Firefox having CPU usage surges

Today--the day after a Windows security update--Firefox is having constant CPU surges that momentarily freeze my keyboard and mouse actions. I've restarted Firefox several times. It will happen even when only one tab is open and even on low-media pages. (It's taken me forever to type this paragraph because of the surges.)

== I turned it on this morning, the day after a large Windows security update

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

The problem stopped on its own about 2 hours after I posted, and has not resumed. I've saved your advice and will follow it if the problem comes back. Thank you!
