I haven't tried Librefox yet, but Internet privacy&security is a big interest of mine, and I'd like to suggest that another option to consider is Tor Browser.<p>Tor Browser is generally more privacy-focused than Mozilla, and the nicely integrated Tor support gives me a bit of privacy from my infamous ISP (VPN services tend to be sketchy, too).<p>Drawbacks to Tor Browser are that Tor itself is a bit creepy (e.g., presumably draws more attention to you from your own country's domestic surveillance), some news sites block US Tor exit nodes (whether they know it or not; Cloudflare seems to most often be the culprit), uBlock Origin is not part of the Tor Browser distribution (which means that people who add it lose some crowd anti-fingerprinting benefit), the NoScript part should really be replaced with uBlock Origin, Tor is much slower than direct, and the Tor or Tor Browser project could end/fizzle much sooner than Firefox does.<p>How I'm using Tor Browser currently is that I use it for sites that don't require logins or otherwise identify me. For sites that identify me anyway (e.g., banking, online ordering), I use Firefox. I don't use Firefox often. Keeping them separate also discourages me from logging into sites unnecessarily.<p>What I'd ideally like is for Mozilla to become more aggressive than Tor Browser about privacy -- not going to Tor, but doing things that would peeve much of the dotcom surveillance industry. This includes pushing privacy tweaks upstream to Web standards. Mozilla is perhaps the best positioned to play chicken with the dotcoms on this; most genuine privacy efforts would be simply broken by the sites, and lose their users. Mozilla has a lot of upper management, so presumably they could figure out how to peeve a lot of dotcoms, while still keeping the funding flowing.<p>(I should add that I use Tor Browser for only a casual, on-principle attempt at privacy from snooping companies. I <i>don't</i> believe that Tor or Tor Browser is sufficiently safe for many kinds of journalists and activists, for example.)
