In your subject you stated you had tried safe-mode however in the message it does not mention you have. There is a specific way to restart in safemode as it disables all addon/extensions not to be confused with plugins in order to troubleshoot the problem.

See:

Troubleshoot Firefox crashes (closing or quitting unexpectedly)

sorry if I didn't post that but I have already tried that and everything else in the support for crashes before I posted this.

-> press CTRL + SHIFT + ESC keys to open Task Manager -> Processes tab -> right-click firefox.exe and click End Process Tree -> close Task Manager

-> Start Firefox in Safe Mode by holding down SHIFT key while starting Firefox

• As an alternative method, by using Win + R key combination and enter one of the following in the Windows Run box:
  • firefox -safe-mode
  • "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
  • "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode

-> Firefox Safe Mode window will appear -> DON'T SELECT ANY OPTIONS, just click Continue in Safe Mode

Your post shows the item MS2011Helper.DLL repeated over and over. Searching to find the owning application/process of that .dll file, the are many references on the internet claiming it to be malware.

Download, install and update as many of the following as possible until your infections are cleaned.

1. The free versions of these scanners will detect infections and clean your system; no need to purchase
2. Different malware scanners detect some malware that other scanners do not.
3. If you are unable to download the malware programs,
   • change the name of the installer program before saving the download to your hard drive, and
   • once installed, go to the installation folder for the program and change the name of the program executable file (i.e., for Malwarebytes Anti-Malware, change mbam.exe to xyz-mb.exe), then update the program and run the scan.
   • you may need to download on an un-infected computer, change the name of the installer program, copy the installer to a CD or USB thumb drive, and transport to your system for installation.
4. Some stubborn malware will need to be removed in Windows Safe Mode with Networking'. WARNING: Download all the tools first, then disconnect your modem before entering Windows Safe Mode, as your Firewall and AV/AS probably will not load in Windows Safe Mode. See:
