Right click Flash content. Select Global Settings.

Under the Storage tab you can set storage settings by site.

Whenever Flash Player is accessed to play an embedded video I keep getting a 'message box' called Adobe Flash Player Settings which covers the centre of the video. It mentions something about embedded-ssl.wistia.co wants to store information on my computer, with 2 buttons, Allow or Deny. No amount of clicking on any of the buttons will make it disappear, hence I cannot watch the video properly.

A remedy was allegedly found on the net where one goes to Control Panel>Flash Player, and right click to access settings. However, when I right click on it, I get the message: "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item." That made me quite angry.....I'm the administrator and it's my flippin' computer...yet I'm not allowed access!!!

I tried un-installing and re-installing Flash, directly from Adobe, but still get the Wistia problem. Any advice to eliminate this persistent annoyance.

The advice above from Mike M produced the same "Windows cannot access the specified device, path or file...... message.

Why do I need Flash??????

I was trying to watch a video just a few minutes ago and got that same dialogue box...right in the middle of the video screen and no amount of clicking would remove it. I decided to right click on the video and it gave me a menu box that offered the option of telling it to switch to HTML5. I clicked on that, and that annoying dialogue box went away. Of course the video started over again at the beginning too. Not sure if this helps or not. BTW...my O/S is Windows 7.

That's our anti-clickjacking protection kicking in. This typically happens when the dialog comes up, but pixels around it are moving in the background (like a video playing behind it), or occasionally at specific resolutions and pixel densities (that's a whack-a-mole game, we fix it in one spot and it shows up in another).

These dialogs are encountered typically because you've changed the privacy settings in Flash, which is cool, but you get some side-effects.

There are a couple ways to get around this stuff.

The best way is to use the private browsing/incognito mode in your browser. You let the content save whatever it wants, so it never prompts you. What the content doesn't know, is that everything being saved is going into a temporary directory, which gets deleted when you exit the private browsing session. This is the best way to accomplish privacy hygiene because it defeats all of the HTML5 vectors for tracking (of which there are many) in addition to the Local Shared Object store in Flash. It also instructs Flash to provide less information that can be abused for server-side fingerprinting (like a *very* reduced list of available fonts).

Alternately, if you clear your browser cookies, Flash gets the event and deletes the Local Shared Objects as well. You can also control the local shared object preferences by going to Control Panel > Flash Player. If you go to Storage > Local Storage by Site, you can set an always deny preference, but the side-effect, since the content's request to store data fails, is that the content provider may choose not show you the content. For instance, if blocking the storage of a token impacts their ability to get paid by the advertiser who is covering the costs of producing and delivering that content to you, they may not choose to service your requests.

Hope that helps.
