Firefox uses unique identifiers to enable essential features like notifications, safe browsing, and performance improvements. These identifiers are small pieces of data unique to your browser that help Firefox remember specific settings, such as which sites you want notifications from or whether a website is safe. While they don’t include your name or email address, they are considered personal data as they are unique to your browser and support features that enhance your experience. Here’s a quick look at the main identifiers Firefox uses, along with a brief explanation of how each one works: __TOC__ {warning}'''Disclaimer''': Accessing settings in the [[Configuration Editor for Firefox|Configuration Editor]] (''about:config'') is intended for experienced or “power” users. These advanced settings can impact Firefox’s functionality and stability if changed incorrectly.
