Hm, amanqaku amahle. Ndingongeza: Ukuba uvula ithebhu entsha kwi-firefox, kukho injini yokukhangela ye-google ekhonjiweyo, ukuze ukwazi ukubona (kwaye usebenzise) loo nkonzo esekwe kurhwebo ngokulula. Kwaye bayawuxhasa lo msebenzi we-@google kwithebhu yabo ukwenza uphendlo olulula ngogoogle. Ngenxa yazo zonke la manqaku ndingawabeka kudidi lwaliwe. Ukunyuselwa (urhwebo) kukuthambeka okumtyibilizi, kuba xa sele uyenzile, uxhomekeke kuzo. Kwaye kungekudala okanye kamva uGoogle unokuthi kwi-firefox: Ndikunika enye imali ukuba undinike idatha yabasebenzisi bakho…

IFirefox nayo iyahlawulwa ukuze igqibe ukuba yeyiphi injini yokukhangela engagqibekanga emayisetyenziswe. Olu lurhwebo oluthe ngqo. Bafuna ingqalelo yakho 100%. Kunzima kum ukuba ndibhale iFirefox njengesimahla… https://www.investopedia.com/articles/investing/041315/how-mozilla-firefox-and-google-chrome-make-money.asp

IFirefox inyusa inkonzo yayo esekwe kurhwebo ePocket https://getpocket.com/premium kuzo zonke iithebhu. Bakwakhuthaza inkonzo yabo yokwabelana ngefayile enika iinketho ze-premium (ezihlawulwayo). Zilumkele ke ezi.

I agree with that, so 4 out of 5 blocks. As a side note you can opt out from that: in the Privacy & Security panel ->

Scroll down to the Firefox Data Collection and Use section and uncheck the boxes where it says “Allow Firefox to send technical and interaction data to Mozilla”

Firefox does collect some data but mostly for technical purposes https://www.mozilla.org/en-US/privacy/faq/ – so you trade some data to them.
