Troubleshooting

Flash works in Internet Explorer but not in Firefox

There are two different types of Flash Players: An ActiveX version for Internet Explorer and a plugin version for Firefox and other browsers. If you want Flash to work in Firefox you must install the plugin version, as explained above.

Flash-based video or audio does not play or stops after a few seconds

See Fix common audio and video issues.

Cannot view full screen Flash videos

See Flash videos won't play full screen.

Flash content shows as question mark

See Flash content shows as question mark.

Flash does not work properly and/or will not update

If Flash content does not work, acts strangely, or causes errors, or if you see a notice that you need to update Flash (e.g., at Mozilla's Plugin Check) even after installing the latest Flash version, see Flash does not work properly or will not update.

The Adobe Flash plugin has crashed

If you see this message instead of Flash content in Firefox 3.6.4 or above, see Adobe Flash plugin has crashed - Prevent it from happening again.

Firefox crashes when viewing YouTube videos

If Firefox crashes when viewing YouTube videos or other Flash content in Firefox 3.6.3 or below, see Firefox crashes when viewing Youtube videos.

Flash does not work in Firefox 4

Starting in Firefox 4.0 Beta 7, Firefox will run as a 64-bit application on Mac OS 10.6 "Snow Leopard" and requires at least Flash 10.1 for Flash to work. If you have an older version of Flash installed, you should update Flash to the latest version. If you have an older Mac that you upgraded to Mac OS 10.6, Flash may no longer work in Firefox 4 Beta 7 or above, even though you are using the latest version of Flash. This is caused by a Flash bug. As a workaround, you can run Firefox in 32-bit mode, as follows:

  1. From the menu bar, select Firefox and then select Quit Firefox
  2. Open the Applications folder in Finder and locate the Firefox application icon.
  3. Hold down the control key while you click the Firefox icon and select Get Info from the list of menu items.
  4. In the "Firefox Info" window, click the box in front of "Open in 32-bit mode" so that it is checked.
  5. Close the "Firefox Info" window and then restart Firefox 4.
