Facebook has recently begun injecting a fbclid parameter into all outgoing URLs. This is, imo, a bit of a dick move. So this addon strips that param from all url requests.
What is nofbclid?
nofbclid is a Firefox add-on that eliminates the fbclid parameter injected by Facebook into outgoing URLs. It provides a simple solution to strip this unwanted parameter and enhance your browsing experience.
nofbclid is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install nofbclid if you trust the publisher.
nofbclid has earned a fairly good reputation and likely can be trusted.
