I noticed on the new tab content of Firefox, one of them is for a shady "xtra-pc" product (link goes to https://getxtra-pc.io/offer-01/) like the "finallyfast" optimizer from last decade.

Have not observed it myself and even if I disable all ads, pocket etc. so the chance that I catch it is zero.

However I do not think the user is a liar as there is nothing to gain for him.

I doubt HN community will respond much because they advocate Firefox. You see that because they close 10x more duplicates than with Chrome, Brave or for that matter any other competition.

I warn here directly everyone, I am not interested in sentiments and off-topic discussions, I want to reveal the truth, if you have nothing useful to add then just do not respond here or I will lock this thread. I make it that simple.
