While there is an add-on that can have Firefox open a link in Win IE [ Open in IE™ ] This should not happen by Firefox itself.

Finding that add-on without knowing the software of the add-on is not possible.

When IE opens, what is displayed? Same page, different pages?

Like I said, it happens mostly when Facebook tabs are open! It hasn't happened in over an hour, because I don't have any Facebook tabs open! IE DOESN'T OPEN ... can't anybody read these things? I told you, it's running in the background, and if you know computers, you'd know the difference between background and foreground. That browser is not opening ... it is running. It doesn't get started unless Firefox is running, then is opened by something connected to Firefox & Facebook without IE opening at all.

It might be the code sent by Facebook is doing this. Ask their support about it.

And what is in the IE windows?

There is no tech support for Facebook ... this is so why I don't like Forums! Can't anybody get to Mozilla anymore? If it were Facebook, this probably would've happened years ago. I've been using Firefox since 1998, and I'm quite afraid you don't know who you're dealing with over here, nor what's really going on! Could somebody else answer this, because this person keeps asking the same question I keep answering. Might be a reading comprehension thing. I've explained what IE is NOT doing; you just need to read it and understand what I'm talking about.

Firefox changes, and Facebook changes. Sometimes those changes cause problems.

I don't use Facebook and called for more help.

Sir, 'this person' is a volunteer contributor (like the majority of contributors here), a user just like you, trying to help other users in his spare time. A little appreciation wouln't go amiss, don't you think  ?

Quoting you :

How about typing in the address bar about:addons and then press
Enter  ? You should see your add-ons listed there, and who knows : the add-on that FredMcD mentioned in his first post, just might be there .......

I know we're all just users. I've been asking this for a very long time, and I'm very articulate that IE is not opening in a window, but merely running when Firefox starts it & Firefox freezes. Chrome doesn't do this at all, so this is being controlled by Firefox. I can't stand Chrome, so using that instead is not the solution I'm looking for. Task Manager is a Windows utility; that is what I use to see that IE has been started again. And, I only have 4 Add-ons, 3 Plugins, none of which say "open with" which is a Windows Explorer function or program properties item. Not Internet Explorer, but Windows Explorer file properties. So, when someone truly knows computers, then I most definitely will have something to appreciate. Otherwise, having this thing freeze up, and being told to contact people who don't exist, is a nightmare! We used to be able to send trouble-tickets to Mozilla. Otherwise, I've been getting the run-around for quite a while about this and I'm understandably frustrated. SIgh

Going over your initial post again, I think that it's not IE 'running in the background' that is your main problem, but Firefox freezing.

Would you be so kind as to take a look at this article :

Firefox hangs or is not responding - How to fix

Anything helpful there  ?

I just now noticed your thread here :

I am not happy  ! (no pun intended)

I don't know ... a gazillion more steps to go through. UGH. I know it's not resources, because I have plenty of everything (32gb RAM, internet provider speed, hard-drive space), and Firefox is not closing ... it just hangs. Only does this when multiple Facebook tabs are open. When I don't have FB open, this doesn't happen. Someone said to contact FB support. Obviously they don't use FB, because there is no tech-support and they don't address any kind of 3rd party software issue. Their lame reporting-system will just point fingers at Firefox; that's what all these companies do.

Chrome doesn't mysteriously open Internet Explorer in the background (no visible window for IE), as shown in the file I'm attaching. So, this is a nuance of Firefox. I just don't have all this time to do a million things to solve this! Been using Firefox since 1998, and this started over a year ago. I tolerated it until I couldn't anymore, and came in here looking for help ... since Mozilla no longer has an accessible tech-support. Because I used to work in software & hardware, my hunches are usually spot-on. Firefox is now doing something it didn't used to do, and spending hours doing all this stuff, usually makes me beyond frustrated, because I'm a very busy man who doesn't have a bunch of time to troubleshoot this thing endlessly.

Anyway...I will see what happens when I create an alternate profile. The other stuff doesn't matter, but how to get all my bookmarks & passwords back may become an issue with a new profile. I belong to hundreds of sites, have thousands of bookmarks, and my Norton Identity Safe cannot keep up with Firefox releases; doesn't work. Will let you know ... sigh

Yeah, I was having trouble getting logged-in, and once I did, couldn't remember how to get to older questions. Sorry, Happy112! You can forget the other one. I'm not happy, either. Don't know where I will find the time to do even more troubleshooting.  :(

I would like you to update your Video Drivers as they are from driverDate: 4-8-2015 If you have not done so already. Old drivers cause issues. If your Motherboard still has support on the manufactures site update it if you can,

Now this should only take 10mins or less to run while your doing something else. Please give it a try to repair any corrupted Windows System Files. Thanks Repair System Registry and Files

To run the SFC command use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin). Type "SFC /SCANNOW" (without quotes or copy/paste) and press Enter. For more information on using SFC, please refer to the Microsoft KB: Use the System File Checker tool to repair missing or corrupted system files

Run the Windows Deployment Image Servicing and Management (DISM) and System File Checker (SFC) tools as Administrator.

If something gets repaired, great and know your OS is fixed. SFC command fixes files from your cpu that are already there. DISM goes up to Microsoft and grabs new files and replaces corrupted ones.

See if that improves on anything and give a kindly yell back as we are all trying to help you.

Okay, done! Will tell you if this works. I usually go off Windows Updates for my video drivers, but I went to the site and got them myself.

Genius!!! That worked, and thank you for sparing my time. I honestly don't know how they got so out-of-date, but I'll keep my eye on those drivers from now on. I'm still scratching my head that I didn't see that during Windows Updates, but I am soooooooooo grateful & happy right now! WHOOP
