A redesigned content blocking section in the site information panel (viewed by expanding the small “i” icon in the address bar) shows what Firefox detects and blocks on each website you visit. To learn more about content blocking, visit the Mozilla Blog.

A better experience for multilingual users: An updated Language section in Preferences allows users to install multiple language packs and order language preferences for Firefox and websites, without having to download locale-specific versions.

Support for Handoff on macOS: Continue browsing across devices. Pick up where you left off with iOS (via Firefox or Safari) on Firefox on Mac.

A better video streaming experience for 64-bit Windows users: Firefox now supports the next-generation, royalty-free video compression technology called AV1. Read about Mozilla’s contribution to this new open standard.
