That's interesting.

Of course, I've heard of Google. Your Firefox might be loading a Google page.

Searches for "Functional Software" suggest that it is related to "Sentry" crash reporting components that may be used in Firefox for Android.

You are right sir, when I was using amazon on firefox then that time amazon was tracking. So should I depend on Duckduckgo to block the tracking attempt even in firefox or is there any in-built feature in firefox to block trackers itself?

Hi

This support article should help:

Thank you sir for helping. Enhanced tracking protection was set on Standard by default and when I switch to Strict then I not see any more tracking attempt by Google, amazon and functional software. Thank you so much Sir ☺️

Ummm when I enabled "Strict" option in enhanced tracking protection then it blocks tracking of all known tech companies like Google, Microsoft and Amazon and that is really amazing but still function software is tracking even Strict mode is enable. I don't know what is Function software and why it is tracking. Well it is not a major concern for me because Duckduckgo app tracking protection is blocking the tracking attenpt of function software which is enough for me. By the way I take screenshots of tracking attempt of function software. Hope you understand what I'm saying. Thank you ☺️
