"A script in the extension "Norton Identity Safe" is causing Firefox to slow down."

Have now disabled Norton Identity Safe, and anticipate that both Ancestry.com and LastPass will now work much better. The error message was incredibly frustrating, as it was difficult to get a screen shot.
Once I did, it was easy to remove from Norton.
Maybe Norton will give me a partial refund...

これを有効にするとブラウザがやたら重くなるので無効にしました
本当は星０にしたいくらいです

Firefox hat mich bei allen was ich im Internet gemacht habe begleitet, und gehört für mich mit zu den besten Browsern die ich benutze.
das heisst aber nicht das ich nicht auch andere Browser benutze, wie Chrome oder Opera jeder Browser hat in bestimmten Bereichen seine stärken oder schwächen.

I host my ecommerce wordpress woocommerce website at godaddy. Since the latest update, this extension completely interferes with the backend of woocommerce. It makes things incredibly slow and keeps flashing this maddening popup telling me there's a bad script, but before I can move my cursor to the disable option, the popup vanishes. As soon as i move away, it's back. And so forth, on and on. What crap.

Does not work well with firefox. If firefox updates, it takes Norton so long to update Identity safe that it only works for a little while before Firefox udates again and then the cycle repeats

been a user for years love it!

To buggy with having to try to get out of endless loop to correct the problem's.

Last version working relatively well was 5.1.1.2. Version 5.2.0.19 broke many sites including twitter and some forums I use. 5.2.1.2 still has this broken although not as bad as 5.2.0.19 (slows down rather then makes entry impossible). Up until recently you could backlevel to 5.1.1.2. Not sure if its no longer available because of some standard Firefox policy or because of Norton's pulling it.

Norton is getting worse and worse.
Its a shame, because the protection is good.
I'm starting to look elsewhere for my security needs.
Safe/vault will not work in Firefox or Chrome, only Explorer 11, which is ridiculous.
Its like Norton has decided that they only care about Norton.
Pop Ups??? They have to be kidding, of just plain stupid to think anyone would put up with that.
I need to get protection from THEM now !!
Chat is useless. Their instructions are incorrect. It seems like they don't know their way around their own applications.
And, as others have said, I will NOT give them control of my computer, as they ask for in chat.

Norton Identity Safe makes Firefox exceptionally slow. I received warnings from Firefox that Identity Safe was slowing it down.

It's crap and interferes with loading pages

I have used Norton's since the beginning of time including the Identity Safe. I am trying Foxfire again as a browser, surprisingly fast and lovely, also imported all my bookmarks nicely, but see we have issues with compatibility with age old Nortons. This is on Facebook, where there is a yellow flash incessantly and I have been able to click on each option it offers, with no results. In other words, the stop, wait, temporary disable buttons do not work. The learn more was not helpful. I would like to just turn off Foxfire notification for this item, if possible. I did see that in the add on list, you need to let each add on update! you would think that is a given ,but no, I changed all the Nortons add ons to that and then did a live update for Nortons, just in case there is some hold up in updating. Otherwise Nortons home page, safe web and identity safe are playing nice with Foxfire.

FIREFOX : rarely seems to work for any length of time on Firefox ...... (however, has yet to fail when installed on Chrome) ...... great idea but so far, my experience has been that it is far too unreliable to be of any use, if Firefox is your preferred browser choice .

Still doesn't integrate with Firefox. Today, a popup asked me to approve an update because Identity Safe needed my explicit permission to access six listed sites, none of which I have ever visited and none of which are listed in my Safe. There was no option to delete the sites, just an option to update with the relevant permission. This is either the start of a spam exercise or a programming error, neither of which is OK.
