MozillaFirefox63。0Beta(Quantum)已经发布,最大的改进来自于对Windows10的支持上,现在Firefox主题已经可以与Windows10实现明暗搭配,并且WebExtensions现在已经可以在Linux上运行。 macOS方面的改进就更大一些,WebGL电源首选项允许非性能关键应用程序和applet在多GPU系统中请求低功耗GPU而不是高功率GPU,这有助于省电,并且macOS上的运行效率,尤其是一直被诟病的标签页切换速度也得到了提升。 更新列表: New OnmacOS,WebGLpowerpreferencesallownonperformancecriticalapplicationsandappletstorequestthelowpowerGPUinsteadofthehighpowerGPUinmultiGPUsystems ImprovedWindows10integration:yourFirefoxthemenowmatchesyourOSDarkLightmode WebExtensionsnowrunintheirownprocessonLinux FastertabswitchinginthemajorityofcasesforourmacOSusers ImprovedthereactivityofFirefoxonmacOS Changed IntheLibrary,theOpeninSidebarfeatureforindividualbookmarkswasremoved Nevercheckforupdatesoptionremovedfromabout:preferences。Ifasubstituteisneeded,werecommendusingtheDisableAppUpdateenterprisepolicy Firefoxnowwarnsabouthavingmultiplewindowstabsopenwhenquittingfromthemainmenu。 TheCtrlTabshortcutnowdisplaysthumbnailpreviewsofyourtabsandcyclesthroughtabsinrecentlyusedorder。Thisnewdefaultbehaviorisactivatedonlyinnewprofilesandcanbechangedinyourpreferences ThebuildinfrastructureofFirefoxonWindowsmovedtotheClangtoolchain,bringingimportantperformancegains Developer Changesaffectingdevelopers
