Isiphequluli sewebhu sikhululiwe Futhi IFirefox 68.4 yesikhulumi se-Android. Ngaphezu kwalokho, isibuyekezo senziwe ukwesekwa kwesikhathi eside . Uyeza maduze esiteji igatsha leFirefox 73 lizohamba, ukukhululwa kwalo kuhlelelwe uFebhuwari 11 (iphrojekthi amaviki angu-4 ).

- Kumodi yokuvinjwa ejwayelekile yokuqukethwe okungalungile ukuvikeleka ekulandeleleni umsebenzisi kusetshenziswa izindlela zokuhlonza ezifihliwe ("izigxivizo zeminwe zesiphequluli"), okwenziwa yi ohlwini lwe-Disconnect.me, oluhlanganisa abasingathi abatholakala besebenzisa imibhalo ukuze bahlonze okufihliwe. Ukuhlonza okufihliwe kubhekisela ekugcinweni kwezihlonzi ezindaweni ezingahloselwe ukugcinwa unomphela kolwazi (“Amakhukhisi amakhulu”), kanye nokukhiqizwa kwezihlonzi ngokusekelwe kudatha engaqondile, njenge , uhlu lwezinhlobo ezisekelwayo ze-MIME, imingcele ethile kumaheda ( и ), ukuhlaziya okufakiwe , ukutholakala kwama-Web API athile, aqondene namakhadi evidiyo ukuhlinzeka kusetshenziswa i-WebGL neCanvas, nge-CSS, ukuhlaziya izici zokusebenza nazo и .
- izindlela ngezicelo ezicasulayo zokunikeza isayithi izimvume ezengeziwe (Notification.requestPermission(), PushManager.subscribe() kanye neMediaDevices.getDisplayMedia()). Izicelo zokuqinisekisa ukugunyazwa ngeke zisaphazamisa ukusebenza nesiphequluli, kodwa zizoholela kuphela ekubonisweni kwenkomba kubha yekheli ngemva kokusebenzelana komsebenzisi nekhasi (ukuchofoza igundane noma ukucindezela ukhiye) sekurekhodiwe. Amasayithi amaningi ahlukumeza ikhono lesiphequluli lokucela izimvume, ikakhulukazi ngokucela izaziso ngezikhathi ezithile. Ukuhlaziywa kwe-Telemetry kubonise ukuthi ama-97% ezicelo ezinjalo anqatshiwe, okuhlanganisa nezimo ezingu-19% umsebenzisi avale ngokushesha ikhasi ngaphandle kokuchofoza inkinobho yokuvuma noma yenqaba.
- okokuhlola Iphrothokholi ye-HTTP/3 (ukuze wenze kusebenze ku-:config udinga ukusetha inketho ethi “network.http.http3.enabled”). Ukusekelwa kwe-HTTP/3 kuFirefox kusekelwe , ebhalwe ngolimi lwe-Rust, isebenzisa iklayenti neseva yephrothokholi ye-QUIC (HTTP/3 usebenzisa iphrothokholi ye-QUIC njengesithuthi se-HTTP/2).
- Ngokuhambisana nezidingo zomthetho osuqalile ukusebenza (I-California Consumer Privacy Act) ikhono lokususa idatha ye-telemetry kumaseva e-Mozilla. Idatha iyasuswa uma wenqaba ukuqoqa i-telemetry esigabeni esithi “mayelana:okuncanyelwayo#ubumfihlo” (isigaba esithi “Ukuqoqwa Nokusetshenziswa Kwedatha yeFirefox”). Uma usula ibhokisi elithi "Vumela iFirefox ukuthi ithumele idatha yobuchwepheshe neyokusebenzelana ku-Mozilla" elawula ukuthunyelwa kwe-telemetry, i-Mozilla phakathi kwezinsuku ezingu-30 yonke idatha eqoqwe ngesikhathi esiholela ekuhlulekeni kokudluliselwa kwe-telemetry. Idatha egcina itholakala eziphakelini ze-Mozilla phakathi nenqubo yokuqoqa i-telemetry ihlanganisa ulwazi mayelana nokusebenza kweFirefox, ukuvikeleka, kanye nemingcele evamile njengenani lamathebhu avuliwe nobude besikhathi seseshini (ulwazi olumayelana namasayithi avuliwe kanye nemibuzo yosesho ayithunyelwa). Imininingwane egcwele yedatha eqoqiwe ingabukwa ekhasini elithi “mayelana:i-telemetry”.
