I looked up "firefox addon usage" and this was the second result https://data.firefox.com/dashboard/usage-behavior

> over 40% of Firefox users have at least 1 installed add-on

Before they changed their ToS to allow selling my data I had spent the last 2 decades with telemetry disabled and adblocker installed

What’s the story on the TOS change? This is the first I’m hearing about it.

A while ago they changed their TOS from something along the lines of "We will never sell your data" to "Your data is safe"

Ublock Origin has 10,488,339 Users listed on it's Mozilla store-page at the moment, AdBlock Plus has 3,188,401 Users. And Firefox has surely still far more than those ~14 million users.

There was an article from Mozilla, some years ago, going more into the details about this, but I'm not sure where. Though, I found another one[1] from 2021, which starts with only one third of the users having installed an addon.
