Firefox 71 Will Not Work On My Windows 7 Laptop

more options

Hello everyone,

I have a similar problem to those mentioned in the discussions here...

https://support.mozilla.org/en-US/questions/1274248

https://support.mozilla.org/en-US/questions/1274407

..but the solutions given there do not help me here I am afraid.

We use Firefox with automatic updates switched on, on 3 systems here - 2 Windows 7 and 1 Windows 10.

Firefox has updated to 71 on all 3 systems.

The Windows 10 installation went without a hitch, but the 2 Windows 7 systems have had problems, although one has resolved itself somehow.

Unfortunately the update on my Windows 7 laptop has not gone well.

Firefox has become unusable on this system since the Firefox 71 update.

Firefox keeps crashing every time that I try to run it, showing a Windows error box stating "Firefox has stopped working and need to close" message, along with the following crash info...

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:	000000006fff150a
 OS Version:	6.1.7601.2.1.0.768.3
 Locale ID:	2057
 Additional Information 1:	312e
 Additional Information 2:	312e0f649e68df8b8010198c924de691
 Additional Information 3:	2e28
 Additional Information 4:	2e281e0f3e7e2e5b3bd20302d95cb119

I Cannot open in safe mode - it crashes immediately.

I have tried an uninstall/fresh install - still does not solve the problem.

I therefore have had to revert back to Firefox 70.0.1 to get it working again, and have had to switch off automatic updates until I can solve this problem.

Any help or advice would be much appreciated.

Thank you

Download the relevent 32 or 64 bit release of the previous version from the links underneath, select as per your language

32 bit at https://ftp.mozilla.org/pub/firefox/releases/70.0.1/win32/ 64 bit at https://ftp.mozilla.org/pub/firefox/releases/70.0.1/win64/

Should work fine, once installed go options disable automatic firefox updates for time being.

Hope it helps

By the way do you have a AMD ATI graphics chip/card ?

Hi there,

Thanks for your reply.

I have already reverted back to Firefox 70.0.1 last night, and have already turned off automatic updates.

Everything is working fine using that version, as it was before the Firefox 71 update.

In answer to your question - no I do not have an AMD ATI graphics chip/card on this problematic laptop.

It uses the built-in on-board Intel chip.

Thank you for your time and help.
