// LibreWolf override configuration, begins with samples from
// https://librewolf.net/docs/settings/
// Also incorporates some of https://aminda.eu/browser-extensions#firefox-aboutconfig

// Disable privacy.resistFingerprinting, use CanvasBlocker
// as requested to consider by LibreWolf documentation. Alternatively I think
// PrivacyBadger is enough considering it blocks canvas from third party sites.
// I consider Telemetry closer to voting than spying and I have no desire to
// vote for Windows NT as the universal operating system to be supported by
// everyone or English to be the only language in the world.
// Additionally I get migraines and suffer from floaters when staring at
// bright light screen so much and it's just easier to disable this than
// continuously click around Midnight Lizard or similar.
// Note that this also BREAKS Mobilizon through enforced UTC and thus all
// timezones will be three hours off unless caution is exercised. I am not
// sure if this also caused weird developery seeming errors about timezones.
