As the web's most commonly used plugin, Flash is the most likely culprit. I'm not sure why the increased problems with Flash with the combination of Firefox 41 and Flash 19. I think people are working on that.

For the time being, 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) Consider rolling back to the extended support release of Flash 18. That one is getting security updates, and you can find it if you scroll down about half way on this page: https://www.adobe.com/products/flashplayer/distribution3.html -- it's the one for plugin-based browsers, either MSI or EXE format should work.

Most likely you would need to remove Flash 19 before that installer will work. This article has a link to the uninstaller: https://helpx.adobe.com/flash-player/.../uninstall-flash-player-windows.html.

Thank you for taking the time and sharing your knowledge to fix my problem.

Two days have gone by and no hangups. I will backup and go to flash 18 until 19 is sorted.

Thank you again
