I just DL'd this newest edition I use Edge primarily, but I have used Opera, Chrome, Internet Explorer. I was surprised to find that FF warned me when signing in to PCPer forums, and reading their help link, they stated that our login's were insecure (I seem to remember that from long ago) anyway I said "The Devil might care..." and presto here I am and since "I don't live in Kansas anymore Toto ....." Those hackers can't get a lot of useful information about me from this site alone.
Anyway I like the NEW FF pretty well, it takes a few weeks to learn each browser's ropes so I'll reserve my verdict for a while.
