I suggest you to downoad and re install the flash plugin using Adobe's test page (http://www.adobe.com/software/flash/about).
If the plugin is installed but may be disabled, you may face the problem. Check the plugin is enabled by going to Tools followed by Add-ons and check under the Plugin panel.
If you have already tried this method, then you may try resetting firefox by:
- Clicking on Help and then select Trouble Shoot Information
- Then click on Reset Firefox button on right-top corner
Hope it works for you!

Have you tried to Start Firefox in Safe Mode? {web link}
There is no 'help' button. I have "New Window", "New Private Window", "Save Page", "Print", "History", "Full Screen", "Find", "Options", "Add-ons", and "Developer". Which one should I chose?
It would be helpful if there were a "help" button. What do I have to do to get one of those?
Reset Firefox {web link} is a LAST RESORT ! !
Reset Firefox -- easily fix most problems
If you're having problems with Firefox, resetting it can help. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks and open tabs.
Open a new tab or window. type about:support in the address box and press enter. Or Press the Alt or F10 key to bring up the tool bar. Then Help > Troubleshooting Information.
Alt F10 does nothing.
