• Rau Linux thiab macOS, muaj peev xwm saib cov yeeb yaj kiab hauv Daim Duab-hauv-Duab hom tau ntxiv, tso cai rau koj tshem tawm cov yeeb yaj kiab hauv daim ntawv ntawm lub qhov rais ntab uas tseem pom thaum taug kev hauv browser. Txhawm rau saib hauv hom no, koj yuav tsum nyem rau ntawm cov lus qhia lossis hauv cov ntawv qhia zaub mov uas tshwm sim thaum koj nyem rau ntawm daim vis dis aus, xaiv "Daim duab hauv daim duab" (hauv YouTube, uas hloov nws tus kheej cov ntsiab lus ntawm cov ntawv qhia zaub mov, koj yuav tsum yog- nyem ob zaug lossis nyem nrog tus yuam sij ua haujlwm nias).
  

• Thaum lub scroll bar tshwm koom nrog xim tom qab ntawm nplooj ntawv tam sim no.
• Rho tawm sijhawm Public key bindings (PKP, Public Key Pinning), uas tso cai, siv Public-Key-Pins HTTP header, los txiav txim meej cov ntawv pov thawj ntawm cov ntawv pov thawj twg tuaj yeem siv rau lub xaib. Yog vim li cas hais yog qhov kev thov qis rau txoj haujlwm no, kev pheej hmoo ntawm cov teeb meem sib raug zoo (PKP kev txhawb nqa txiav tawm nyob rau hauv Chrome) thiab muaj peev xwm los thaiv koj tus kheej qhov chaw vim yog khi cov yuam sij tsis ncaj ncees lawm lossis poob ntawm cov yuam sij (piv txwv li, yuam kev tshem tawm lossis kev cuam tshuam los ntawm kev nyiag khoom).
• Feem txais thaj ua rau thajtso cai rau hauv OpenBSD koom nrog hu xovtooj nthuav tawm ( ) и cog lus ( ) rau cov ntaub ntawv ntxiv thiab cov txheej txheem cais tawm.
• Tshem tawm kev txhawb nqa rau thaiv cov duab los ntawm tus kheej lub npe. Yog vim li cas rau kev tshem tawm yog qhov tsis muaj kev thov rau kev ua haujlwm ntawm cov neeg siv thiab qhov cuam tshuam tsis zoo rau kev thaiv.
• Hauv kev tsim rau Windows, ib qho kev sim ua haujlwm tau siv los siv daim ntawv pov thawj cov neeg siv khoom los ntawm lub khw muag khoom siv daim ntawv pov thawj (security.osclientcerts.autoload kev xaiv yuav tsum tau qhib kom qhib nws nyob rau hauv hais txog: config).
• Kev them nyiaj yug rau CSS Duab Ntxoo Qhov Chaw yog qhib los ntawm lub neej ntawd, suav nrog "ib feem"thiab pseudo-element"::qeb", tso cai rau koj xaiv tso saib cov ntsiab lus los ntawm Duab ntxoov ntxoo DOM.
