Mtundu watsopanowu umalola ogwiritsa ntchito a Firefox kuti aletse njira yatsopano yotsatirira mayendedwe ndikusintha mayunitsi otsatsa, omwe amachokera pakupanga gawo lapadera mu DNS mkati mwa tsamba latsambali. Ma subdomain omwe adapangidwa amalumikizana ndi seva yapaintaneti yotsatsa (mwachitsanzo, CNAME record f7ds.liberation.fr imapangidwa, kuloza ku tracking server liberation.eulerian.net), kotero kuti nambala yotsatsa imakwezedwa kuchokera kumalo omwewo monga malo. Dzina la subdomain limasankhidwa mu mawonekedwe a chizindikiritso mwachisawawa, zomwe zimapangitsa kutsekereza ndi chigoba kukhala kovuta, popeza subdomain yolumikizidwa ndi netiweki yotsatsa ndizovuta kusiyanitsa ndi ma subdomain potsitsa zinthu zina zapatsamba.

Mu mtundu watsopano wa uBlock Origin kuti mudziwe yemwe akugwirizana ndi CNAME anawonjezera zovuta kwa kuthetsa dzina mu DNS, lomwe limakupatsani mwayi wogwiritsa ntchito mindandanda yama block ku mayina omwe atumizidwa kudzera ku CNAME.
