It may be helpful if you could share a few more crash report IDs to see whether there is a consistent pattern or it's more random.

When I research issues with the DLL mentioned in that crash report (msvcp140.dll), there are indications that some users may need to update their version. However, I have no idea why that might be needed in your scenario. Perhaps a program that intercepts and tries to record or download videos requires a new version?? Anyway, the latest version seems to be the last file on this page:

"Microsoft Visual C++ Redistributable for Visual Studio 2017" https://www.visualstudio.com/downloads/#microsoft-visual-c-redistributable-for-visual-studio-2017

I have not tried that myself.

Thanks jscher2000. These are the other crash IDs. Generally Gah errors with media such as streaming radio and youtube. There was once with interactive banking login.

Any help much appreciated. Should I uninstall and reinstall? Mozilla is up to date it appears.

I would suggest to uninstall Flash first, as it appears to be version 16 which is very outdated and insecure. Do not update/reinstall Flash yet, but check whether the crashes occur first.

If they do not, you can (but don’t necessarily have to) install the most recent Flash Player and see if the crashes reoccur. Personally I would not install Flash yet at this point.

If Firefox still crashes, try updating your graphics drivers from here. The 15.40.36.4703 version listed as latest should be 20.19.15.4703. A previous but newer version than your current one mentions fixes to crashes in some applications in its release notes. You may have better results with that version if the latest one also has issues for you.

If everything is OK, reinstall Flash if you really need it.

Two of these crashes have the signature "igd10iumd64.dll | UpdateColorsStub" and one is "igd10iumd64.dll | ntdll.dll@0x2a2b5". Since the crash occurred interacting with the Intel graphics drivers, we generally suggest this article as the first step toward a solution: Upgrade your graphics drivers to use hardware acceleration and WebGL.

Edit: The link by Tonnes to Intel's site may be more up-to-date than what Microsoft and your PC manufacturer offer, just make sure to check the model numbers and 64-bit compatibility.

These two crashes have the signature "CAudioClient::FinalRelease" and 92 reports have been submitted in the past 7 days. Most likely these are caused by a programming error affecting a small number of systems running 64-bit Firefox on Windows 8-10. A fix was just developed but it is very unlikely to be incorporated into Firefox 55 at this point; it could still be included in Firefox 56 due out in about 6 weeks.

For now, you could consider switching back to 32-bit Firefox. Although this article refers to switching in the other direction, the steps are similar: How to switch from 32-bit to 64-bit Firefox.
