Firefox logo

Firefox 82 tshiab twb tso tawm lawm thiab nws tseem muaj rau rub tawm, ntxiv rau qhov hloov tshiab rau version uas muaj kev txhawb nqa ntev 78.4.0.

Daim tshiab no ntawm qhov browser los nrog kev txhim kho ntau yam ntawm qhov uas peb tuaj yeem pom tias muaj kev txhim kho tau ua los txhim kho lub kev yees duab saib kev paub.

Piv txwv, Hauv Daim Duab-Hauv-Daim Duab hom, qhov chaw thiab hom ntawm cov tswj khawm tau hloov pauv playback ua rau lawv pom ntau dua. Rau cov neeg siv macOS, cov keyboard shortcut (Option + Command + Shift + Right Bracket) yog qhib los qhib Daim Duab hauv Daim Duab qhov rai, uas ua haujlwm txawm tias ua ntej cov yeeb yaj kiab pib ua si. Windows siv DirectComposition rau kev txiav txim siab kho vajtse video kom txo tau kev siv CPU thiab txuas lub roj teeb lub neej ntev.

Rau txhua tus Windows 10 cov neeg siv nrog cov kho vajtse tsim nyog, WebRender composition tshuab, sau nyob rau hauv xeb, yog qhib los ntawm lub neej ntawd, tso cai kom ua tiav qhov kev nce nqi tseem ceeb thiab txo cov load ntawm CPU vim outsourcing ua haujlwm ua haujlwm ntawm nplooj ntawv cov ntsiab lus rau sab GPU.

Rau Linux, NVIDIA tsav tsheb nyob twj ywm rau ntawm WebRender block daim ntawvraws li Intel cov tsav tsheb thaum siv cov kev daws teeb meem ntawm 3440 × 1440 thiab siab dua.

Hauv Android, WebRender cav yog qhib rau cov khoom siv nrog Adreno GPUs 5xx (Google Pixel, Google Pixel 2 / XL, Oneplus 5), Adreno 6xx (Google Pixel 3, Google Pixel 4, Oneplus 6), ntxiv rau Pixel 2 thiab Pixel 3 smartphones.

Cov neeg siv ntawm NVIDIA Binary Tsav ntawm Linux lawv tau manually WebRender (gfx.webrender.all = muaj tseeb nyob rau hauv txog: config) thiab tsis txhob siv muaj pes tsawg leeg yuav regress, qhov twg sab saum toj ib nrab ntawm lub screen tiav lawm ua tus sau.

Qhov teeb meem no tuaj yeem daws tau los ntawm kev ua kom muaj kev sib xyaw los yog los ntawm kev xa tawm ib qho kev hloov pauv ib puag ncig hauv qab no: MOZ_GTK_TITLEBAR_DECORATION = system (hmoov tsis zoo rau lub npe qhov rai) lossis MOZ_X11_EGL = 1 (qhov kev xaiv no cuam tshuam WebGL 2 kev txhawb nqa).

Kev ua haujlwm tau raug ua tiav kom ceev nrawm rau nplooj ntawv thau khoom thiab txo lub sijhawm pib browser.

Ntxiv rau muaj peev xwm saib cov ntawv tshiab thaum txuag ib nplooj ntawv rau lub hnab ris Ntawm lub pob ntawm lub vaj huam sib luag: Ib qho lus sib tham tam sim no qhia txog kev xaiv ntawm cov khoom los ntawm cov xaib uas tau xaiv los ntawm lwm tus neeg siv hnab tshos.

Cov chaw teeb tsa uas tau sib sau ua ke ntawm cov khoom siv tau muab nthuav davCov. Piv txwv li, synchronization ntawm kev xaiv scrolling tau ntxiv, ntxiv rau on-screen keyboard nqis thiab hom duab-hauv-daim duab.
Hauv telemetry sau los ntawm Linux, tus kev suav cov ntaub ntawv hais txog ntawm cov windows subsystem protocol (Wayland, Wayland / DRM, XWayland lossis X11).

Media Session API qhib los ntawm lub neej ntawd, uas muab cov cuab yeej los txhim kho lub nris nrog cov ntaub ntawv hais txog kev rov ua haujlwm ntawm cov ntsiab lus multimedia hauv thaj chaw ceeb toom. Los ntawm cov qib API no, daim ntawv thov lub web tuaj yeem kho qhov tsos ntawm cov ntaub ntawv hauv thaj chaw ceeb toom, piv txwv li, tso cov nyees khawm kom ncua, txav mus los ntawm kab ntawv lossis mus rau lwm qhov muaj pes tsawg leeg.

Tsis tas li ntawd, nrog Media Session API, koj tuaj yeem ntxiv cov tuav dej rau cov xov xwm khawm uas qhib rau hauv thaj chaw ceeb toom lossis thaum lub vijtsam txuag tau.

Ntxiv rau kev nrhav thiab kab laum txhim kho, Firefox 82 tau txhim kho 15 qhov chaw tiv thaiv kab mob, ntawm cov 12 yog cim raws li txaus ntshai. 10 qhov tsis muaj zog (sau rau CVE-2020-15683 thiab CVE-2020-15684) yog tshwm sim los ntawm cov teeb meem nco txog xws li tsis tuaj yeem dhau thiab nkag mus rau cov chaw cim xeeb uas twb tso tawm lawm.

Cov teeb meem no tuaj yeem tsim kev kub ntxhov ntawm kev ua txhaum txoj cai thaum qhib cov nplooj ntawv tshwj xeeb rau cov nplooj ntawv.
