Mozilla Firefox 69 正式發布 提供進程優先級管理器功能

摘要:

Mozilla Firefox 69 正式發布,在完成測試Process Priority Manager之后,Mozilla現在在Windows版的Firefox 69上發布它,這樣一來,Firefox瀏覽器就能為Windows上運行的進程設置優先級,前臺運行的選項卡會被優先考慮,運行視頻和音頻的后臺選項卡也被視為“活動”。

New

  • Firefox now gives Windows hints to appropriately set content process priority levels, meaning more processor time spent on the tasks you're actively working on, and less processor time spent on things in the background (with the exception of video and audio playback).

  • To improve battery life on dual-graphics-card macOS machines, Firefox now tries more aggressively to switch back to the more power-efficient GPU for WebGL content when able. Firefox also works harder to avoid switching to the high-power GPU for one-off transient uses of WebGL.

  • Finder on macOS now displays download progress for files while they’re being downloaded.

  • Added support for the Web Authentication HmacSecret extension via Windows Hello on systems running the Windows 10 May 2019 update or newer.

Changed

  • As previously announced in the Plugin Roadmap for Firefox, the "Always Activate" option for Flash plugin content has been removed. Firefox will now always ask for user permission before activating Flash content on a website.

  • Firefox no longer loads userChrome.css or userContent.css by default. Users who wish to customize Firefox by using these files can set the  toolkit.legacyUserProfileCustomizations.stylesheets preference to true to restore this ability.

測試通道中部分用戶已經可以看到名為dom.ipc.processPriorityManager.enabled的進程優先級管理器功能的開關。從測試結果的反饋看,啟用了Process Priority Manager并沒有對瀏覽性能方面產生太大好處,也沒有變得更糟,但對系統資源的占用卻有了較大的提升。

Mozilla方面表示,降低后臺進程優先級,允許操作系統優先處理前臺選項卡這種工作方式值得一試,這樣前臺進程在需要時可以獲得更多處理器的時間。

需要注意的是,在播放媒體內容的標簽頁中,這一特性不會被啟用,因為Mozilla希望像YouTube這樣的網站在后臺繼續運行而不會中斷。

在運行Windows 10 May 2019更新或更新版本的系統上,新版通過Windows Hello添加了對Web Authentication HmacSecret擴展的支持。

蘋果系統方面,為了提高雙顯卡macOS筆記本的電池壽命,Firefox現在可以更加積極地切換回適用于WebGL內容的更高能效的GPU。 Firefox也更加努力避免切換到高功率GPU。macOS上的Finder現在會顯示文件下載時的下載進度。