- Ku-Linux ne-macOS, ikhono lokubuka ividiyo ngemodi Yesithombe-Esithombeni lengeziwe, okukuvumela ukuthi ukhiphe ividiyo ngendlela yewindi elintantayo elihlala libonakala ngenkathi uzulazula esipheqululini. Ukuze ubuke ngale modi, udinga ukuchofoza ithiphu yamathuluzi noma kumenyu yokuqukethwe evezwa lapho uchofoza kwesokudla kuvidiyo, khetha “Isithombe esisesithombeni” (ku-YouTube, esingena esikhundleni somphathi wayo wemenyu yokuqukethwe, kufanele kwesokudla- chofoza kabili noma chofoza inkinobho ethi Shift icindezelwe).
- Uma ibha yokuskrola ibonakala umbala wangemuva wekhasi lamanje.
- ukubophezela kokhiye basesidlangalaleni (i-PKP, Ukuphina Ukhiye Womphakathi), okuvumela, kusetshenziswa isihloko se-HTTP Sokhiye Womphakathi, ukucacisa ngokusobala izitifiketi zokuthi yiziphi iziphathimandla zesitifiketi ezingasetshenziswa kusayithi elinikeziwe. Isizathu esibaluliwe isidingo esiphansi salo msebenzi, ubungozi bezinkinga zokuhambisana (usekelo lwe-PKP ku-Chrome) kanye nekhono lokuvimba isayithi lakho ngenxa yokubopha okhiye abangalungile noma ukulahlekelwa okhiye (isibonelo, ukususa ngephutha noma ukuyekethisa ngenxa yokugebenga).
- Ukuqanjwa ukuvumela ku-OpenBSD izingcingo zesistimu и ngesistimu yefayela eyengeziwe kanye nenqubo yokuhlukaniswa.
- Kususwe ukwesekwa kokuvinjwa kwezithombe ezizindeni ngazinye. Isizathu sokususwa ukuntuleka kwesidingo somsebenzi phakathi kwabasebenzisi kanye nesixhumi esibonakalayo esingalungile sokuvinjwa.
- Ekwakheni i-Windows, isici sokuhlola sisetshenziswe ukuze kusetshenziswe izitifiketi zeklayenti ezisuka esitolo sesitifiketi sohlelo lokusebenza olujwayelekile (inketho ye-security.osclientcerts.autoload kufanele yenziwe isebenze ukuze ikwazi ukukuvula kokuthi:config).
- Ukusekelwa kwezingxenye ze-CSS Shadow kunikwe amandla ngokuzenzakalela, kufaka phakathi ""kanye ne-pseudo-element"", okukuvumela ukuthi ubonise ngokukhetha izakhi ezicacisiwe ukusuka .
Isigaba
...ku-CSS ukuze ukhethe izinto eziboshelwe engxenyeni yesibaluli:
isakhi sangokwezifiso::ingxenye(isibonelo) {
umngcele: okuqinile okungu-1px okumnyama;
i-border-radius: 5px;
i-padding: 5px;
} - Kwengezwe ukusekelwa kwezincazelo , okukuvumela ukuthi uchaze indlela yezinto zokugqwayiza usebenzisa i-CSS ngaphandle kokusebenzisa ikhodi ye-JavaScript futhi ngaphandle kokuvimbela inqubo yokunikezela nokokufaka phakathi nokugqwayiza. Izakhiwo ze-CSS zinikezwa ukulawula ukugqwayiza
,
,
,
и
. - Izakhiwo ezikhethiwe zokuguqula i-CSS zinikwe amandla ngokuzenzakalelayo , и , engaboshelwe endaweni (okungukuthi ku-CSS ungakwazi manje ukucacisa “isikali: 2;” esikhundleni sokuthi “guqula: isikali(2);”).
