Why doesn't Flash Player work on Firefox?

Recently, the newest version of Flash Player has stopped working on Mozilla Firefox. I reinstalled it, started Firefox in Safe Mode, and downgraded to version 11.7 of Flash Player.

I'm on Windows 8.1

Thanks!

OK! Let's take 7 steps ... an easy answer to a focus problem not a machine problem.

1.1. Download the Adobe Flash Player file version 14 at Adobe - Install Adobe Flash Player

1.2 or dowonload the above link: http://download.macromedia.com/pub/flashplayer/current/support/install_flash_player_osx.dm g

2.1 Double-click the AdobeFlashPlayerInstaller_14_ltrosxd_aaa_aih.dmg in your download folder

4. Do not double-click the red face (png file) - Installer "Install Adobe Flash Player".

5. Right click the face to perform a precise selection: Show Package Contents.

6.1 Select - Contents and double click; Select - Resources and double click; Select - Adobe Flash Player.pkg and double click.

6.2 Warning!! Select - Contents and double click; Select - Resources and double click; Select - app.bundle and copy it to your internet plugin folder (more work!!)

7. Select: Continue and complete your installation.

@Alexander,

You have posted the same exact (incorrect) MAC instructions on four different WINDOWS threads. Please read the thread before posting irrelevant information that doesn't provide assistance to the original issue.

Thank you.

I've been having this problem as well. I ran the uninstaller and reinstalled, no fix.

In Firefox, the player crashes for Youtube, and the browser crashes for Cracked.com video.

In Internet Explorer, the browser crashes on Youtube.

I've had to switch to Chrome, and I suspect Chrome only works because Flash is baked into it.

pawood88,

YouTube uses HTML5 video now.. it'll play even if you completely uninstall Flash Player.

IE uses the ActiveX plug-in. Firefox uses the Standard plug-in. The ONLY real difference between those two and Chrome's plug-in is that they are NPAPI and "PepperFlash" is PPAPI. Same plug-in, different architecture.

Try resetting Firefox: https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems

and repairing IE: http://support.microsoft.com/kb/318378

Also lookm into a "clean install" of Flash Player: http://forums.adobe.com/message/4041846

I'm fairly certain I have my Youtube account set to prefer the HTML5 player. However, the error message in Firefox is still that Flash has crashed.

I did everything the clean install instructions said before I joined this topic.

I just now tried to access the Firefox reset and Firefox crashed when trying to open the page.

I've had a lot of other problems recently (though Malwarebytes says my computer is clean), so I'm starting to suspect the problem isn't with any of the affected programs, but rather that I have a corrupted Microsoft update.

Firefox is about all I use. Six Windows builds (XP, Vista, 7, Server 2008, 8, 8.1) four OS X builds (10.6.8, 10.7.5, 10.8.5, 10.9.2)

Download these files:

Flash Player Uninstaller

Flash Player Plug-in (All other browsers)

Close Firefox.

Run the Uninstaller.

Run the Installer.

Reset Firefox. (https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems)

If it still doesn't work, try starting Firefox with Add-ons disabled, and re-enable them one at a time, beginning with Flash Player. When it quits again, you've found the plug-in that's conflicting.

I did the first steps you suggested, and Flash Player still did not work. I then restarted Firefox with Add-ons disabled, but I had no add-ons. I assume you were referring to plug-ins, but they were all activated as far as I could see automatically. So did you mean that I should deactivate all plugins, then reactivate them one at a time?

Edit: I deactivated all plugins, then reactivated solely Shockwave Flash 12.0.0.70. It still did not function, and it just crashed upon trying to watch a Youtube video.

Has anybody another idea? I'd like to get Flash Player working again.
