The past few days I have not been getting the official site label when searching with DuckDuckGo. Somehow it is not showing this or it is not checking the security certificates. Additionally, for a few weeks, I keep getting a popup that wants me to: "Use DuckDuckGo as your primary search engine". DuckDuckGo has already been selected as my ONLY search engine. For a while I've used the Firefox add-on "DuckDuckGo Plus", but I removed it and still have this problem. I've read comments on the web that some people think this is a virus. So how do I find out if my version of DuckDuckGo is the real one and it hasn't been hacked? I tried to add an image for this question, but it didn't work. Additionally, I noticed in the details covering installed plugins, it states that I have installed Adobe Acrobat Plug-in for Web Browsers, Version 15.009.20077. I deleted everything from Adobe or so I thought. I no longer allow anything from Adobe on my computer. Is this part of Firefox 48.0.2 for Mac? And I don't have iPhoto6 installed.