- I-JavaScript isebenzisa u-opharetha wokuhlanganisa okunengqondo "", ebuyisela i-operand engakwesokudla uma i-operand yesokunxele i-NULL noma ingacacisiwe, futhi ngokuphambene nalokho. Isibonelo, "const foo = ibha ?? 'iyunithi yezinhlamvu ezenzakalelayo'" uma ibha ingasebenzi izobuyisela inani lebha uma kungenjalo, okuhlanganisa lapho ibha ingu-0 kanye ' ', ngokuphambene ne-opharetha ethi "||".
- I-API eyengeziwe kanye nomcimbi , okwenza kube nokwenzeka ukusebenzisa izibambi ze-JavaScript ukwengeza idatha efomini lapho ihanjiswa, ngaphandle kokugcina idatha ezintweni zokufaka ezifihliwe.
- API ibuyekeziwe ukuze ifane nencazelo entsha, isibonelo iqanjwe kabusha ngokuthi i-Coordinates to GeolocationCoordinates, Position to GeolocationPosition kanye
I-PositionError ku-GeolocationPositionError. - Ku-JavaScript debugger ukwesekwa kwama-breakpoint anemibandela (), okuqalwa lapho izici ezithile zezinto zishintshwa noma zifundwa.
- Ukuqalisa kwe-JavaScript debugger kuye kwasheshiswa lapho inani elikhulu kakhulu lamathebhu livuliwe (okokuqala, kuqala manje kunikezwa amathebhu abonakalayo).
- Idizayini Ephendulayo Imodi isebenzisa ukulingiswa kwamanani embobo yokubuka ye-meta ehlukene. Kwengezwe isifanisi senani esithi “prefers-color-scheme” kumodi yokuhlola ikhasi.
- В kumodi yokuhumusha ye-JavaScript enemigqa eminingi, kungezwe ukusekelwa kokulondoloza nokuvula amafayela kusetshenziswa izinhlanganisela u-Ctrl + O no-Ctrl + S.
- ukusetha i-javascript.options.asyncstack ukuze uhlukanise ngokubona imilayezo engavumelanisi kukhonsoli yewebhu. Uma wenza kusebenze izilungiselelo ze-console.trace() kanye ne-console.error(), inqwaba yekholi egcwele yemisebenzi evumelanayo iyaboniswa, okukuvumela ukuthi uqonde ukuthi uhlela kanjani ukwethulwa kwezibali sikhathi, imicimbi, izithembiso, amajeneretha, njll.
- Kumodi yokuhlola ye-WebSocket, ukuncozulula nokuboniswa okubukwayo kwemethadatha kufomethi ye-SignalR esetshenziswa kumilayezo ye-ASP.NET Core kusetshenzisiwe. Izibali nazo zengeziwe ezibonisa isamba sikasayizi wedatha ethunyelwe nelandiwe.
- Kuthuluzi lokuqapha umsebenzi wenethiwekhi kuthebhu ye-Timings ngokuhlukana ulwazi olumayelana nokuthi insiza ngayinye ifakwe nini kulayini ukuze ilandwe, ukuthi ukulanda kuqale nini, nokuthi ukulanda kuqediwe nini.
- Imvelo ekhishiwe kumathuluzi onjiniyela bewebhu , edizayinelwe ukuhlola ngekhodi ye-JavaScript (I-Scratchpad yathathelwa indawo ekukhululweni kokugcina imodi yekhonsoli yewebhu enemigqa eminingi).
Ngaphezu kwezinto ezintsha nokulungiswa kweziphazamisi kuFirefox 72, , okuyi-11 (eqoqwe ngaphansi и ) amakwe njenganamandla okuholela ekwenzeni ikhodi yomhlaseli lapho evula amakhasi aklanywe ngokukhethekile. Ake sikukhumbuze ukuthi izinkinga zememori, njengokuchichima kwe-buffer kanye nokufinyelela ezindaweni zememori esezivele zikhululiwe, kamuva nje zimakwa njengeziyingozi, kodwa ezingabalulekile. Okunye okuphawuleka ngokukhethekile udaba CVE-2019-17017 kukhodi ye-XPCVariant.cpp, engaholela ekusebenzeni kwekhodi.
