I tried downloading the apk for firefox from https://www.mozilla.org/firefox/android/all/ but first I need to enter an email which I do not like having to do but ok I caved and did it. The email I recieved from mozilla did not contain a link to the apk. only a link to https://app.adjust.com/2uo1qc?campaign=email&adgroup=mobiledownload&creative=fx-mobile-en which got blocked by my security/privacy measures. Where can I get the apk from? preferably from f-droid. why is not firefox available on f-droid?
