I think Ed Mullen misunderstood your question. That page
is about shutting off all the various functions that have been added to
make FF go online without asking. It's not about blocking IP addresses.

Ooops. Well, I *already* implemented the 30 suggested steps!

How to stop Firefox from making automatic connections
https://support.mozilla.org/en-US/kb...ing-automatic-
connections

1. Automatic updates and Security I already has set Firefox to "Never
check for updates".

2. Since I'm debugging why Firefox is slow, I already wiped out all
profiles and had recently installed the latest software, so there were no
addons.
Even so, I had already globally set addons to update only manually.

3. I had not thought about "blocklists", so I changed
extensions.blocklist.enabled;true to extensions.blocklist.enabled;false

4. I already had Firefox set to not "Block reported web forgeries."

5. I already had Firefox set to not "Block reported attack sites".

6. I had not thought about "signatures" so I changed
browser.safebrowsing.downloads.remote.enabled;true to
browser.safebrowsing.downloads.remote.enabled;fals e

7. I had tracking protection turned on, so I turned it off.

8. I had already turned off the setting to "Query OCSP responder servers
to confirm the current validity of certificates".

9. I had not known about the "network.prefetch-next"
setting so I changed it from network.prefetch-next;true to
network.prefetch-next;false

10. I just recently learned of Firefox DNS prefetching:
So I turned it off, changing network.dns.disablePrefetch;true to
network.dns.disablePrefetch;false

11. I changed the Firefox speculation from
network.http.speculative-parallel-limit;6 to
network.http.speculative-parallel-limit;0

12. There is apparently no way to turn off the Firefox prefetch of Addon
information if the Addons page is invoked; so I left that alone as there
are no addons.

13. I already had Firefox set to "When Firefox starts to Show a blank
page".

14. I have no extensions as I had wiped out my profiles and reinstalled
Firefox fresh on Windows.
But I checked and Extensions (add ons actually)
are set to manually update.

15. I never use bookmarks so the only bookmarks are those that Firefox
adds by default. There is no mention if any of those firefox default
bookmarks are "live bookmarks", but just in case, I deleted all the
bookmarks supplied by Firefox.

16. Unfortunately, I could delete all the garbage bookmarks that Firefox
installed *except* the useless bookmark named "View Pocket List".

*HOW DO YOU GET RID OF THE POCKET BOOKMARK?*

Changing this setting did not work:
browser.toolbarbuttons.introduced.pocket-button;true to
browser.toolbarbuttons.introduced.pocket-button;false

17. I have no unfinished downloads to prevent restarts.

18. I'm not using a custom search plugin.

19. I'm not using Firefox sync.

20. I'm not using "Firefox Hello - video and voice conversations online"
features. Nonetheless, I changed loop.enabled;true to loop.enabled;false

21. I had already set the new tab to open blank:
browser.newtabpage.enhanced;false

While I was there, I changed
services.sync.prefs.sync.browser.newtabpage.enhanc ed;true to
services.sync.prefs.sync.browser.newtabpage.enhanc ed;false

22. I changed browser.newtabpage.directory.source from
browser.newtabpage.directory.source;https://tiles.services.mozilla.com/v3/
links/fetch/%LOCALE%/%CHANNEL%
to browser.newtabpage.directory.source; a blank value

23. I changed browser.aboutHomeSnippets.updateUrl from
browser.aboutHomeSnippets.updateUrl;https://snippets.cdn.mozilla.net/%
STARTPAGE_VERSION%/%NAME%/%VERSION%/%APPBUILDID%/%BUILD_TARGET%/%LOCALE%/%
CHANNEL%/%OS_VERSION%/%DISTRIBUTION%/%DISTRIBUTION_VERSION%/
to browser.aboutHomeSnippets.updateUrl; a blank value

24. I set the browser.search.geoip.url from
browser.search.geoip.url;https://location.services.mozilla.com/v1/country?
key=%MOZILLA_API_KEY%
to browser.search.geoip.url; a blank value

25. I changed browser.startup.homepage_override.mstone from
browser.startup.homepage_override.mstone;47.0 to
browser.startup.homepage_override.mstone;ignore

26. I changed extensions.getAddons.cache.enabled from
extensions.getAddons.cache.enabled;true to
extensions.getAddons.cache.enabled;false

27. I changed browser.selfsupport.url from
browser.selfsupport.url;https://self-repair.mozilla.org/%LOCALE%/repair to
browser.selfsupport.url; a blank value

28. I searched for the media.gmp-gmpopenh264.enabled setting to set it to
false, but it did not exist.

29. WebRTC seemed extremely complicated, so I left it alone as the page
said not how to turn it off.

30. The browser.casting.enabled was already set to
browser.casting.enabled;false

Did I miss anything?
