Hi there.
Today I updated Firefox to the latest version: 43.0.3. Alas, Norton Toolbar & Norton Identity Safe were nowhere to be seen. I followed the directions to run LiveUpdate in Norton, close all programmes, restart my computer, load Firefox, go to the menu, thence to add-ons & click on Norton Toolbar to enable it if it was grayed (sic) out. I was informed that "Norton Identity Safe could not be verified for use in Firefox and has been disabled." As confirmation, beneath that I was informed (in brackets) that Norton Identity Safe was disabled. This latter piece of information was indeed greyed out but there was no response from anyone or anything when I clicked on the greyed out Norton Identity Safe.
Two questions: How do I get Norton Toolbar & Norton Identity Safe into Firefox? And the more general one of why instructions on the internet about solutions to computer problems so apparently inaccurate &/or incomplete?
