Please refer the link: Adobe Flash plugin has crashed - Prevent it from happening again | Firefox Help
From the link you can try the options:
1. Disable hardware acceleration in Flash
2. Updating Flash
Please let me know if the above link resolves your issue.
It is what I've done, but still same issue after.
So I set Edge as my new web browser.
After that I decided to give another chance to flash in Firefox and that worked.
How can set another web browser as default app can resolve the flash issue in Firefox?
At least now it works.
So I put back Firefox as my new default web browser and flash still work, for now.
The major browsers don't want you to use 3rd party plugins anymore because plugins are a security risk. The shift is to move away from reliance on less stable 3rd party plugins to more stable native web APIs.
This is not a widespread issue. It's very likely something unique to your machine, but it's hard to say what's happening without logs or a crash dump. Flash Player runs in a sandbox inside of Firefox. The whole point of that is to ensure that in the event that Flash crashes, there's no way for it to take down the browser.
What that says to me is that there's something happening underneath us. Just as an illustrative example, maybe we're tickling an underlying hardware driver, which results in a failure that Firefox doesn't handle well and *it* crashes. We shouldn't be able to make the driver or the browser crash, by design. It might be something like a flaky disk or an actual hardware problem (bad ram, flaky motherboard, etc.).
Mozilla in particular has excellent, public telemetry, and a bunch of my old colleagues work there. If we were taking down Firefox on launch in a widespread way, I'd definitely be hearing about it. We have a pretty collegial relationship.
Normally, my first guess would be a corrupt Firefox profile, but you're doing a clean install.
All I can offer are some guesses:
If none of those help, an minidump would be super interesting. Hopefully Firefox is catching those quietly in the background, but if not, you may need to attach a debugger to get them.
Here are some articles on capturing crash dumps that might be useful:
