Thank you for your system information. I was a little alarmed to see Trovi among your home pages. It usually indicates a malware infection. Does that keep coming back? Not sure if it has any relation to the Flash problem, but... we may be able to help with that, too.

If you haven't already, you may want to disable the protected mode feature of the Flash plugin. It has security benefits, but is not compatible with all systems for some reason. You can do this by creating or editing a settings file.

The following pages/posts provide different approaches for that:

• Adobe support article under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

• Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209

• Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078

You may need to exit and start Firefox up again before this takes effect.

Any improvement?

You can also check if there are updates for your graphics display driver.

Thank you for your response, As I am not very computer savy I'm afraid I didn't understand a lot of what the articles offered. Your mention of the evil sounding Trovi frightened me so I uninstalled flash, cleaned out my computer, ran a scan and everything seems to be okay. I search my computer for Trovi and found www.trovi.com but cannot seem to delete it...however it doesn't appear anywhere that I can see. I just reinstalled adobe flash and I'm hoping for the best. Thanks! Pmorgan

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.
