To quote the article: "When a consumer goes to a PIE-enabled website, the visitor's browser is tagged with a Flash object that contains a unique identification similar to the text found in a traditional cookie. In this way, PIE acts as a cookie backup, and can also restore the original cookie when the consumer revisits the site." Please consider blocking these kinds of "cookies" too. I'm sure that there must be a duplicate bugzilla bug in here somewhere but I can't find it. Reproducible: Always Steps to Reproduce:
Update: there is an extension for Firefox that does this: <http://www.yardley.ca/objection/> "What is 'objection'? objection is an extension for Firefox that adds deletion of Local Shared Objects to the Option > Privacy panel." It would be nice for this feature to be integrated into firefox.
that page made it clear that this is handled entirely in the plugin. thus, it is completely out of the scope of the networking library. -> ffox frontend (Hm... comment 0 says you are using mozilla, not firefox?)
Christian Biesinger (:bi) wrote: > (Hm... comment 0 says you are using mozilla, not firefox?) I'm from the Flashblock team so I use both for testing. I opened this bug because someone in the flashblock mailing list asked us to block flash cookies as well. I thought that this was more appropriate as part of firefox/seamonkey instead of an extension - then several minutes later I find the "objection" extension while looking for something else. Grrr. The author of objection totally replaces PrivacyPanel.clearAll() instead of handing off to the original after processing the LSOs.

I don't see a dupe of this bug, marking as new.
There is no patch. And even if there were, it would have i18n impact. I think it's too late in this cycle to block.

Not blocking, far too late for changes of this type.
Surely there are other plugins that store private data. Shouldn't we simply have a "Plug-in data" checkbox in the Clear Private Data... window? Why clear just cookies and leave other private data on disk?
Is there a universal "clear plugin private data" API or does each plugin do things differently? If the latter I don't see how it would be practical to build in awareness of any and all plugin data handling not just for currently existing plugins but for any hypothetical future plugins from some obscure developer in Upper Moldavia.
There doesn't have to be a consistent API for Firefox to do its best for the common ones, Flash, Java, QuickTime, WMP, Acrobat and a few others.
(In reply to comment 15) > There doesn't have to be a consistent API for Firefox to do its best for the > common ones, Flash, Java, QuickTime, WMP, Acrobat and a few others. In that case I suggest that having a "Plug-in data" checkbox in the Clear Private Data dialog would give a wrong impression, not to mention a false sense of security to the average mom'n'pop user who doesn't realise that this only clears data from popular plugins. Unless of course you change it to a "Some Plug-in data" checkbox.
Philip, no more misleading than our current "clear cookies" or "clear offline website data" (and probably others) neither of which are cleared in certain plugin cases. You're making perfect the enemy of good here. We can probably never get everything and we can't be 100% accurate in our labeling without making the dialog unusable.
> You're making perfect the enemy of good here. Asa, normally I'd agree with you (i.e get something working first, worry about perfection later), but one of our "selling points" is that Firefox does security better than that other browser so I want to be more cautious when it comes to this type of issue. But I'll defer to the security and UI people who know more about these sort of things.
Hi just wanted to let y'all know, the objection plugin is not compatible with 3.5. Thus the workaround no longer works.

Hi, we (Adobe) are planning on supporting private browsing in Firefox and other browsers in a forthcoming Flash Player release. additionally, we would welcome an NPAPI addition that would be called when a user wants to clear their private data. this is in our future plans also, but would likely happen a lot faster if this was implemented by Mozilla, rather than us having to write the patch for it ourselves.
also PLEASE do not try to clear LSO's in the browser code - imo this is something that should be handled by plugins themselves via an NPAPI addition.
Ian Does Adobe have somewhere where interested people can contribute to discussion on the implementation? There are some, in my opinion, very complex issues that Adobe will have to overcome. I have been looking at implementing Private Browsing mode support into Objection and the only solutions I came up with could create big problems for the user.
Linux users or extension developers may wish to know that the popular swfdec plugin stores site information in the file ~/.config/swfdec-mozilla (or similar).
Private browsing in Flash Player 10.1 http://www.adobe.com/devnet/flashplayer/articles/privacy_mode_fp10.1.html Adobe Flash Now Supports InPrivate Browsing http://blogs.msdn.com/ie/archive/2010/02/11/adobe-flash-now-supports-inprivate-browsing.aspx
Ian - With Private Browsing, it looks like Adobe has decided to ask the browser if it is in Private Browsing and choose its mode based on that, correct? Also, I don't see anything in https://bugs.adobe.com for allowing the browser to tell Flash what to clear. All - If this bug was specifically for Firefox Private Browsing, then I'd say it is resolved and a separate bug is needed for regular browsing.
Chrome now allows the user to clear Flash cookies. Their idea might be worth checking out: http://www.imasuper.com/640/technology/chrome-adds-links-to-clear-adobe-cookies/ Their solution is not complete, but at least a first step towards some control.

I changed component from Private Browsing to Security because there is no Private Browsing component in 3.0.19. I changed to Security, as then websites can see what Flash cookies are there (what websites you have visited.)
mconnor has already minused blocking-firefox3-. Don't renominate bugs for a branch that have already been denied by drivers. This is a privacy issue not a security issue. Please don't confuse the two concepts. There are no patches here. Nobody is working on this bug - See the Assigned to field. It is useless nominating bugs such as this without a clear plan, without clear goals, without any working patches. If you want to discuss this issue please do it in the mozilla forums e.g. newsgroup mozilla.dev.apps.firefox rf the associated mailing list.
Presumably this missed 4 but I see no way to nominate for 4.next so giving blocking2.0? a shot. (btw, implemented in Chrome here http://codereview.chromium.org/5579002/ )
Looks like they did it by making modifications to the version of Flash that they ship, which we can't really do at the moment. We can't block 2.0 on this at this point.
The NPP_ClearSiteData API is being finalized right now, and given Adobe's interest they'll likely implement it fairly quickly. We should get started on the Firefox code to aid in their testing, with an eye to roll this out in a point release.
Changing summary to better describe what we're actually going to do here. (If we want a separate bug on clearing plugin data when you clear cookies, we should file one, but I don't have a strong opinion right now. I think this will be better solved with the new site preferences/history UI in the works.)
I suspect that this bug will become a meta, since it's about "plugin data" now and bug 618461 is just about Adobe Flash. That's probably OK. I'm going to open a new bug for the UI hookup for Flash.
