With all those webvideo sites around nowadays it is kinda hard to sound 
convincing when stating "I don't use flash" :)

For the missing deterioration: That's one of the reasons I still follow this 
list


cheers,

I have to say, I'm surprised that this discussion hasn't deteriorated to:

Reply 1: I don't use flash
Reply 2: I don't use gui browsing, it's text based browsing for me
Reply 3: etc...
a-la http://xkcd.com/378/ .

You can configure Flash directly by visiting

(Website Privacy Settings / Website Storage Settings)

And while you're there, there are lots of other settings you may want to 
adjust...

Subject: [funsec] Firefox' privacy mode not so private

Heya
It seems this was some kind of a 'known secret', but firefox' privacy mode 
isn't private. Apparently, websites[1] can use flash to store 
'Local-Shared-Objects' (LSOs, see 
http://en.wikipedia.org/wiki/Local_Shared_Object ), which are basically 
cookies. Firefox' regular capabilities of 'clear all private data' and 'privacy 
mode', which supposedly don't leave any record of your browsing history, don't 
erase these files.

Simplest solution: erase the files.
Other solutions: install BetterPrivacy (disclaimer: I didn't use it enough to 
vouch for it), uninstall flash (and delete the files), install a flash-blocker, 
etc.

I've also written a short blog post on the subject, you can also leave your 
comments there:

Cheers,
Imri

[1] websites include at least google and youtube, various cdns (which may be 
used by multiple websites), etc.
