Unwanted installation or spyware on Firefox profile?
Is there some way something is installed on my profile (and saved on it so it keeps re-adding) without showing? I made a format on my pc. Prior to it and after it, I had refresh firefox to throw out any unwanted extension or plug in that it could possibly have. I downloaded firefox again and logged into my profile. Windows defender, avg or malwarebytes dont detect anything unusual to Firefox and myself either don't see anything unsusual or out of the ordinary. I checked extensions and plugins manually as well through the troubleshooting and didn't find something suspicious (I'm bad at programming so it's difficult for me to read the information it provides but from the simple things I don't see something that shouldn't be there).
I have a feeling though that something is wrong with Firefox. It's unusually slow on same device and not responsive many times. Like something is onto it. I've had recent attempts of someone trying to hijack accounts connected onto Firefox so I'm worried if it's something that I'm not seeing.
I can't find a support e-mail or live chat of Mozilla for someone from there to check it out.
Any help?

Does it make any difference if you test in Firefox's Safe/Troubleshoot Mode? In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.
If Firefox is running:
You can restart Firefox in Safe/Troubleshoot Mode using either:
- "3-bar" menu button > Help > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)
- (menu bar) Help menu > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)
and OK the restart. A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).
If Firefox is not running:
Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).
Note: Don't use the Refresh without first reviewing this article to understand what will be deleted: Refresh Firefox - reset add-ons and settings.
Any improvement?
I have already done this (and had to relog everywhere, redo settings, etc) already but it still seems off. That's why I asked if it something that can be "moved" (i don't know how to say this in tech words) through what's saved on my profile and not the installation. Because I made sure after the format I downloaded firefox clean from official mozilla page. And I did refresh it before starting using it
No, please do not Refresh again. Just restart in Troubleshoot Mode to see whether that makes any difference.
Malware and virus-type programs can get into most systems in many different ways. E-mail, installer programs, accessing a contaminated website . . . . .

Run most or all of the listed free to use malware scanners. Each works differently. If one program misses something, another may pick it up.
