  • Que cada dos por tres quiere que utilices otras aplicaciones de norton, como buscador predeterminado, guardar contraseñas.....
  • the best i have found and used in a while quick, easy, secure all at a click and a glance.
  • Privacy policy summary: "We metaphorically have someone sitting besides you with an unblinking eye, watching and recording every keystroke you type and every website you visit and save this information for profit"

    It's sad users are subjected to legalese and spyware has become the accepted norm among 'free and proprietary' services. If this were some random add-on developed by some nobody it would have been appropriately removed from mozilla services.

    Protip: Firefox already has Google Safebrowsing for malware. All you really need is to block ads and malware domains with Ublock add-on and scan files with the virustotal website. If you still need this add-on, maybe you should reconsider your browsing habits.
  • Works great as a Norton extention
  • havent really used it much but I love Norton products.
  • Facilité d'accès
  • I have used Norton/Symantec products for years and am very pleased with them. I have never had to deal with a virus infection in all of those years.
  • I feel safer with the Norton safe search
  • Super fajny dodatek. Polecam
  • incompatible with the google search engine, guys need to fix this.
  • interessante ma a volte non trova quello che cerchi
    da migliorare
  • Great add-on for security, but still inferior to the legacy version at some fields:
    – Blocks malicious websites a bit late (I believe that it’s a restriction of the WebExtension technology), and every time during a browsing session, i.e. even if I just accepted the danger and click on an internal link on the page (this can be fixed).
    – Still not marking safe and malicious websites in Google search results, but asks me time to time to set Norton Safe Search as the default search engine. I don’t want to use that awful piece of software, I want to use Google or Bing or whatever I’m used to, with the little badges by the Norton extension. It’s not that hard to achieve even with WebExtensions.
    – I don’t remember how it worked before, but when the extension thinks that a download is malicious, I can’t download it. If I know that the extension is wrong, I have to disable it to get the file downloaded.
  • It worked!!!
  • computer freezes all the time since I added this
  • I just compared this Norton addon with the Bitdefender Trafficlight addon on the AMTSO test site and Norton was much more effective, it basically blocked everything, unlike Bitdefender Trafficlight. This Norton addon is an important extra layer of defence agains malware and viruses when you browse the web.
  • Unfortunately it now confuses both computer and cellphone ... It didn't before the phone entered the picture!
  • Have used for years and have been happy with service
  • Was running perfectly but suddenly over the last few weeks a yellow bar flashes up for a split second. I have finally been able to grab a screen shot to see what it says and its this Norton Extension. It was fine but now its not. Other reviews point towards some update in December as being the fault. no good Norton!
  • Super handy! I'm always wary of the websites I visit, and love any tool that helps keep me safe.
