I've grown tired of Norton's indifference toward us FF users using ID Safe, so I finally gave up. If any of you are like me, I found the switch to LastPass much easier than expected (export IDSafe, import to LastPass), and after a month, I've found that I now much prefer it to IDSafe and I can use my preferred browser, Firefox.
If you are interested in LastPass, use this link: https://lastpass.com/f?18080322 (disclaimer: I'll get a free month of premium subscription for every two folks that register if you use that link, if you prefer not, just drop the /?18080322)
