“Isn’t there a concern about the lack of security fixes sticking with an older version of a browser that isn’t updated?”
i personally think browser “security” is a shibboleth. It’s the job of the OS to provide security, not the individual applications. And yes, ALL versions of Windows provide horrible security, so one thing I do to vastly increase security is to emulate Unix-type security where one login ID is a superuser, and all the other logins are ordinary users that can use the facilities and applications provided by the OS, but cannot alter the OS or the applications. In Windows, this is done by having one account that has Administrative privilege and the rest are limited user accounts. One uses only limited user accounts for ordinary work and utilizes the administrative account only for OS and application add, removes, changes and updates. Fundamentally, this technique is the only one that offers any kind of security at all on a Windows OS.
“I can’t remember when I started having memory leaks/usage issues with Firefox.”
from day one. EVERY version of FF leaks memory like a sieve and the developers could care less, they’re too busy copying every bad feature possible from Chrome, Edge and Safari
Interesting comments about user privileges in Windows. I’d probably rarely need administrator privileges when doing ordinary surfing, so I may consider some changes. (As I said, though, I’ve never knowingly had a problem with viruses.)
I can believe that. It's just at some point in the past couple of years moderately heavy browsing with Firefox would cause the browser to crash or lock up the PC. This is on a Windows 7 Pro PC with at least 8GB RAM, No other application used on that PC causes it to lock up.
