In the past couple of days when I go to any shopping site such as craigslist, amazon, walmart, home depot the page loads correctly then a string of items for sale will appear above the normal list of items I was looking for. What got in that is causing this? Also, all of my search boxes whether Firefox or a different site tries to autofill or show search history but it doesn't look normal and has 2 buttons at the bottom "site search" and "web search". Help please.
