Pale Moon 27.3.0 release notes: A major development update. Many things have changed in the media back-end, but please understand that some things are still a work in progress, and you may still encounter some html5 video playback issues with MSE.

Changes in Pale Moon v27.3.0:

  • Fixed up, checked and enabled vertical text writing modes!
  • Pale Moon will now be able to display vertical, right-to-left script.
  • Added the option to reset non-default profiles.
  • Fixed various issues in the WebP image decoder.
  • Added internally-supported document types to allowed types.
  • Fixed locale selection in ICU after update to ICU58.
  • (Note: Pale Moon uses the system locale for date formatting, not the browser locale)
  • Re-implemented the previous spellchecker dictionary logic (allow user override of document/element language, improve logic and make it unambiguous).
  • Ongoing fixes for the MP4 parser and MSE.
  • Made HTML Media Elements' preload attribute MSE-spec compliant.
  • The preload attribute on HTML media elements is now ignored in the case of an MSE source. This prevents an issue with sourceopen not firing when preload="none".

  • Fixed display of RSS folder icons.

  • 1 = refresh restored tab data from the network
  • 2 = refresh stored tab data from the network and bypass any cached data.
  • Improved upon a v27 performance regression with SVG scaling.
  • Improved performance by being more selective which CSS animations to process.
  • As a side-effect, elements changing their display from "none" to something visible now also animate.
  • Increased memory allocation for the use of very large PAC files.
  • Added menu entries for the permissions manager and improvements to its function and display.
  • Added preferences to control "highlight all" behavior of the find bar:
  • accessibility.typeaheadfind.highlightallbydefault = true/false highlight all found words by default.
  • accessibility.typeaheadfind.highlightallremember = true/false remember the last-used state of Highlight All.
  • Added devtools command-line options.
  • Added remote IP and protocol to Devtools->Network entry details.
  • Added support for
    and HTML tags.
  • Fixed a regression in the MSIE profile migrator.
  • Removed migration of browser-specific settings when migrating data from IE/Safari.
  • Implemented optional parameters for permessage-deflate in preparation for RFC7692 errata making acceptance of them mandatory (and to prevent web compat issues due to the current conflicting text of it).
