All five are Flash-related crashes. If you haven't already, could you try the steps in this article: Adobe Flash plugin has crashed - Prevent it from happening again.

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

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.

jscher- Thank you so much for you quick reply. Unfortunately I've already tried all of the fixes listed in the article you linked as well as setting the Flash plug-in to "Ask to Activate". Firefox is still crashing. Sometimes on start-up, sometimes not until going to the websites I listed in my original post.

I'm just so frustrated, nothing is working! :( Do you have any other ideas for fixes?

Thanks for helping.

Did you try safe mode?

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

• Click the menu button , click Help and select Restart with Add-ons Disabled.

If Firefox is not running, you can start Firefox in Safe Mode as follows:

• On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
• On Mac: Hold the option key while starting Firefox.
• On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
  (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

When the Firefox Safe Mode window appears, select "Start in Safe Mode".

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Thanks for the reply tomatoshadow2, hubs was able to figure out the issue last night when he got home from work.

Window's installed a graphics card driver from 2011 the last time it did a Windows Update and it thoroughly effed up my whole system.

He installed the correct, up to date driver and then uninstalled and reinstalled both Flash and Firefox and then allowed Firefox to refresh itself (basically like a factory reset for Firefox.) All is well now. Thank you both for your quick and helpful replies, I really appreciate it!

Moral of this story? Pay close attention to the "Important" updates that Windows thinks you need. Don't just assume that since it says "Important" and is checked, that it's the right thing for your system. hahaha. Effing Windows Update.
