Sorry to hear about the crashes. The linked reports didn't immediately point me toward the cause of the problem.

Could you test in Firefox's Safe Mode? In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement? (More info: Diagnose Firefox issues using Troubleshoot Mode)

I did the safe mode prior to reinstall. It still crashes.

Can you associate the problem with particular sites or particular types of content? When I look at the comments submitted by other users with these two kinds of crashes, one points to Facebook and the other frequently involves Flash.

I suggest the following to minimize potential issues with Flash during your troubleshooting:

(1) To avoid unnecessary pain on sites where Flash is not actually essential, try setting Flash to Click-to-Play ("Ask to Activate"). This will delay Flash from starting on a page until you approve it.

To set "Ask to Activate", open the Add-ons page using either:

• Ctrl+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Plugins. Look for "Shockwave Flash" and change "Always Activate" to "Ask to Activate".

With this setting, when you visit a site that wants to use Flash, you should see a notification icon in the address bar and usually (but not always) one of the following: a link in a dark gray rectangle in the page or an infobar sliding down between the toolbar area and the page.

The plugin notification icon in the address bar typically looks like a small, dark gray Lego block. (If it's red, Flash needs updating.)

The delay in activating Flash can help distinguish between problems caused on initial page load, styling, and script activation vs. loading/running Flash.

If you see a good reason to use Flash, and the site looks trustworthy, you can go ahead and click the notification icon in the address bar to allow Flash. You can trust the site for the time being or permanently.

But some pages use Flash only for tracking or playing ads, so if you don't see an immediate need for Flash, feel free to ignore the notification! It will just sit there in case you want to use it later.

(2) The protected mode feature of the Flash player plugin launches independent external processes that need to be coordinated with the Flash plugin in Firefox. That has security benefits, but seems to have serious compatibility issues on some systems. You can disable it using the Add-ons page. Either:

• Ctrl+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Plugins. On the right side, find "Shockwave Flash" and click the More link. Then uncheck the box for "Enable Adobe Flash protected mode" and try that for a day to see whether it helps.

Thanks! I will give that a try. Crashes are mostly on Twitter & Facebook although also opening links to articles like on WaPo.

It also is not loading 'Doubledown Casino' on Facebook now but Chrome does.

Thank you for the new reports. The first, fourth, fifth, and sixth are Flash plugin crashes. Actually, there are only six reports of this specific crash signature, so possibly it is only on your system, which makes it very hard to research what might be going on, as there are no related bugs on file or comments from other users.

Other than the steps I mentioned before, you could refer to this article: Adobe Flash plugin has crashed - Prevent it from happening again.

The second and third reports are similar to the original one I looked at in this respect: on the Modules list, the first item is "_etoured.dll" which is a very odd name for a program. Most likely it's something from Nvidia, but I'm not sure whether it is something that you might need to work around, or remove, or something that just needs updating. This article suggests safe ways to check for updates to graphic-related software: Upgrade your graphics drivers to use hardware acceleration and WebGL.

_etoured.dll = NVIDIA Corporation
