Don try that Idiotic Applications. I have installed it on My Laptop for the Purchase of Redmi 2 times in 14 days on 2 different W ebsites . They want to get the data from your system. After thati uninstalled it and tried without having those Extensions and it got worked for me 3 times first for REDMI 5A on Flipkart and second for D which is Amazon Flash sale phone on Jan18 and nowYesterday Infinix Hot S3 that too in a flash sale. I am telling you just clear the temperory files on your system and try it on the website99% chances is if you have a strong internetmection like i have USED Jio hotspot from my phone to laptop.I think if you tried it on App you will not get thattry it on Laptop. Try it!!!!
