It kinda depends of your pc, only difference i can see is in ram being used, but still doenst matter because i sit at 60% ram usage while having browser, whatsapp, games, spotify, etc on...if you have cheap 200$ laptop, its total different caseFor me is paranoia. Sure is better to use filters for ublock but for normal user without happy click is paranoia. Never i used filters and never i had one problem. One ad blocker one extesion like bitdefender malwarebytes or avira browser safety and for extra extra protection netcraft you are super secure. And if you use Kaspersky free or forticlient or and Avast the last time you don t need anything accept ad blocker. Is my poor opinion . All the extra extensions killl the speed of your borwser .
For me the ublock origin is mandatory, i can live without other extensions because of avast web filter, bookmarks and safe browsing habits ( current setup)
Do i ever need netcraft or any other security/ privacy extension? Probably not
I would get rid of extension slowing me down or annoying me somehow, for sure
Were all different and we have own choises of extensions, browsers, antiviruses and other lifestyle
I still agree overkill should be avoided, but im not punishing myself or someone because he uses extension a or b
