in firefox ios Settings>"Send Usage Data" is enabled. "Studies" is enabled. it's my first iphone (15) and over the last 6 weeks swamped with new stuff to figure out but first weeks disabled everything i could to send out my data via IOS and all apps (firefox) and 90% sure i disabled these in firefox to find them now enabled. i've done 3+ IOS and firefox updates, does either go into our settings and re-enable them? is there a list somewhere so we know what to go back in an check after each update? i'm positive updating to IOS 17.4 it turned off my VPN without notification. the apple support told me IOS updates can change preference settings but doesn't know which and we have no control over it. yikes! thank you!
