Thank you for sharing your configuration,

It looks good.
Among the very first free software apps recommended to me when I'd first joined MalwareTips, besides LastPass, was Sandboxie.
If you don't know what a sandbox does, it's similar in the way a VM provides a layer of protection similar to that of a raincoat when you step out into the rain. All the wetness that accumulates on your coat is deflected and rendered temporary, so when you remove your coat you are dry underneath. Likewise, deleting the sandbox which encloses your browser deletes all changes including additions and updates. This protects your system from unwanted changes while clicking, and it is free.
Keep in mind when updating browsers or adding extensions to do these outside the sandbox.
