Deleting cookies from computer.
Win7 SPi Firefox 22
I have turned off the cookies in Firefox, but when I run CCleaner the same set always appears on its result screen. Where are the cookies stored in Windows Explorer so that I check it out? The cookies always appear only when I start up Firefox. Peter |

My copy is several years old. http://www.sqlite.org/download.html HTH, Paul Thanks, I did this and used a Hex editor to delete the contents. It didn't work though. Arrgh! No, that's not necessary. Delete the file if you're unhappy with it. I don't know where the garbage is coming from in the file. (It's possible when you clear cookies, the file size is never reduced, and only certain sectors are completely rewritten.) The sqlite .dump command shows what is "real" in the file. The parts that don't matter to sqlite, I don't know if they were already on that disk sector, or whether an uninitialized buffer in the sqlite driver is doing that. If you wanted to "cleanse" the file, you could try re-creating the file, using the output of the .dump. As far as I know, the stuff in the .dump output, should be the same stuff needed to re-create the file. I've never had to do that before, so I don't know the recipe right off hand. It occurs to me, that maybe what I need, is VACUUM command. Vacuum is not to be used carelessly. I've seen claims you need to re-index or something, before you're done. So it isn't perfectly harmless, when there are multiple database files. http://www.sqlite.org/lang_vacuum.html It would be something along the lines of sqlite3 cookies.sqlite VACUUM; As seen here... http://www.reddit.com/r/linux/commen...ases_for_f_in/ You play with the databases, only when Firefox is not running. You'd check Task Manager to make sure. (Because Firefox is not dead, even if the GUI goes away. Sometimes it is still running, which is why you check Task Manager before VACUUMing. And until you can prove what you're doing has no side effects, keep backups of any important files. For example, if you're playing with vacuuming places.sqlite, you'd keep a backup copy handy just in case. OK, when I VACUUM my cookies.sqlite, it becomes 2048 bytes, and only the important stuff remains (no more garbage). If I do a dump again, I get the expected stuff for an "empty cookies". So it's not damaged (because we expect it to be virtually empty, and there is nothing to index here). PRAGMA foreign_keys=OFF; BEGIN TRANSACTION; CREATE TABLE moz_cookies (id INTEGER PRIMARY KEY, name TEXT, value TEXT, host TEXT, path TEXT,expiry INTEGER, lastAccessed INTEGER, isSecure INTEGER, isHttpOnly INTEGER); COMMIT; It might be a different situation, if there were actual cookies in there, and VACUUMing created an indexing problem. I don't know anything about databases, and this is just something I read when researching what happens if you vacuum places.sqlite or equivalent. In the case of places.sqlite, you're trying to preserve that one most of the time, so it's important not to damage it. ******* Firefox Private browsing mode... http://forum.piriform.com/index.php?showtopic=22704 Near the bottom of that page, it mentions that "sessionstore.js" can contain cookies. It's possible if you kill Firefox with Task Manager, cookies could be left in there. And conversely, the cookies.sqlite gets updated when Firefox exits. In a test here, sessionstore.js exists if you "kill" Firefox from Task Manager. Whereas if you shut down Firefox normally, there is no need to keep track of the session, and sessionstore.js is deleted. So it's just a way of allowing you to recover a session if Firefox exits abnormally. So I don't see that as being an issue, unless you go around "hammering" Firefox a lot just for fun. When I looked in my sessionstore, I didn't see a cookie, but plenty of URLs were in there anyway. So it does keep some information. But on a normal termination of Firefox, that file is gone. Paul |

Not a Windows 7 issue. A Firefox issue. The Firefox newsgroup is over at: mozilla.support.firefox (on Mozilla's NNTP server: news.mozilla.org) You sure you didn't install some extensions that themselves create cookies. It's been awhile but I remember some users noting some extension create their own cookies. You would have to uninstall those extensions or always run Firefox in its safe mode. For example, the TabMix extension for Firefox stores its own session information in cookies that it creates. You need to review what extensions you installed and educate yourself on their behavior(s). Another source for saving cookies is Firefox's own session manager. You would have to disable the built-in session restore but then you won't have crash recovery. For these extensions or Firefox, just where are they supposed to store the session data when Firefox is not running or when it crashes? If that info weren't in cookies then it would just be in some other handy file that survives between Firefox sessions. |

Few people know about Macromedia flash cookies. They are really insidious; tracking our streamed videos. I stopped using Flash because of the hidden persistent cookies, and because a lot of websites are using HTML5 Video, but now it looks like an even worse tracking cookie is available. The Forever Cookie. This is from an article I was reading that some people might find interesting: From Wikipedia: An Evercookie is not merely difficult to delete. It actively “resists” deletion by copying itself in different forms on the user’s machine and resurrecting itself if it notices that some of the copies are missing or expired. Specifically, when creating a new cookie, Evercookie uses the following storage mechanisms when available: Standard HTTP cookies Local Shared Objects (Flash cookies) Silverlight Isolated Storage Storing cookies in RGB values of auto-generated, force-cached PNGs using HTML5 Canvas tag to read pixels (cookies) back out Storing cookies in Web history Storing cookies in HTTP ETags Storing cookies in Web cache window.name caching Internet Explorer userData storage HTML5 Session Storage HTML5 Local Storage HTML5 Global Storage HTML5 Database Storage via SQLite Hold on – there’s mo The developer is looking to add the following features: Caching in HTTP Authentication Using Java to produce a unique key based on NIC information.
