That is a good list. A couple fyi’s:
Firefox no longer supports javascript. Two workarounds: 1. Install earlier version of firefox, use just for those pages that need it. Unfortunately, means closing all tabs, closing current FF, launching older version. Or 2. Use chrome just for those pages, in another window. Set chrome to max privacy, disable javascript as default, enable one at a time only for pages needed. Yeah, PITA.
Startpage is great. Uses google websearch, but annonamizes you.
+1 on PIA VPN. It keeps zero logs, and assigns same IP’s to multiple annonymous users simulteneously. Plausable deniability. However, some websites block because so many hits from same IP’s = they think it’s spammers or DOS attack. FR was blocking PIA IP’s from US for a year+. So just pick server from, say, Japan to use.
Set Firefox settings to clear everything on exit. Also, only allow 3rd party cookies from originating site. Block all others.
Use multiple emails. Compartmentalize. I have over 8.
Use firewall router between cable modem and computer. Set router to act as dns server, to assign IP’s in your home LAN. (Don’t let cable modem do it)
IE takes forever to load and won’t play videos. I hung on with IE as long as possible but finally had to dump it.
Duck duck go doesn’t have current news articles. They’re always a week behind for me so dumped them. YMMV.
Firefox had too many annoying updates.
I figure they all gather everything on everyone so there’s no escaping.
more FYI:
Mozilla Foundation aka Firefox has probably been suborned by Google, a major sponsor. I use Safari, but another option is “Brave”. Major advertising-tech conventional wisdom is down on Brave because they block everything by default, then require explicit opt-in on ads and then only allow non-identifying ad-tech that plays by platform rules. This results in a very fast experience since most of today’s web experience is loaded with bloated ad-tech with an excess of privacy violating content...
