox was "storing sessions" or something like this.
Ugh. I should have known better. Haven't lost anything, but it sucks to know that your security wasn't nearly as good as you thought it was.
I really like all of the web-based utilities people have written in the Bitcoin community and would like to keep using them on an offline computer... if anyone has bullet-proof suggestions as to how to prevent the computer from storing anything (i.e., only keep things in RAM), please share! (maybe there is a stripped down browser I should use...?)
I know that using Armory would solve this and that many other offline transaction signing solutions exist.
