Off topic but does anyone know how to shut off the update notification, its just an annoyance but it does pop-up frequently.
IMHO, users can delay some updates as long as they:
A) DO NOT click on links in e-mail messages.
B) DO NOT click on links in text messages.
C) Keep an eye on: https://www.howsmyssl.com/
Re links - copy the link, paste it into a text editor window, examine for "Does this look legit?", then paste into the URL address field of your Internet browser.
Sometimes, I paste into the Startpage.com search engine's search field, then click Enter/Return, and in the results list, choose the "Visit in Anonymous View" <- so you can view the website via the Startpage.com proxy feature.
I’ve been using these scripts for several months now and have gone thru a couple of FF updates with no issues.
