I have five privacy tools on this browser: uBlock Origin, Privacy Badger, HTTPS Everywhere, NoScript, and a free VPN. It was quite tedious to go through each of them before I figured out it was an HTTPS issue.
HTTPS is oppressive to those who cannot afford computers powerful enough to run the cyphers on so many connections. Try browsing on a 66mhz bus pentium some time.
The slowest pentium can do about 2 megabytes per second of AES+SHA. The fastest is more like 10. That should be more than plenty when compared to how long it takes to render the same amount of data.
And how much does that computer cost? An Arm SoC is not much...
