What are types of Firefox?

Firefox primarily comes in two main versions: Firefox (the standard version) and Firefox ESR (Extended Support Release). The standard version is updated frequently with the latest features and improvements, while Firefox ESR is designed for organizations that require stability and extended support without frequent updates. Additionally, there are specialized builds like Firefox Developer Edition, which includes tools and features tailored for web developers, and Firefox Nightly, a pre-release version that allows users to test the latest features before they are officially launched.
