Please accept the idea to supporting safe browsing using Dolphin Browser.
Among 3rd party browsers, I guess most people are using Dolphin. And some free antivirus apps are supporting Dolphin, it is a disadvantage that Norton dose not.
Hi darrenl
I am sure there would be a lot of Android users of Norton Mobile Security ( NMS ) who
would like to see the Web Protection of NMS work with the Dolphin Browser.
There is a Norton Community Forum that is for Product Suggestions where perhaps you
could post the idea for the Norton Mobile Team, you can use the link below to find the forum.

Also i believe a new browser was just added to the list of browsers that NMS Web Protection
is compatible with, being Chrome and Chrome Beta along with the Android Browser and just
new in the release notes for NMS version 3.8 in the forum is the compatibility with the Samsung
Browser now.
More about the release notes from Norton Employee Gayathri_R can be found using the link below -
Thank you for your feedback on the NMS product and i hope you find my info to be helpfull. :)
Cheers. 
Hi smithy,
Thanks for your reply.
I read from the in-app help page that NMS 3.8 has added support to stock Samsung browser, with Chrome and Chrome Beta already.
But sometimes the above 3 browser do not work smoothly.
But it is a good news that Norton is evaluting Dolphin Broswer. Hope not wait too long to support it.
Best regards,
Darren
