Outstanding! Would you please make one for Opera 12. 10+ (which has no cookie killers/cleaners) Rated 5 out of 5 stars

I have tried all of the cookie add-ons available in Chrome, Firefox, IE, and Opera (but, as I noted, there are none for Opera ver. 12.17)

Why am I using the latest iteration of Opera version 12.1x?


And I define the IE acronym as "Intrusive Environment", and not "Internet Explorer."

Firefox is my main browser EXCEPT for printing and saving web pages - because, beginning with v30, it will not work with my XP SP3 OS. Yes, I know it's very old school but I am upgrading my computer this week, rather than having to buy a genuine Microsoft installation disk of Win 7 (not Win 8) and a 2nd hard drive OR hopping on eBay where sellers get away with packaging a "Win 7 installation disk" along with a peripheral or a piece of hardware like an inexpensive interface card or small amount of RAM, or putting it on a new HD and passing along the authentication key (with or without the reinstallation disk).

But, since there are a lot of people still using XP and Vista - despite the caveat of being "a hacker's paradise" now that MS no longer supports them, it would have been nice if Firefox 30 were fully backwards compatible. IIRC, v29 still was, but like a thief in the night, Mozilla updated it in the background w/o informing users about its "little compatibility issue."

Anyway, on to a review of Firefox 30's SDC add-on:

The fact that you can UNDELETE cookies should have answered a lot of people's questions about losing cookies that they should have kept. Since every cookie cleaner worth its salt has, at a minimum, a WhiteList of what you do NOT want deleted, it falls on the user, and not the developer, to manually enter those sites that require cookies to be stored. Additionally, if you don't like having to re-log into your favorite sites, and you are the only person using the computer, then those cookies should be protected as well.

Since I do not delete cookies known as LSOs, aka persistent storage or Local Storage, from secure server websites (SSL, HTTPS) without knowing what they are, where they came from, and if I must keep them available, I choose to handle them on a case-by-case basis.

The LSO's to watch out for are called "ever-cookies" or "zombie cookies" that you think you killed but return from the dead.

The main category of LSO's that you should inspect are Flash cookies. Most are required for showing embedded video and animation (e.g., Macromedia ShockWave and Adobe Flash Player). Some may be safely removed without affecting a web page or displaying a video (if it uses HTML5 instead of Flash) but YouTube and Vimeo are two sites that rely heavily on Flash and should be put on your Whitelist. (It would be nice to have a BlackList as well).

Since Flash is also the carrier of choice for viral infections (along with PDF), and also one of the primary reasons for random updates of browsers that use Flash and PDF plug-ins, everyone should be paying attention to their LSO's. There is a "default" Flash LSO that gets updated by every site that requires Flash. You may want to delete that after filling in your WhiteList with the sites you frequently visit. Then, when you revisit those sites, the default Flash LSO will only contain their entries and be protected if you do a global deletion of Local Storage via SDC.

You can have the best of both worlds by creating a separate browser profile that you can choose when starting Firefox. Each of your profiles can have a different set of instructions for handling cookies and local storage.

By pressing the START key, then RUN, and typing into the box the following:

firefox.exe -p

Press ENTER and you'll be taken to the "Select a profile" dialog (that is normally kept hidden with your "default profile" highlighted) and from there, create a New Profile with a new name, and then unchecking the "Use this profile when starting" box in the dialog so that you can manually choose which profile to load when your browser starts.

Here are the features of SDC I like:

OPTIONS SECTION (Tools, then Add-ons)

* Grace period (for cookies that sneak in after your webpage has been loaded and past your normal cookie filtering procedures).
* Turning off Notifications (that are really annoying BUT I advise newbies to leave it on for a few sessions just to see the avalanche of original and 3rd party cookies that assault your session. The evidence of it is getting a Notification balloon that's 1/4 the size of your browser window!)
* Include Local Storage (leaving the choice of Keep/Kill in your hands)
* Undelete Cookies
* Allow 3rd party cookies (although it can be turned off from within Firefox, SDC is the only way to undelete them if accepted).


* being able to temporarily suspend operation and resume operation
* choosing when and where to remove cookies (e.q., After browser closes or after Tab closes, or Never)
* undelete cookies
* the icon color and animation.

