firefox does not recognize flash player
I have version 19,0,0,226 of flash player installed. Shockwave 19.0 r0, and shockwave for director version 12.2 plug ins are installed and set to always activate. I have tried firefox 40 and 41 and it will not work with either version. (I went back to 40 until the Norton toolbar will work with 41.) If I right click on a shockwave video I do not get any information concerning shockwave. It is working on Internet Explorer. I did unistall using Shockwaves unistall program, rebooted and reinstalled and that did not solve the problem either. Start firefox in safe mode keeping shockwave active does not help either. Any suggestions?

I did not work again today. I found out through elimination that a plug in called Classic Theme Restorer was causing the problem, at least this time. I will see if that is the ultimate solution.

You can check the version of the current Flash player here:
Do you see the Lego block icon at the left end of the location/address bar if you visit a web page that uses a plugin?
If you use extensions (Firefox menu button/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions aren't blocking content.
Start Firefox in Safe Mode to check if one of the extensions (Firefox menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox menu button/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
OK. I give up. I have done this many times, started Firefox in safemode and it didn't help. After one more try, flash now worked in safemode. I restarted Firefox in normal mode without making any changes and flash now works. It has been an intermittent problem. I hope it stays fixed now. Go figure. Thanks for all your suggestions but I did them all before with no success but now it worked. You must have put some magic mojo in my PC. :-)

The Shockwave Flash plugin shows in the System Detail list, so Firefox must be finding it. Are there any message next to it?
You can check this plugin on the about:plugins page.
Try to delete the pluginreg.dat file in the Firefox Profile Folder and maybe addons.sqlite as well to reset the plugin registry databases.
See Re-initializing the plugins database:
You can use this button to go to the current Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
