Hello Lovette,
When you ask:
> . Is there a way to toggle flash player on and off?
Do you mean is there a way to manipulate the player controls if they are 
embedded in Adobe flash that is not accessible (and there is not an accessible 
HTML5 of the web page)?  The only cases I can think of where you are using 
VoiceOver for this involve figuring out where the controls are by using Mouse 
Keys to move the cursor over the play/pause button and then clicking your 
mouse.  You'd have to set up VoiceOver so that it announces what is under the 
mouse when you move over it (in VoiceOver Utility > Verbosity > Announcements 
tab checkbox for "Speak text under mouse after delay") in order to locate the 
controls this way.

Or are you referring to a way to disable flash from playing in Safari via a 
Safari extension or plug-in? This was done with the Click-To extension or the 
Click-to-Flash plugin.  Flash installs as a plug-in for your browser, so you 
can disable it via the security tab of your Preferences pane. Command-comma to 
bring up preferences in Safari, then navigate to the security tab and uncheck 
the box for "Enable plug-ins".  For some Flash content, such as YouTube videos, 
when Flash is not available and there is an accessible HTML5 version of the 
page contents, you'll be taken to that page, and be able to use the player 
controls with VoiceOver.  But not all pages with Flash content have HTML5 
versions.

Because of security issues with Adobe Flash, the recent Safari updates started 
blocking out-of-date flash plug-ins.  Also, new Macs don't come with Flash 
installed on the system by default any more.  You have to download and install 
it from Adobe if you want it to run on your computer, and I think that's been 
true for nearly a year now.  It then shows up as an additional item named 
"Flash Player" in your System Preferences, and can be set to automatically 
check for updates (the default), or you can navigate to the Advanced tab and 
then manually check for updates.

I just read that the latest version of Safari 6 (just released) may also give 
messages blocking the flash plug-in.  That's part of Apple's recent move to 
block outdated flash plugins as a security measure, and was also a feature of 
the last Safari 5 update.  If you have a new Mac, and previously had flash 
installed, you may have to delete a file named "Flash Player.plugin" (without 
quotes) and with an old modification date from your system's library folder for 
"Internet Plug-Ins". If you have an older mac, you may have a sub-folder for 
"Disabled Plug-Ins" where you want to delete all references to Flash or 
Shockwave. You can navigate to this Folder with the Command-Shift-G "go to 
folder" shortcut, and type or paste into the text field:
/Library/Internet Plug-Ins
and press return.  Note there is a slash before and after "Library" to indicate 
it is a top level system folder -- not your user account's Library folder -- 
the slash after indicates that "Internet Plug-Ins" is a subfolder under 
"/Library".

If you have questions about playing Flash on your Mac, please write back with 
more details about what you want to know, so list members can address these 
topics in their replies.

Cheers,

Esther
