Seems like my Control or Alt keys are "on" after browsing with Firefox and I have to control-click or alt-click on the desktop to set things back to normal
After a browsing session using Firefox, my system behaves like either the Contol key or Alt key is stuck "on". For example if I start clicking icons on my desktop, each one is highlighted and "added" as if I were holding down the control key while clicking on each one (thus selecting all the icons). If I physically press the control key and click, then click again without the control key down, the system then behaves as normal.

Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.
Start Firefox in Use Troubleshoot Mode in Firefox to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