I like them but other people don't - maybe they have a low tolerance for distractions or short-attention spans. I don't notice it because I'm too focused on what I'm doing. I also prefer knowing that an add-on is working and in what state it currently is.

Good grief, it's a tiny red dot in the upper right-hand corner of the window that pulsates when operating. (It's not like my antivirus icons in the taskbar that are blinking, winking, or revolving. My resident malware shields, though, stay still (Spybot Search and Destroy and MalwareBytes Exploit).



There are very few add-ons that get 5 stars let alone deserve them. This is one of them when you compare it against its competition (I have not seen anything else do what SDC can, so your experience may vary, as they say).

Like I said, the only negative is not having it available for the NON-CHROMIUM BASED generation of Opera browsers. They took a really different approach to browsing -very unlike the "gravy-train" browsers that were nothing more than a fancy overlay on top of an old version of IE, or worse, a clumsy rebranding of Chrome.

My love for Google, notwithstanding, now that they shoved YouTube and every other program they run under Google+ because they could not compete as a social media site with Facebook, LinkedIn, Tumblr, and Pinterest running "circles" around them. ;-)

Perfect. This is exactly like it should work in every browser!
Only accepted/friendly cookies may remain, rest is gone..

Brillian addon Rated 5 out of 5 stars

I love the way it solves the cookies issues.

I'd like to use this space to make a comment. I also block all my cookies by default (as the question in the Q&A). I tried the suggested answer and it did work but for some reason it works as the "yellow" setting some times and others as the "red" one (I would like it to work always as "red").

Could it be based on the origin of the cookie? meaning, I have domain.com white-listed to accept session cookies but I got a cookie from sub.domain.com, then it acted as "yellow". With another site, if the cookie was directly from domain.com it acted as "red".

Greetings and thank you!

Works as advertised. A minor annoyance is the button's animation when notification are disabled which is rather pointless, just like the notifications, and distracting.
An option to disable the animation would be useful, like for any pointless eye candy.

Rated 5 out of 5 stars

This is an excellent add-on! Does what it says. I only miss one feature...

I would like be able to whitelist single cookies, so as to avoid having to close all those annoying one-time messages in Wikipedia, Google, YouTube etc... that just inform me about their cookie policy or automatic setting of my language.

I'm on android (4.4.2) and I'd like the menu entries to be in thier own folder to save room & scrolling.

missing SDC icon win7 FF30.0 + the addon bar (restored) v3.2 Rated 4 out of 5 stars

Upgraded to FF v30.0 now SDC seems to be working cause i see the pop-up notice but the config icon is missing so i cant select per website a cookie setting unless i edit the whitelist manually.. this really sucks. don't know if "the addon bar (restored)" has anything to do with it, but i had to install that to get another addon to display it's icons... soooo it sounds involved ! in some way.

Update: me so stoopid.. it turns out the icon was available when editing ( customize) the menu items... i didn't recognize the grayed out version so didn't notice till i mouse-overed and the text title showed .. got if all setup now :)
displayed as a text title while editing http://prntscr.com/3ta3t7
It was there all along... just didnt see it...

I love this program. It is wonderful, and I think it is the best thing I ever did to protect my privacy. People complain about seeing all the messages, but I like it (you can disable this), because I know it is working.

How to delete the google PREF cookie Rated 5 out of 5 stars

I recently upgraded from Firefox 29.0.1 to 30.0 and opened Firefox / Preferences to confirm the settings.

I accidentally placed a check mark before / Security / Block reported attack sites.

Additionally, I accidentally placed a checkmark before Block reported web forgeries.

I removed both checkmarks.

I knew from previous experience that whenever those two / Security settings have a checkmark, the google PREF cookie automatically installs in Firefox.

Before I upgraded to FF 30.0, if I accidentally entered checkmarks before the aforementioned / Security options, I would uncheck the aforementioned / Security options, would remove the google PREF cookie from the list in / Privacy / Show Cookies, and confirm that google.com Block appeared in the list in / Privacy / Exceptions.

However, after I upgraded to FF 30.0, the preceding method failed to remove the google PREF cookie because each time I removed the google PREF cookie, it instantly reinstalled in Firefox.

