hmm, that's right, the security spans across all instances of FP.
However, I tried again and failed again. (no other tab, no other flash running)

full message (loosely translated to English)

SecurityError: Error #2122: sandbox violation: SoundMixer.computeSpectrum: [link] cannot access [link] A policy file is required, the flag checkPolicyFile has not been set when the file got loaded
at flash.media::SoundMixer$/computeSpectrum()

As you can see, it is about music.

Ou, thanks. Yeah seems there is an error.
Ok then I need more info from you. What OS you use, browser? If FireFox, do you have FireBug, can you check if it tries to access this policy file: [link]

FF 4.0.1
FP 10,2,159,1
Win 7

I'm not a web developer guy so I don't have firebug, but I always wanted to install it one day as it is a handy tool.

I installed it now, but I couldn't find out how to monitor the networking yet.
The problem is, when the error pops up, FF completely freezes for about 10 seconds, then the plugin is crashed and FF comes back to live.

quite odd

Okay, you need to open it, there is Net tab. Click it, then click on triangle on that tab button that appears when you choose it and select "enable".
Now refresh the page, you should see all request done by page start to show up there.
Select HTML sub tab to filter out images and stuff. Only html/xml stuff should be left. Somewhere towards the end there should be crossdomain.xml, when you roll mouse over it it shows link from where it was requested.

For me at the end it does request crossdomain from amazon server that allows it to access sound data for spectrum. Hmm, though sometimes it seems songs starts playing before it loads so that's probably what causes an error... Will need to fix it. Probably this is the real problem.

About Firefox, since 3.6 version they ruined Flash sadly :( They tried to put it to separate thread you can see in processes called plugin-container. Good idea but their implementation sucks... Flash become unstable and completely unusable if you have developers version. I now use Chrome for extensive development for that reason :(
Otherwise FF still, many extensions just rule :D

Thank you for the intro, I finally had the time to try it again.

Ok, here's what happens:
- the flash shows up and starts playing music.
- It tries to request the crossdomain.xml
- the error pops up, music keeps playing, FF freezes.
- FF comes to life again: the timeline of the crossdomain xml request shows up
- answer of the request is empty
- in the xml tab: (again: translated to English)

- it tries to load the xml file several times.

I once wrote an email to a guy who had an error on his website. He replied and told me it was his twitter reader who had trouble with the xml that it was loading, there was some character in front of the first xml tag, which cause the trouble.
I guess this is the same with your case.
notice the "^" at the end of the message.

oh dear, yes, FF sucks with Flash.
I had the Incubator for a while, but it was a nightmare.
Everything threw errors.

I'm not sure about chrome with all the bad news about google.
But well, I have an android phone, so they probably already know everything about me =D

Hmm, so there is some error loading crossdomain for you? Curious... Works fine for me.

Hmm what kind of news on Google? That they collect and use a lot of info?
Schweinskopfsuelze's avatar
Yes, their greed for personal data is what I was talking about.
But even apple was too stupid to hide theirs (not as if I expected anything else), so I can savely assume that every company will collect data.

However, it has always been a common "fact" that google collects.
Apple always tried to brainwash everybody to think they are the good guys.

Choosing google seems to be the best of the bad.

Well large data is considered to be one of biggest assets today, main fights for that now are Google and Facebook, others are just forerunners it seems, at least for now. Apple failed with their cloud projects so far, Microsoft is just weird :)

As for choices, my align with Google, but I am a weirdo and honestly am curious in how being public and sharing information would come bite me :)
I mean sharing my interests so that they spam me with stuff of my interests? How bad that can be?
Also as far as I can say most of them collect info in anonymous way, they can't really connect it back to me.
Even if we take that example of iPhone collecting that data, only true problem is that it was easy to stole it and also that it was done in secret. Basically I very very hate Apple for their secretive ways. Not acknowledging problems, hiding stuff etc... I have completely no idea in why it is a good strategy... I rather find it to be dangerous.

As for google, I like what they do and what they strive for, for information and internet economy, its way better for me then locked up app system of Apple for example, or walled garden of Facebook... Though Google is a walled garden in a way too, just a lot more open one :) Or so it seems to me.
