Pale Moon - Release Notes****http://www.palemoon.org/releasenotes.shtml

  v28.3.0 (2019-01-15)

This is a major development and bugfix release.

Changes/fixes:

  • Added AV1 support for MP4/MSE videos. Please note that this is a reference library implementation and the upstream decoding lib currently has poor performance for higher resolutions (720p+). This is disabled by default; use the about:config preference media.av1.enabled to enable this codec.

  • Changed the API used for video playback with FFmpeg 58+. This should solve performance issues with VPx.

  • Redesigned the main toolbar icons as SVG images to make them HiDPI compliant.

  • Fixed the sync notification (infobar) icon.

  • Fixed a potential cycle collector resource leak.

  • Added icons and controls to tabs to indicate if sound is playing the tab and if so, allowing the user to mute it with a click. This is a native implementation of the API in use in Basilisk and performs the same function as the “expose noisy tabs” extension, although the extension may still be preferred by some for e.g. skinning capabilities. The feature may be disabled with browser.tabs.showAudioPlayingIcon.

  • Removed support for VR hardware.

  • Fixed out-of-bounds sizes for CSS calculation strings.

  • Removed the DirectShow component since it is no longer necessary.

  • Removed Firefox Accounts integration, phase 1: Changed the Sync client to the one from Tycho.

  • Made Sync optional at build time.

Stopped trying to cater to addons.mozilla.org since they no longer offer anything useful to Pale Moon after the Great XUL Extension Purge™.

Added an option to process favicons for optimal sized display and removing animations. Enable this with browser.chrome.favicons.process

Fixed an incorrect preference reference in feed reader.

Fixed an issue with lazy frame construction on display:contents elements. This should solve e.g. the use of mathjax in comments on stackoverflow.

Media code improvements and cleanup (ongoing).

Updated the DropBox useragent override to solve login issues.

Fixed potential crashes due to shutdown observers in VTT and font lists. DiD

Enabled some mistakingly-disabled optimizations in the JS JIT compiler.

Fixed several potential crashes in JS. DiD

Fixed several potential crashes in WebCrypto. DiD

Fixed a potential crash in JS Range Analysis. DiD

Fixed a potential crash in the layout engine due to combo boxes. DiD

Fixed a potential shutdown crash in non-standard environments related to 2D Canvas. DiD

Fixed a potential overflow in the PNG writer. DiD

Fixed a potential double-free in the MAR signing utility. DiD

Fixed an issue where URLs could be extracted cross-origin (CVE-2018-18494).

Updated NSPR to v4.20.

Updated NSS to 3.41, providing (among other things) full compatibility with the final version of TLS 1.3 on websites.

Updated location.protocol to the latest spec.

Updated Intersection Observers to the latest spec and enabled them by default.

Updated the SQLite lib to 3.26.0.

Fixed errors about the login manager’s recipeManager not being available (yet).

Switched status bar download arrow to SVG.

Fixed a crash in IntersectionObservers.

Fixed initialization of the Search service from browser code to avoid synchronous init.

Added logging of performance warnings to devtools consoles.

Fixed favicons in taskbar tab preview listings.

Blocked Comodo IS dll

Fixed issues in the HTML form submit observer module.

Limited resolving depth of CSS variables to a sane maximum (fixes cras.sh issue).

Removed Mozilla’s proprietary constructor on WebAudio’s AudioContext, aligning it with the standard specification.

Exposed the previously hidden preference in about:config for page thumbnail generation (some people prefer this for local privacy).

Aligned Element.ScrollIntoView with the DOM specification. This improves, among other things, compatibility with the React framework.

DiD This means that the fix is “Defense-in-Depth”: It is a fix that does not apply to a (potentially) actively exploitable vulnerability in Pale Moon, but prevents future vulnerabilities caused by the same code, e.g. when surrounding code changes, exposing the problem, or when new attack vectors are discovered.

なにやら一気に来た感があるっぱが about:config** で media.av1.enabledの項目を有効にするとたまにサポートしていませんと出るような動画ファイルの類再生できる様子っぱね　ただ720p以上（高解像度の動画）場合だいぶ負荷がかかるらしいので留意っぱよ？

その他のメディアファイルの再生の負荷軽減用の変更とかリークバグの修正・・

タブごとに音楽を再生している時、スピーカーのアイコンが表示されて、右クリックで音のミュートができるようになったかな？about:configの**browser.tabs.showAudioPlayingIcon**.から無効化もできるらしい

VRサポートや各種不要になったものを削除して…**Firefoxの本家ページがレガシーアドオン配布しなくなったのであちらへのアドオン更新時の照会やリンクを削除した様子だの 一応PaleMoonのアドオンサイトの方で使えるものもある （私的には、よく利用しているアドオンの作者ページはMemoを残しておいたほうがいいと思うっぱよ？すべて揃え直す場合に気に留めておいたほうがいいっぱ）

ファビコンのアニメーションやサイズ変更が嫌いな人用に about:config**にbrowser.chrome.favicons.processを有効にすると無効化できるらしい

あとは、バグ修正とセキュリティホール修正系の内容が主かの？**（いつものようにおいら大雑把だっぱが・・）

最近、本家のFirefoxもAdobeFlashを早めに無効化する話が湧いてた気がするっぱね… 「Firefox 69」で「Adobe Flash Player」プラグインはデフォルト無効化へ - 窓の杜 **https://forest.watch.impress.co.jp/docs/news/1164509.html 当面はあちらも手動で有効にできる様子だけどもFlashコンテンツを利用している方々や 過去のFlashコンテンツで好きなものや興味がある方はデータのバックアップやHTML5化等の移行・変換作業もそろそろ間に合わないギリギリの時期かもしれないっぱね？
