Clearing Firefox's cache and cookies still does not work.

被選擇的解決方法

Such a speed test usually uses the Shockwave Flash plugin. Your System Detail list doesn't include the list of installed plugins, so we can't see whether you have the Flash plugin installed.

You can find links of the latest Shockwave Flash player for Firefox on this page:

You can verify on the Adobe Flash Players Test Page that the Flash plugin is working and which version you have.

Hello ArnieB, 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 New Fx Menu , click Help Help-29 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.

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

SafeMode-Fx35

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension(maybe Norton Identity Safe ?). 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.

thank you

Yes. I re-installed Adobe Flash Player and that took care of my problem.
