Do I have multiple copies of Firefox running concurrently?
Two questions; First is why does the Taskbar show "Firefox (2)" (see first image) Second: When trying to troubleshoot, I open Task Manager, and with just one tab open, I see Firefox (13); confirmed when the line is expanded. What is going on here and is it impacting Firefox performance; see 2d and 3d images? (Phone camera photos as PrintScreen is disabled for Task Manager which doesn't seem smart)

It is quite normal to see more Firefox processes running.
- process for the main Firefox thread (user interface)
- one or more content processes
you see more content processes when Fission is enabled - process for the compositor thread
- process for extensions
- process for WebRender when this feature is enabled
You can find the current multi-process state on the Troubleshooting Information page (about:support).
- "Help -> Troubleshooting Information"
"Application Basics":
Multiprocess Windows and Fission Windows
"Remote Processes" (Web Content)
You can check the about:memory and about:processes pages for info about all processes. There are several toolkit.aboutProcesses prefs in about:config to show more info. See also the about:unloads page for info about the tabs.
