Browser

🐺 Librewolf

Add Arkenfox’s user.js:

• Make a new browser profile (in the urlbar): → about:profiles → Create a New Profile
• Place user.js in the new profile’s root directory.
• Place updater.sh & prefsCleaner.sh in the same.
• Set the new profile as default, restart Librewolf.
• Run both prefsCleaner.sh & updater.sh to update Arkenfox.

Alternatively, there is an AUR package.

Leave all site settings permissions at ask to allow. Check browser anonymity or security with TorZillaPrint & Browser Leaks.

See the Arkenfox wiki.

To restore the old UI:

browser.nova.enabled false

🦊 Fennec F-Droid

Fennec’s preferences are mostly the same as Arkenfox’s, or supplemented for by uBO. Otherwise, they’re not applicable as the features (or un-features) are not present. See my comparison of Arkenfox & Fennec.

The relevant about:config values are:

network.proxy.socks_port 9050
network.proxy.type 1 // 1 = enable, 5 = use system proxy
network.proxy.socks_remote_dns true // Set by Arkenfox

For I2Pd, replace 9050 with 4447.
