I can get back to using Firefox now.
Had to figure out to access vault via icon in top right. Actually like that the vault is a browser page. In Chrome the vault ribbon would lay over the top of the page I was viewing which was inconvenient.

This plugin slows down your browsing experience significantly. When visiting pages with many form fields (e.g. while working on my shop backend) the system almost freezes. I think it's because the plugins tries to establish a connection to the Norton server, which is incredibly slow.

Whatever you say in Symantec, this add on isn't functional...you should consider giving our money back because this problem exists 6 months already!!!

I prefer to use the local password vault option for NIS, yes you can still use the local option if you never set up a cloud vault. This addon does not see my NIS local vault and I refuse to use a cloud option. Are you freaking serious? The cloud is not safe and NOT PRIVATE!!!!!

FYI- Chrome and IE still work with the NIS password manager with a local vault. So you may be making a decision for me, unfortunately.

I loved using this add-on. It made life easier. What I despise about it is that every time Firefox updated, Norton's Identity Safe would no longer work for months...and months...and months. I had to use FireFox for school. I had tons of passwords I had to look up on the Norton Identity Safe website and write down individually. It sucked. I paid for all of the perks of Norton 365, not just the internet protection. It should work all the time or have a week of inconvenience at most. Norton has lost me as a customer.

Add-On told me to login. I logged in. Now it says 'Login in progress'. Tried it a couple of times, let it open for ~20 minutes, login still in progress.

Worth the wait of over a year.

This version works well now, after a bumpy start. Two inconveniences: (1) if FF is closed and reopened, the vault must also be reopened and (2) it is not possible to edit vault entries from inside FF. The latter problem can be addressed by opening the vault from inside the Norton product. Then entries can be edited through that vault access.

Windows 10, FF 48.0.2

Arbeitet mit der neuesten Firefox Version 48.0.2 ohne Probleme! Endlich.....

Man muss nur im "Add-on Store" unter Extras->Add-ons unten auf weitere Add-ons ansehen, klichen und dann Norton suchen. Dann das gewünschte Produkt installieren und den Anweisungen auf dem Bildschirm folgen.

Very simply

I says my vault is locked. When I press the OPEN VAULT tab, nothing happens. No pop-up or window change. Nothing to sign into.

I just tried again after the reply below. Still not working. I can't sign out of my account and I can't log into my vault.

Totally fails to function on my pc-latest up to date Win 10 Anniversary and FF48.0.2

This extension is not compatible with Comcast Norton Security Suite which uses a local vault.

I installed the extension, and after doing a FF refresh, the vault allows me to log in, when I go to a site, the login information pops up. I know this will get better as they (Norton) gets things working again

I see now its a prerelease. since being installed it gives the pop-up notice to sign in to use auto fill on the sites it recognizes I have stored passwords on. But if you sign in it doesn't load. Just says verifying Password like its loading but goes no further.
Hope this helps. Windows 8.1 Firefox 48.0

Doesn't work very well. The old Norton Toolbar works much better in Google Chrome
