For you:
Firefox has released a patch for 10 vulnerabilies. Make sure that you see “Firefox is up to date” when you choose “About Firefox”. Now’s a good time to make sure that you’re updating your browser autmatically. In Firefox, choose Advanced from the Preferences page and then select the “Update” tab. In Chrome the updates are automatic and transparent. For Edge users, keep your Windows updates current.
