Devil's Advocate says the people who make your browser reduce 100% to maybe 60%. Browser extensions are the 10%.

Depends on which browser and which add-on loadout you use.

On Firefox, with appropriate small changes and with uBlock Origin, uMatrix and a few other add-ons, you bet I can adequately control the data accepted by my browser.

If you use Chrome, well that's another situation. Don't use Chrome.
