Title: Firefox 160 Final Builds Posted to Mozilla’s Download Server, Official Launch Due November 10
Summary: Mozilla has published the final builds of Firefox 160 on its download server ahead of the release’s official unveiling on November 10, 2026, expected to be joined by the Firefox 153.7 and 115.46.0 ESR releases. The headline feature is Mini Window, which lets you lift a tab — or a selected page area — into an always-on-top window that floats above other work. Also new: Picture-in-Picture playback speed settings from 0.25x to 2.0x, as well as Matroska playback carrying FLAC, MP3 or PCM audio tracks. Other changes include dragging history entries from the sidebar into the tab strip, accessible MathML content in PDFs saved from web pages, a “Never allow” button to silence sites that repeatedly push mailto: and other external links into web apps, a contextual “Paste and Search” option in the address bar, and higher-contrast domain highlighting in the URL bar. Two notable fixes: no more dropped first character when typing quickly into the address bar or search bar, and no more multi-second freezes when signing in to intranet sites using NTLM or Kerberos (Negotiate) authentication. On Android, Firefox 160 enables Local Network Access restrictions by default, so websites must now request permission before connecting to devices on your local network. Firefox 160.0 binaries for Linux x86-64 and AArch64, Windows, macOS, and source are already present on Mozilla’s FTP server, timestamped November 9, 2026.
