 * `0405` was not merged because it's inactive in the user.js. Instead the override was appended at the bottom.
 * `0801` was merged with the override, including the comment from the overrides file.
 * `4504` 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
 
-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 `7000: DON'T BOTHER`, 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:
-```js
-    user_pref("dom.netinfo.enabled", false); // 25xx - enforcing false -- prepended with a TAB
-/* !!! */ user_pref("dom.netinfo.enabled", false); // 25xx - enforcing false -- or a JS-multi-line comment
- 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 a pref, you have to use this **exact** format:
