How can I disable unsolicited Firefox web requests (e.g. "detectportal.firefox.com", "getpocket.cdn.mozilla.net", "snippets.cdn.mozilla.net")?
I noticed that when Firefox starts, numerous websites are queried:
- GET http://detectportal.firefox.com/success.txt - GET https://content-signature-2.cdn.mozilla.net/chains/remote-settings.content-signature.mozilla.org-2020-08-15-15-04-50.chain - GET https://getpocket.cdn.mozilla.net/v3/firefox/global-recs?version=3&consumer_key=40249-e88c401e1b1f2242d9e441c4&locale_lang=de&count=30 - GET https://search.services.mozilla.com/1/firefox/78.0.2/release/de/DE/default/default - GET https://firefox.settings.services.mozilla.com/v1/buckets/main/collections/ms-language-packs/records/cfr-v1-de - GET https://snippets.cdn.mozilla.net/6/Firefox/78.0.2/20200708170202/WINNT_x86_64-msvc/de/release/Windows_NT%2010.0/default/default/ - GET https://snippets.cdn.mozilla.net/us-west/bundles-pregen/Firefox/release/de/default.json - GET https://push.services.mozilla.com/
I tend to regard these as unsolicited and violating my privacy.
How can I disable all these requests?

The detectportal one is related to the
network.captive-portal-service.enabled preference, which some networks use. You should be able to disable it by setting that preference to
The search one provides updates for the search engines in Firefox based on the locale that you are using in Firefox.
The firefox.settings one, I believe is used for Firefox sync.
The snippets ones comes from the homepage item conveniently called "Snippets". It just displays messages and information from Mozilla. The visibility of the item can be set in the Firefox settings Home section.
The getpocket one comes from the homepage item called "Pocket". You should be able to disable it by setting the
extensions.pocket.enabled preference to
The content-signature one is used for CDN connection and certificate verification. See this page for more info.
The push connection is related to Firefox update checks and the notification push service.
The request for firefox.settings.services is to check for updates for asrouter.ftl.
I see this request when I open the about:newtab page.
