-With `-merge` it's best to always add a comment behind your overrides to make them easily noticeable when you compare your new user.js with one of your backups. A good way is to use the number of the pref's section. That will also make it easier to spot when a pref you want to override gets moved to a commented-out section like `9999: DEPRECATED` or `4600: RFP ALTERNATIVES`, resulting in your override becoming inactive, which may or may not be what you want. (see `dom.netinfo.enabled` in the example) If that's not what you want, you can prepend the `dom.netinfo.enabled` line with a TAB or JS multi-line-comment (or in v4.0 one or more spaces also works), like this:
+//// --- comment-out --- 'security.tls.version.max' -1202- wait until FF enables TLS1.3 for everyone
+```
+a couple things to note here:
+* 0103 was not merged because it's inactive in the user.js. Instead the override was appended at the bottom.
+* 0510 was merged with the override, including the comment from the overrides file.
+* 1202 was commented out and the original value and comment are kept intact
+* the netinfo line was merged but the pref has been moved to 4600 in the updated user.js (see info below)
+* the special comment-out command was also appended at the bottom as a reminder that you gave that command

  user_pref("dom.netinfo.enabled", false); // 25xx - enforcing false -- for v4.0 space(s) also works
 ```
+
+If you want the `-merge` function to comment out an active user_pref line you have to use this **exact** format:
+```js
+//// --- comment-out --- 'prefname.goes.here'
+```
+Anything after the closing single-quote is optional and can be used for comments/reminders. (see example above)
