More interessting is the lose of ~60M users in the last 4 years. Peak in the data was at ~254M at beginning of 2019. Now it's at ~194M. The Hard lose continues.
Another notable point is that roughly 10% of the users have an adblocker, but 35%+ of users are using addons. What is the rest using?
It would be interessing to have older data for this, to see how the different stages of the XUL-addon-drama impacted those numbers.
A big part of the loss of users was when they lost the German market due to bad press after the Cliqz scandal in late 2017. They lost a lot of trust in Germany from that and Germany was one of Mozilla's most important markets due to how many privacy focused people there are in Germany
Not sure how something from 2017 impacts the numbers from 2019? And it seems that scandal was some months before the big switch to quantum, which should had significant more impact on the user numbers.
