I'm not sure where to start on this problem, but my resources are being maxed out by either FireFox or Windows system since the last Windows update (or maybe the last Firefox update, not sure)

The Windows Defender antimalware service executable is sometimes involved as well, and System.  And sometimes even Task Manager.  But what happens is that the hard drive starts grinding and then  keeps working constantly and applications respond slowly or not at all.
I tried turning of multi-process in FireFox but that didn't completely solve the issue, so I turned it back on.  I also made an exception for Windows Defender because it was recommended in a microsoft article about Defender hogging resources  to stop Defender from being in a scanning loop. Apparently there was a problem with one of the windows updates that caused this issue for some.
C:\Program Files\Windows Defender\MsMpEng.exe 
So you can let me know if I need to remove this exception before going forward with any other changes.
I can sometimes restart FireFox and its fine for a while, and other times I restart and its overloaded from the time it opens.
I tried browsing with Opera to day and  didn't experience any problems for about an hour and then there was a surge of activity that slowed things down again.  So now I'm not sure its totally FireFox related. Maybe just browsing with any engine related.
I'm hoping this is something simple. (as is always my hope. :) )

Did this happen the same time as you made this change to your browser??

Thanks Pete!   That was an easy way to get protection for this.

I'm pretty sure it was happening before that, as when I added the list I wondered if it might be cryptomining that was causing the the hard drive to be working all the time.
I've disabled most extensions except Ublock and a couple tiny ones last night and it seems to have helped some.  But then again, I got the resource overload after about an hour  using  another browser that doen't have anything added to it.

So I disabled Ublock, but the Windows Defender Antimalware Service Executable is still working away, usually taking up to 50% of the CPU.  Desktop window manager seems to be working hard as well (around 10%), along with System, running at about 25%.

Firefox with one window open is running between 10-40% CPU  at 400-800MB memory  and 5-6 processes.

Is it possible that Dell patched your bios for Spectre and Meltdown while you weren't looking?

One of the reasons I'm adding things to uBlockOrigin, and getting rid of stand alone add-ons like AdblockPlus and NoCoin, is that I'm attempting to minimize the number of add-ons, after the Dell patch slowed things down.

My situation isn't as crippling as yours appears to be, but I definitely don't have the performance I had before.

How could I tell?


One of the things I read was something to try was to install another antivirus so that Defender will turn itself off. I'd rather not replace Defender if it can be fixed, but what do y'all think about this idea?

I've switched to Opera browser as a temporary measure.   Its a lot quieter in hard drive land, at least for now.  I would  use Pale Moon if I could import bookmarks.

Why can't you import bookmarks to Pale Moon?  Export your Firefox bookmarks as an HTML file and then important that HTML file to Pale Moon.

By the date.
The "Specs" you have linked in your signature indicate..

BIOS Version/Date   Dell Inc. A09, 3/11/2008
If you check your "System Information" now, a date in 2018 would indicate they've been updated.
If it still shows 2008, they haven't.

@ Pete!   I checked. BIOS version is the same - 2008

@Corrine:  wut?   I thought with one of the PM updates, FF profiles could no longer be imported, and I thought that meant bookmarks too.   I will work on this!  I will miss some extensions but I can adapt.  FireFox has just gotten so bloated and ridiculous with the constant updating. Its no wonder stuff is not working right.  Thank you for posting that.  OMGosh..I can keep my bookmark notes now. awesome.

I will check out the Dell Support assist. Any downside to installing it?  Can I do any damage by running it as a techno-feeb?

What does Dell SupportAssist do?

There are three main actions that you can take on Dell Support website that use the Dell SupportAssist application. When you take one of these actions, you will either be prompted to download and install Dell SupportAssist if it is not already installed or the application will automatically start and install the latest version before completing the action.

  1  Detect Product
    This is the most common use of Dell SupportAssist app. At various points on the Dell Support website, you have the option to have your product detected so that Dell can provide targeted support. When you click Detect Product, the application runs on your system and detects the Service Tag of your Dell computer. Dell then uses the Service Tag to look up product information, such as your original system configuration and warranty end date, to provide a product-specific support experience.

  2  Detect Drivers
    Once you have identified your product, you have the option to run a Detect Drivers (System Analysis) on the Driver & Downloads tab of the Product Support page. When you click Detect Drivers (System Analysis), Dell SupportAssist looks at which drivers are installed on your system and compares it with the latest available drivers. This is the most accurate way to determine which drivers are out of date on your system. Once the scan is complete, you can choose to "autoinstall" the updates with the Dell SupportAssist application. Similarly, Dell SupportAssist is used when you choose to download drivers from your downloads list or any time the driver size is greater than 2GB. For more information on Detect Drivers or System Analysis, refer to the Dell knowledge-base article Detect Drivers or Drivers by System Analysis.

  3  Run Diagnostics
    You also have the option to "Run a diagnostic" on the Diagnostics tab of the Product Support page to detect and solve common hardware and software problems. When you click Run Diagnostic, the Dell SupportAssist application acts like a bridge between the online and Dell SupportAssist application. Dell SupportAssist helps invoke Dell diagnostic tools (SupportAssist) in the right mode and manages the progress and communications protocol between the tools seamlessly.

Ever since I got this Dell computer, I've been wondering if I really needed DellSupportAssist or if it was just Dell bloatware. Every so often, it would run, but it didn't appear to be doing anything.

Earlier this year it did something. That's how I got the bios patch....
Mixed feelings, I'm now supposedly  immune from Spectre and Meltdown, but the computer isn't as fast ... Since I'm not a "gamer", and it can still run fast enough to stream movies, I'm putting up with it...... I'm still way ahead of when I ran dialup on Win98.

Granted, there are a lot of FF extensions that won't work with PM but, so far, I haven't had any issues and there are quite a few that have been "forked" to work with PM.  You may want to take a look at Pale Moon - Add-ons - Known Incompatible Add-ons to see the add-ons that have been fixed, forked, have work-arounds and those that won't be fixed.

For uBlockOrigin, you need version 1.16.4 and you also need the Pale Moon - Add-ons - uBlock Origin Updater.

A couple Pale Moon questions:

I have Adblock Latitude installed and it seems to be fine.  Is there any reason I should replace it with Ublock?

I have the 32 bit PaleMoom installed, even though I have a 64 bit machine, is that a problem?  I vaguely remember that I did that because there were super few extensions for 64 at the time, but maybe that has changed.

So, I had a brainstorm and decided to run the built-in Device and Hardware troubleshooter.
It found stuff and made changes to the computer, but  when I tried to view the details it didn't have anything more specific to report.  So I'm assuming maybe it updated drivers?    It advised a restart.
After the restart, I'm running FireFox again without all the disk chatter, System and Desktop windows manager  is back to normal single digit percentages and so is task manager.

Defenders Antimalware Service Executable still surges to 50+% CPU  just when I type something, although holds at about 50MB memory use, but all the disk chatter has stopped.

Disk and CPU are idling in single digits again.
Am I fixed?

(Note: I updated FireFox yesterday as well, but that didn't change anything)
