; Notes
- Firefox for iOS is not listed in this table as its version numbers would be misleading. Prior to version 96,{{cite web |url=https://support.mozilla.org/en-US/kb/whats-new-firefox-ios-version-96 |title=What's new in Firefox for iOS (version 96) {{!}} Firefox for iOS Help |website=mozilla.org |publisher=Mozilla Foundation |date=January 11, 2022}} it used version numbers distinct from other Firefox versions, which share the core Gecko rendering engine. The iOS app uses the operating system's rendering engine (WebKit), rather than Mozilla's (Gecko).
