Log Message:
www/firefox: Update to 123.0

* For NetBSD, user-agent string reports as Linux.

Changelog:
New

  * We've integrated search into Firefox View. You can now search through all
    of the tabs on each of the section subpages - Recent Browsing, Open Tabs,
    Recently Closed Tabs, Tabs from other devices, or History.

  * Having any issues with a website on Firefox, yet the site seems to be
    working as expected on another browser? You can now let us know via the Web
    Compatibility Reporting Tool! By filing a web compatibility issue, you're
    directly helping us detect, target, and fix the most impacted sites to make
    your browsing experience on Firefox smoother.

Fixed

  * When translating web pages, we are now also translating text in tooltips
    (i.e. titles) and text displayed in form controls (i.e. placeholder).

  * Various security fixes.

Changed

  * Address bar settings can now be found in the Firefox Settings' Search
    section.

  * Improved PGO optimizations for macOS ARM64 and Android

  * Off-main-thread canvas on macOS, Linux and Android

Enterprise

  * You can find information about policy updates and enterprise specific bug
    fixes in the Firefox for Enterprise 123 Release Notes.

Developer

  * Developer Information
  * The Network Monitor now supports saving a response body to disk through the
    Save Response As context menu item. This replaces the Save Image context
    menu item, which only supported saving images.

Web Platform

  * We now implement linearRGB interpolation for SVG gradients, as well as the
    existing sRGB interpolation. You can choose which to use via the
    color-interpolation property.

  * Previously, SVG feImage elements that pointed to SVG content required the
    SVG document to have a root element that had non-percentage width and
    height values. Such content will now fall back to use the default replaced
    element values of 300px width and 150px height and the feImage will no
    longer fail to render.

  * By enabling Preload and Modulepreload support, Early Hints are now fully
    supported.

  * Audio echo cancellation can now be applied to microphone inputs when the
    audio output is redirected to another device with setSinkId().

  * Firefox now supports declarative ShadowDOM, providing developers greater
    flexibility and improved ergonomics when working with ShadowDOMs directly
    within HTML.
