Pop ups in Chrome trying to have me install an application, how to find the root cause?
Cause of your problem is probably:


DNS injection in your network (check other devices, try setting DNS to 8.8.8.8 / 8.8.4.4)
Man in the middle attack in your network (check other devices, try enabling Data saving in Chrome settings)
weird unknown Chrome data corruption - try going to Settings->Applications->Chrome->Clear data &amp; Clear cache
Google Ads script injection - try disabling ad personalization as described in provided link
virus - use Malwarebytes Antimalware for Android


You can try:


using other browser
entering sites with HTTPS - try for example typing https://new.google.com/


EDIT: How to capture redirections using Chrome Developer Tools?


download Google USB Drivers &amp; ADB on your PC
plug your phone in
run adb devices, it should say your device is unauthorized
on your phone, you will get a window, select "Always trust this computer" and Yes
open Chrome on both your PC and phone
on PC, open Developer Tools on any page (f.e. about:blank)
select (hamburger)->More tools->Inspect devices...
make sure USB is checked
your device should appear on the left
run https://www.google.com on your phone (or any other working site)
on PC click on your device and select Inspect on your working tab
go to Network tab and select Preserve log checkbox
select Doc tab
navigate on your phone and see every HTML document your browser loads (it sometimes may go to Other tab)
