from AvoidTheHack:
Librewolf is an independent fork of Firefox that puts "user privacy, security, and user freedom first."
Librewolf is also the community run successfor to another defunct Firefox fork known as Librefox.
Librewolf is very similar to Ungoogled Chromium in the sense that Librewolf has removed Mozilla dependencies, services and telemetry from the browser.
For example, Librewolf does not come with Pocket integration like regular Mozilla Firefox. Librewolf also removes:
Google Location Services
Google as 1) the default search provider and 2) a search option
Mozilla telemetry, to include crash reporting and anonymous statistic collection
What's more is that one of the biggest draws to Librewolf is that it comes with a ton of already tweaked/configured settings that enhance user privacy and security. Some of these include:
Various privacy and security tweaks that overlap with various Firefox hardening guides - including the one published here on avoidthehack!.
This makes Librewolf more out-of-the-box privacy friendly for the average user.
uBlock Origin pre-installed
Extension firewall - extensions are limited in initiating their own connections
No "phoning home" or telemetry
Forced HTTPS on all websites (Read more about the importance of HTTPS)
Privacy friendly search engines (ex: DuckDuckGo, MetaGer, Qwant, and others)
Disables the saving of login information
Resists common fingerprinting techniques
doesn't appear to be portable for now as it left empty folders in AppData Local and Roaming on Win7 for me but there are requests for portable version in the issues section
