Recently when I launch Firefox, I get a New Tab with 9 tiles in front of my preferred start page; how do I stop this from happening?
My start page was set for the Firefox default start page. In the last few days whenever I launch Firefox I get a page that says "New Tab" in front of the default page I prefer. This is really annoying and I want to get rid of it but cannot figure out how to do that.

You're using the Enhanced version of the New Tab page which includes links to sponsored advertisers hand-picked by Mozilla in accordance to your site preferences.
You can change this by clicking the Gear icon on the new tab page and select "Blank" or "Classic." I myself use Blank.
You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.

Your System Details list shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts.
The user.js file is only present if you or other software has created this file and normally it wouldn't be there. You can check its content with a plain text editor (right-click: Open with) if you didn't create this file yourself.
The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can use this button to go to the currently used Firefox profile folder:

Windows hides some file extensions by default. Among them are .html and .ini and .js and .txt, so you may only see file name without file extension. You can see the real file type (file extension) in the properties of the file via the right-click context menu in Windows Explorer.
