We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.

1. Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
2. In that text field, enter %APPDATA% and press Enter. An explorer window should open.
3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
5. Open the most recent 5 files with a text editor and copy the IDs.
6. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!

You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Per your instructions, posting the only crash report in submitted there is:

Crash ID: bp-a606c654-0523-4ee0-b37b-8165b2130406

ok, thank you. unfortunately this report came back as empty & didn't contain any clues on what triggered the crash. you can also try to uninstall the real plugin again from your windows control panel / programs section...

Actually, there was a surprisingly simple way to get around the crash....click on a webpage link when firefox was not running, and when firefox loads up, close the window asking about the plugin confirmation.

Unfortunately, now I'm having trouble with Adobe Flash Player because it stop responding when playing videos. It's been updated to the most recent version, and Opera plays the same videos just fine. Any ideas?

You can check for problems with current Flash plugin versions and try these:

• disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
• disable protected mode in Flash 11.3 and later
• disable hardware acceleration in the Flash plugin
