Firefox 65 released

Mozilla[German]Mozilla's developers have just released version 65 of the Firefox browser for Windows, Linux and macOS. This is a new major version that introduces new features.


I had already seen this information the day before, but my Firefox didn't find an update yet. Also blog reader Rudi K. had informed me by e-mail about the upcoming Firefox 65 version. Now I tried to let Firefox seach for update (via the menu and the help command About Firefox) and was offered the update for installation.

Firefox 65

The release notes dated January 29, 2019 führen do not list any security fixes, but some new features and changes:

  • Enhanced tracking protection: Simplified content blocking settings give users standard, strict, and custom options to control online trackers. 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 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.
  • Improved performance and web compatibility, with support for the WebP image format: WebP brings the same image quality as existing formats at smaller file sizes, which saves bandwidth and speeds up page load.

Firefox 60.5.0 contains also some (partly critical) security fixes. The Release Notes list the following changes:

  • Enhanced security for macOS, Linux, and Android users via stronger stack smashing protection which is now enabled by default for all platforms. "Stack smashing" is a common security attack in which malicious actors corrupt or take control of a vulnerable program.
  • Firefox will now warn you when closing a window (regardless of whether you have automatic session restore enabled for restart).
  • Easier performance management: The revamped Task Manager page found at about:performance now reports memory usage for tabs and add-ons.
  • Improved the pop-up blocker to prevent multiple pop-up windows from being opened by websites at the same time.

Firefox for Windows is now available with 32- and 64-bit MSI installers for easier enterprise deployments. You can download the browser here or on this selection page.

    Feels heavier, initiates as twice as long as the previous, not so fast already, release

    (I do not delete browser's history and such, so can relate)
