I am speaking from only my personal experience, but I would say the vast majority of Firefox users are using Firefox to avoid Chrome and Chrome likes. That being said I would say they are then more likely and inclined to also utilize extensions.

According to Mozilla's own stats, most Firefox users do not have any extensions at all:

> 45.4%

Note that language packs are counted as extensions.

Some have disabled telemetry, of course, but how many? Here we can only rely on our own observations, and of all Firefox users I know, it's zero.

(I keep it enabled because I want my voice to be counted — people who have never lived in an autocracy tend to have peculiar views on this.)

I think the correlation of people using extensions and people disabling telemetry is pretty high. I do both myself. Even a decent password manager requires one (though not on android because it has an API for that). On android I do use others obviously.

Always appreciate people citing real data! I honestly would not have been able to guess one way or the other but unfortunately most comments are kind of hip firing in random directions that are impossible to keep track of, so it helps to keep these discussions grounded.

But what if you weigh this by usage time? The firefoxes without extensions might be hardly ever used
