Firefox 39.0 crash while searching with Google or Bing. Not every time, but at least one or two times a day, FF crashes when I move the mouse over a Norton url-safety-status icon, which are shown for each search result. It's like dodging and hitting mines in a minefield. I've lost numerous digits and limbs, and my hearing and sight are weakening. As the Black Knight quipped, "Tis but a scratch!"
When Norton Toolbar (for FF) is disabled, there are no, nada, nil crashes.
Windows 8.1
Firefox 39.0
Norton Security 22.5.0.124
Norton Toolbar (for FF) 2015.5.0.113
ALL are up-to-date as of today, 17 July 2015.
Note 1: I use Norton Safe Search but do not use Norton Vault.
