Once I made Firefox my default browser, some of the documents saved on my desktop have the Firefox logo on them. When I opened the document, the top of the window has all of these "new tab" quickly and continuously running across the top, up to 131 before it stopped. So, how do I remove the logo from all of my documents?

What type of "documents"?

Firefox should only become the "default" for web-type documents, like saved HTML files.

With that many tabs opening rapidly, I suspect a setting in "applications" for Content Types is incorrect. See this: https://support.mozilla.org/en-US/kb/firefox-repeatedly-opens-empty-tabs-or-windows#w_change-the-action-for-a-content-type

If there is currently no file handler application that handles PDF files then the Firefox updater/installer registers Firefox as the default application to handle PDF files and thus they get a Firefox icon (Bug 452254). You can right-click a PDF file in Windows Explorer and use the open with dialog to change the default application to the Adobe Reader or your preferred application to handle PDF file. If the icon doesn't change to the icon of that application then you may have to change the icon on the desktop via other means.
