I have been having a problem recently. About a month ago I bought some stuff off of Backcountry.com an outdoors outfitter, and now when I go to other websites I am getting backcountry.com ads on websites, and just this morning I was looking to purchase some steel toe shoes and visited multiple website looking for a pair, and now I am getting ads for steel toed shoes on different websites. Do I have malware or something, i just did a scan with Malwarebytes and it came up empty. Can someone tell me what is going on, i don't want companies or websites tracking my purchases, it's really creepy. I am using the latest version of Firefox.
