I wonder if there is a comparable study for iOS apps? Or are there iOS versions of "Tinder, Spotify, Uber and OKCupid" better than the Android counterparts.

I have tried looking up Exodus but can't find any info. Anyone knows what this tool and how does it work?

Does anyone know why Firefox uses DoubleClick?

My suspicion is that this is a false-positive. If you go to about:config and search for doubleclick there is an entry called: browser.urlbar.doubleClickSelectsAll

Use is self-explanitory in the name.

This twitter thread indicates same:

Also, LeanPlum is explained here:

Quote:

Firefox for Android, Firefox for iOS, Firefox Rocket and Firefox Focus collect data about installations and retention using a third-party tracking framework called Adjust and Leanplum. This helps Mozilla determine the origin of the installation by answering the question, "Did this user on this device install the application in response to a specific advertising campaign performed by Mozilla?"

Having worked in a few agencies and departments that do both iOS and Android apps, whenever possible, they want parity between the two. So if the Android app is doing it, odds are better than not that the iOS app is also doing it to the extent allowed by Apple.

mobile dev here.

From my anecdotal experience I can tell you that whatever data we collect on Android we collect on iOS too (crashes, usage, etc) .
