Qhov kev tso tawm tom ntej ntawm Chrome 86 thiab kev tso tawm ruaj khov ntawm Chromium tau raug tso tawm.
Cov kev hloov loj hauv Chrome 86:
- tiv thaiv kev xa tawm tsis zoo ntawm cov ntaub ntawv nkag rau ntawm nplooj ntawv thauj khoom hla HTTPS tab sis xa cov ntaub ntawv hla HTTP.
- Kev thaiv cov downloads tsis zoo (http) ntawm cov ntaub ntawv ua tiav yog ua tiav los ntawm kev thaiv cov ntaub ntawv tsis zoo ntawm cov ntaub ntawv (zip, iso, thiab lwm yam) thiab tso tawm cov lus ceeb toom rau kev rub tawm tsis zoo ntawm cov ntaub ntawv (docx, pdf, thiab lwm yam). Cov ntaub ntawv thaiv thiab ceeb toom rau cov duab, ntawv nyeem, thiab cov ntaub ntawv xov xwm yuav tsum nyob hauv qhov kev tso tawm tom ntej. Kev thaiv yog siv vim tias rub tawm cov ntaub ntawv tsis muaj encryption tuaj yeem siv los ua qhov phem los ntawm kev hloov cov ntsiab lus thaum MITM tawm tsam.
- Cov ntawv qhia zaub mov lub neej ntawd qhia txog "Ib txwm qhia tag nrho URL" kev xaiv, uas yav tas los yuav tsum tau hloov cov chaw ntawm nplooj ntawv hais txog: chij los pab. Tag nrho URL tuaj yeem pom los ntawm ob-nias ntawm qhov chaw nyob bar. Cia peb nco ntsoov koj tias pib nrog Chrome 76, los ntawm lub neej ntawd qhov chaw nyob pib qhia yam tsis muaj tus txheej txheem thiab www subdomain. Hauv Chrome 79, qhov teeb tsa kom rov qab tus cwj pwm qub raug tshem tawm, tab sis tom qab cov neeg siv tsis txaus siab, tus chij sim tshiab tau ntxiv rau hauv Chrome 83 uas ntxiv ib qho kev xaiv rau cov ntawv qhia zaub mov kom lov tes taw zais thiab qhia tag nrho URL hauv txhua yam.
- Txoj kev pib tshem tawm FTP kev txhawb nqa tau rov ua dua tshiab. Hauv Chrome 86, FTP yog neeg xiam oob qhab los ntawm lub neej ntawd li ntawm 1% ntawm cov neeg siv, thiab hauv Chrome 87 qhov kev cuam tshuam ntawm kev xiam oob qhab yuav nce mus rau 50%, tab sis kev txhawb nqa tuaj yeem rov qab los siv "--enable-ftp" lossis "-- enable-features=FtpProtocol" chij. Hauv Chrome 88, kev txhawb nqa FTP yuav raug kaw tag nrho.
- Nyob rau hauv version rau Android, zoo ib yam li cov version rau desktop systems, tus password manager siv ib tug check ntawm saved logins thiab passwords tiv thaiv ib tug database ntawm compromised accounts, tso saib ceeb toom yog pom muaj teeb meem los yog sim siv tsis tseem ceeb passwords. Daim tshev yog nqa tawm tawm tsam cov ntaub ntawv npog ntau dua 4 billion tus account uas tau tshwm sim hauv cov neeg siv cov ntaub ntawv xau. Txhawm rau tswj hwm tus kheej, tus hash prefix raug txheeb xyuas ntawm tus neeg siv sab, thiab cov passwords lawv tus kheej thiab lawv tag nrho cov hash tsis raug xa mus rau sab nraud.
- Lub pob "Safety check" thiab hom kev tiv thaiv zoo dua tiv thaiv qhov chaw txaus ntshai (Enhanced Safe Browsing) kuj tau raug xa mus rau Android version. Lub pob "Safety check" qhia txog cov ntsiab lus ntawm cov teeb meem kev nyab xeeb, xws li kev siv cov passwords cuam tshuam, cov xwm txheej ntawm kev tshuaj xyuas qhov chaw tsis zoo (Safe Browsing), muaj qhov hloov tshiab uninstalled, thiab kev txheeb xyuas cov add-ons siab phem. Kev tiv thaiv qib siab ua kom muaj kev kuaj xyuas ntxiv los tiv thaiv phishing, kev ua phem thiab lwm yam kev hem thawj hauv Web, thiab tseem suav nrog kev tiv thaiv ntxiv rau koj tus lej Google thiab Google cov kev pabcuam (Gmail, Drive, thiab lwm yam).

- Ntxiv kev txhawb nqa rau cov ntaub ntawv qhia ".well-known/hloov-password", uas cov tswv ntawm lub vev xaib tuaj yeem qhia qhov chaw nyob ntawm daim ntawv web rau hloov tus password. Yog tias tus neeg siv cov ntawv pov thawj raug cuam tshuam, Chrome yuav tam sim no qhia tus neeg siv nrog daim ntawv hloov pauv tus password raws li cov ntaub ntawv hauv cov ntaub ntawv no.
- Cov lus ceeb toom "Safety Tip" tshiab tau raug coj los siv, tso tawm thaum qhib qhov chaw uas nws lub npe zoo ib yam li lwm qhov chaw thiab kev tshawb fawb qhia tias muaj qhov ua rau muaj qhov tsis zoo (piv txwv li, goog0le.com qhib tsis yog google.com).
* Kev them nyiaj yug rau Back-forward cache tau ua tiav, muab kev taw qhia tam sim thaum siv cov nyees khawm "Rov qab" thiab "Forward" lossis thaum taug kev los ntawm cov nplooj ntawv yav dhau los saib ntawm qhov chaw tam sim no. Lub cache tau qhib siv lub chrome://flags/#back-forward-cache setting.
- Optimizing CPU cov peev txheej siv rau lub qhov rais sab nraud. Chrome xyuas seb lub qhov rais browser puas sib tshooj los ntawm lwm qhov rais thiab tiv thaiv kev kos duab pixels hauv thaj chaw sib tshooj. Qhov kev ua kom zoo no tau qhib rau qee feem me me ntawm cov neeg siv hauv Chrome 84 thiab 85 thiab tam sim no tau qhib txhua qhov chaw. Piv nrog rau kev tshaj tawm yav dhau los, kev tsis sib haum xeeb nrog cov tshuab virtualization uas ua rau cov nplooj ntawv dawb tshwm tuaj kuj raug daws.
- Ntxiv peev txheej trimming rau tom qab tabs. Cov tabs no tsis tuaj yeem haus ntau dua 1% ntawm CPU cov peev txheej thiab tuaj yeem qhib tsis pub ntau tshaj ib zaug hauv ib feeb. Tom qab tsib feeb ntawm kev nyob hauv keeb kwm yav dhau, tabs tau khov, tshwj tsis yog cov tab uas tab tom ua si cov ntsiab lus multimedia lossis kaw.
- Kev ua haujlwm tau rov pib dua ntawm kev sib koom ua ke Tus Neeg Siv-Agent HTTP header. Hauv qhov tshiab version, kev txhawb nqa rau Tus Neeg Siv-Agent Client Hints mechanism, tsim los ua ib qho kev hloov rau Tus Neeg Siv-Agent, tau qhib rau txhua tus neeg siv.