However, I discovered the following simple method that successfully removed the google PREF cookie and permanently blocked the google PREF cookie from installing in Firefox:

(1) Open Firefox / Preferences / Content / Languages / Choose to open the list of languages.

(2) Select each language in the list. Remove each language from the list including English/United States [en-us]. Remove them all. Click OK

(3) Open Firefox / Preferences / Security. Uncheck Block reported attack sites. Uncheck Block reported web forgeries.

(4) Open Firefox / Preferences / Privacy / Exceptions to open the Exceptions – Cookies list. Enter google.com and click Block. Close the Exceptions – Cookies window.

(5) Open Firefox / Preferences / Privacy / Show Cookies to open the Cookies list. Remove all google.com cookies including the google PREF cookie. Close the Cookies list window.

(6) No google.com cookies or google PREF cookie will install in your browser again.

(7) You can return to Firefox / Preferences / Content / Languages / Choose / Select a language to add... and add as many languages as you want to add to the language list, but now the google PREF cookie will not install because you previously unchecked the / Security options as in the preceding paragraph (3) and you blocked google.com cookies as in the preceding paragraph (4).

I think Self-Destructing Cookies is an indispensable add-on. It is a tremendously effective add-on. I would not want to be without SDC.

good addon, except... Rated 3 out of 5 stars

it does not delete the google PREF cookie. this is not good. is there a specific reason or is it a bug as i suspect?

Thanks Rated 5 out of 5 stars

I just noticed this is now deprecated. That's a real pity, it's been good having it. I had a problem with it popping up notifications in a loop - possibly conflict with another addon, but I haven't changed anything (except another one updated, but I disabled that and the problem persists), so I'm thinking it may be becoming unstable without support and I'll have to find something else to kick those cookies into touch. Thanks very much Ove, and all the best.

Very useful, but... Rated 4 out of 5 stars

Adding export and import of whitelisted sites would be awesome(or even online sync). When you have manually whitelist hundreds of websites after FF or OS reinstallation, it is a real PITA ;)

perfect privacy controller

very useful for protecting your online accounts Rated 5 out of 5 stars

Self-Destructing Cookies prevents hackers from taking over your online accounts if they get access to your computer, and all you have to do is close the tab of the website you're visiting. (it also enables logging out without needing to hunt for the logout button.) cookie deletion is necessary because Firefox stores cookies unencrypted, making it possible for an attacker with access to your computer to log into your e-mail, and from there, reset most of your other online account passwords.

Awesome little addon Rated 5 out of 5 stars

Never had any problems with it, and I love seeing no cookies leftover. Great little security trick!

EXCELLENT!!! Rated 5 out of 5 stars

excellent! i got tired of deleting cookies one-by-one, this does the job, but i can whitelist the hadful i want to stay.

note: i'm using FF28/FF24ESR, so i'm not having the CPU/memory problems others are having (say no to australis!)

Using this plugin is the simplest way I have found of killing all cookies except the small number that I want to be persisted.

Excellent stuff.

Nice idea - but heavy memory and CPU usage on startup Rated 3 out of 5 stars

Using Firefox 29.0.1 currently.
When I start Firefox it has 20+ windows and roughly 1000 tabs. During startup with this plugin enabled, the CPU usage by the firefox process is 100% constantly and the memory usage grows to 6+GB, before it drops down to 2GB. The whole process takes several minutes (!!!) before even the normal Firefox initial loading of tabs resumes. I do think needing 4+GB for this plugin to get started to get going (albeit on a heavy session) is a "bit much"... Starting with the plugin disabled just creeps the memory usage to 2GB for the same session, and is done in a few seconds.
The idea is good, but the implementation is still a bit early for heavy web users - although we are the ones really craving for such features.

Rated 3 out of 5 stars

Seems to cause significant slowdown and RAM usage for FF29 startup with a hundreds of open tabs.
FF28 was OK with it.

Excellent !! Rated 5 out of 5 stars

Great addon ! Setting "extensions.jid0-9XfBwUWnvPx4wWsfBWMCm4Jj69E@jetpack.defaultBlock" is great !!! Allows "yellow" cookies to be destroyed after desired amount of time (default 10s).
