470k crashes / week

67k crashes / day

claim: "Given # of installs is X; every install must be crashing several times a day"

We'll translate that to: "every install crashes 5 times a day"

67k crashes day / 5 crashes / install

12k installs

Your claim is there's 12k firefox users? Lol

Based on what data? According to their reporting they have around 200 Million monthly users, which seems compatible with 470k crashes a week? See <https://data.firefox.com/dashboard/user-activity>

2% worldwide? https://gs.statcounter.com/browser-market-share

Granted, they're probably just as accurate as netcraft. /shrug

The nuance here is of cause that there are a bunch of people using multiple browsers. Also I mean there are a lot of people using browsers on the world

If 10% of firefox users are also iOS users, which is not unlikely, then those people get double-counted. In my case I probably use my phone and tablet for at least 50% of my web traffic, not counting youtube, which also skews things.

For my part I'm not sure I recall a crash having daily driven firefox in quite some time. I'd suspect that the large number of bit errors might be driven by a small number of poor hardware clients.

Wouldn't it be more likely the faulty machines are crashing pretty often.
