The word "add-ons" and other words are highlighted in bright green-why?
Many random words are highlighted in lime green, which I can't undo. This is blocking Firefox from accessing website information. The words "add-ons", Mozilla, etc are typical words. Updating Shockwave might of started this problem.

Sounds like an add-on is doing that.
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
Also, you have two Flash plugins for Firefox: Shockwave Flash 22.0 r0 Shockwave Flash 13.0 r0 You need to get rid of the older one.
This is what I recommend ...
Adobe Flash is notorious for not always removing old Flash Plugin DLL files as part of a Flash program update. Sometimes the user needs to uninstall Flash completely and get a clean start.
First, grab the Adobe uninstaller from here: http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html
Then download the latest Flash Plugin version from here: Select the Windows > Plugin-based browsers - the EXE version. https://www.adobe.com/products/flashplayer/distribution3.html
Run the Flash uninstaller program, then reboot your PC. Then install the Plugin version of Flash. So you'll have a clean installation of Flash for Firefox.
Do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware. All these programs have free versions.
Make sure you update each program to get the latest version of their databases before doing a scan.
