@firefox part 1 i would like it if mozilla banded together most privacy focused and eco friendly services into itself so that it would be larger and have less dependency on google. Eg. Firefox browser + proton vpn and proton mail + ecosia search + treecard financial services + signal messenger and so on.
I believe what OP is referring to is that Mozilla/Firefox gets a significant payout for using Google as its default search engine - hence having integrations with other privacy-focused organisations that can assist with funding would be a plus - however since a lot of these are not-for-profit orgs, I dont think this is particularly viable.
