Every version of Firefox since 62.0.3 has been unstable on my system to the point of being completely useless. The crashes I suffer from were clearly introduced in the transition from 62.0.3 to 63.0, because every version from 63.0 to 70.0 has been unusable, and every time reverting to 62.0.3 gives me back a working browser. (By 'unusable' I mean crashing literally within a few seconds of starting up).
However, 62.x is now so ancient that if I can't have a working version of Firefox soon I will have to give it up in favour of something more modern and secure!
Please can you investigate and fix this issue!

Can you please download Firefox 70, and let me know if it still crashes?
Hi Tyler, I did - and it is just the same as every other release from 63.0 onwards.
We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
- On the keyboard, press [Windows] + [R]. This should bring up a Run window that contains a text field.
- In that text field, type %APPDATA% and press Enter. An explorer window should open.
- From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
- Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
- Open the most recent 5 files with a text editor and copy the IDs.
- Paste each ID with bp- into the reply window on the forums.
Thanks in advance!
You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.
Did you try to disable hardware acceleration in Firefox ?
Try to start Firefox in Safe Mode to see if that works.
- Windows: hold down the Shift key while starting Firefox
- Mac: hold down the Options key while starting Firefox
You can also try the 32-bit Firefox version.
You can boot the computer in Windows Safe mode with network support to see if that has effect.
I have tried starting Firefox in 'Safe' mode and it made no difference. I tried disabling hardware acceleration and that made no real difference either. Here are some crash report URLs from this morning, with Firefox 70.
I don't think that the problem is Windows-related as all versions of Firefox up to and including 62.03 work fine, just no releases from then onwards.
One additional point that might be worth mentioning is that before they crash these later releases often seem to exhibit very slow/hanging TLS handshakes.

Looks like there's something wrong with the GPU.
Enter about:config in the URL bar and set gfx.webrender.all = false. Then restart the browser.
Couple more updates: The x86 version is no different to the x64 version - see https://crash-stats.mozilla.com/report/index/bp-754f204f-cf71-4218-9820-e05d30191023 and https://crash-stats.mozilla.com/report/index/bp-c3a01523-fba9-45e2-8087-4bb6b0191023
The parameter gfx.webrender.all was already set to false when I checked it.
When I get the TLS handshake hangs - which sometimes seem to be a precursor to a crash - I notice that there is one particular thread consuming 15-50% of my CPU.
Can you try a few things (these crashes are kinda all over the place so lets try a scattershot approach):
- Download Malwarebytes from www.malwarebytes.com, run a full scan, remove anything it finds.
- Update your graphics driver, Upgrade your graphics drivers to use hardware acceleration and WebGL
- Check for any Windows updates
- Finally, if you're still crashing, Turning off hardware acceleration
- Malwarebytes finds nothing - The Nvidia device drivers are already at the latest version (436.48) - Windows is also completely up to date - Hardware acceleration is already turned off
Thanks for your efforts, but still nothing to make a difference!
Two new Windows updates (KB4522355 and KB4522742) but still FF 70.0 crashes:
FF 62.0.3, of course, continues to work flawlessly!
Some programs are known to cause crashes in Firefox and other browsers. Check your computer and remove any malware or software that might be causing problems
