Firefox 71 64 bit AppCrash on start up after updating

I've tried updating to Firefox 71 64 bit from Firefox 70.0.1 64 bit and ever since the release of the update to now I've been having the same issue over and over during startup. Even doing a clean install (which includes deleting the folders in AppData) I receive the same results. This is what I receive during startup when it crashes.

Problem signature: 

 Problem Event Name:	APPCRASH
 Application Name:	firefox.exe
 Application Version:	71.0.0.7275
 Application Timestamp:	5de4f320
 Fault Module Name:	StackHash_312e
 Fault Module Version:	0.0.0.0
 Fault Module Timestamp:	00000000
 Exception Code:	c0000005
 Exception Offset:	000000006fff0d9a
 OS Version:	6.1.7601.2.1.0.256.1
 Locale ID:	1033
 Additional Information 1:	312e

I have zero issues on Firefox 70.0.1. It's updating that's the problem and I know how to save my previous version to prevent full loss of my profile. I can't even go to safe mode or anything it immediately crashes on startup. When updating to ver 71 I only got 2 plugins which are adblock and a dark mode switch. As mentioned previous even deleting all folders including in the AppData and doing a clean install does not resolve this.

And before I'm told different, no, I do not have any viruses nor malware. I am on Windows 7 64 bit Ultimate. Everything is updated except my graphic card which is running on a RX 500 series using AMD software Advanced Micro Device version 19.12.1. I am on a Ryzen 5 2nd generation CPU on DirectX 11. This is the only program that I am having problems with.

It doesn't make sense for me to update my graphic card when it's technically updated (current version is 19.12.3) https://www.amd.com/en/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-560

Did something change in Firefox 71? I saw the notes but don't see anything I should be aware of https://www.mozilla.org/en-US/firefox/71.0/releasenotes/

Thanks if anybody helps.

Hi dREV, I've heard of folks having issues with the 64-bit version and then, everything works fine with the 32-bit.

Thanks for the quick reply.

Updated to the 32 bit and works out so far. Have firefox 70.0.1 64 bit backed up just in case. Wonder why the 64 bit version is wonky for some but not others.

Wrong day of the week ???

Hang on to your backup - good move - and I there's an update coming out Tuesday, version 72. Good timing, right?
