After updating to 56.0.2 my system and Firefox are slow and sluggish. Searches are slow. Scrolling often lags, as well as typing anything. Very annoying and unproductive. Have checked for any malware, etc. All drivers and applications are up to date. I did notice that one of my quad cores is maxed out and that the cpu speed is maxed out all the time. The disk seems to be more active as well.

I had these same symptoms on the last update, but discovered that Firefox downloaded the 32-bit version instead of the 64-bit. When I downloaded the 64-bit version it ran great. I thought at first that the same thing had happened, but unfortunately the current version says 64-bit.

I'm a novice. Any suggestions would be appreciated.

Win10 seems to have replaced your Video Drivers, Microsoft can and will replace your hardware drivers. https://www.howtogeek.com/302595/how-to-stop-windows-10-from-automatically-updating-hardware-drivers/ adapterDrivers: C:\WINDOWS\System32\DriverStore\FileRepository Not the usual place for them.

Check to : See if Multi-Processor Support is turned on. Multi-processor support feature may be disabled depending on your setup (it was for me) - you can check this by launching Firefox, then enter in "about:support" in the address bar; near the bottom, you should see a heading that says: "Multiprocess Windows", then look at the value next to it. If it says "0/1", then that means it's disabled. 0/2 and higher = on unless says it is off.

Then check the Task Manager and see how many instances of Firefox is running and what the memory numbers are like.

If need to can turn off multiprocessor : You can try to modify multi-process settings to see if this has effect. You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

set dom.ipc.processCount to 1 if it is currently set to a higher value (4) disable multi-process windows in Firefox

You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.

browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false
