The article suggests "The pair found that 95% of the data they obtained came from 10 popular browser extensions."
Given that the prime leakage of data seems to be browser extensions, why do you think the solution is to install more browser extensions? Do you have strong reason to believe that the ones you listed (especially adblockers) don't leak any data?
