-     * Real time binary checks with Google services are disabled (0412)

-     * You will still get prompts to update Firefox, but auto-installing them is disabled (0302a)

-     * You will need to make changes, and to troubleshoot at times (choose wisely, there is always a trade-off).
-       While not 100% definitive, search for "[SETUP". If required, add each pref to your overrides section at
-       default values (or comment them out and reset them in about:config). Here are the main ones:
        [SETUP-SECURITY] it's one item, read it
             [SETUP-WEB] can cause some websites to break
-         [SETUP-CHROME] changes how Firefox itself behaves (i.e. NOT directly website related)
+         [SETUP-CHROME] changes how Firefox itself behaves (i.e. not directly website related)
            [SETUP-PERF] may impact performance
-         [SETUP-HARDEN] maybe you should consider using the Tor Browser
+              [WARNING] used sparingly, heed them
-     * [WARNING] tags are extra special and used sparingly, so heed them
