Web widget code - interception of traffic, to the layman, so that the third party does not embed the code, which services to choose (with https and 2FA, other tips)?

Question

Browsers

There are services of "start" pages like start.me, protopage.com, others. Web widget code - interception of traffic, to the layman, so that the third party does not embed the code, which services to choose (with https and 2FA, other tips)? What shortcomings of the service can be ignored, why? Thanks

Answer 1

It is better not to use such services at all, a big brother in the form of a browser that knows everything is enough.
I met almost all such services only when I turned off the adblock, and they opened as advertisements.
So it's a scam, or almost everything.
Why voluntarily in general is not clear to whom to give their data.
It is a bit safer to use a browser extension in this case, which is not connected to its servers, and stores everything locally.
Some set of words.
