I've updated the javadevelopment and shockwave flash plugins. These were the only ones that indicated it required updates. I ran these updates independent from the site and through the providers. Still appears to be a problem.

These problems do not occur in Chrome

Hello Ysbeer

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (or open the Firefox menu New Fx Menu and click the close button Close 29 ).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
  1. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

More information about reinstalling Firefox can be found here.

WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.

Please report back to say if this helped you!

Thank you.

Thank you for your suggestions

I've applied the first suggestion - on re-launching Firefox the first message that appears - the error message.

I've uninstalled Firefox and made Chrome my default browser - no problem for a week

Re-installed Firefox this morning - first message - the error message

Firefox does not allow file to open that use shockwave flash - I have the latest version and only one flash player.

Java development toolkit - I've downloaded the latest version and still a problem.

Is there a last resort?
