Not working. Rated 3 out of 5 stars

Used to be great, could be safe with quick and secure deletion. Now? Not so much as it does not actually delete the needed files no matter what option you use. Once this is hopefully updated to fix this glitch I will be using it again every day, however until then I shall leave it turned off. 5 stars when working, 1 star when broken so go for 3 star atm. Please fix this wonderful little addon.

It doesn't "sanitize" anything anymore since 44.0.2 FF version Rated 1 out of 5 stars

I'm about to uninstall it as well as "Ask for sanitize". I already installed "Empty Cache Button". Of course, it doesn't use US DOD 3 passes tool, but for the moment Secure Sanitize not only stopped to use DOD 3 passes : it doesn't erase ANYTHING ANYMORE, which is worse ! Secure Sanitizer desingers have from now on my mail address. As soon as Secure Sanitizer again "sanitizes" anything again, let it know to anybody. Meanwhile, it will be "Empty cache button", which is better than nothing.

Doesn't work with the last update (Firefox 32 and above). Issues with cache2.

Cache cleaning in Firefox 32 doesn't work Rated 2 out of 5 stars

Cache cleaning doesn't work in Firefox 32 onwards because now the Cache is in Cache2 folder. Please update this extension so that we can securely wipe the cache.

All tracks fully deleted except HTML5 storages Rated 5 out of 5 stars

Secure Sanitizer 0.5.0 is a great add-on, but I am expecting a new version which also delete HTML5 storages. This add-on works fine, deleting all surfing tracks and all login ID/passwords to bank account.I have set on the option "US DoD 5220 3 steps" to get the higher cleaning.However the HTML5 storages are not deleted at all and I had to install the other add-on "Foundstone HTML5 Local Storage Explorer" just to do a complentary cleaning of my tracks.

Using Cache to remove data. Rated 5 out of 5 stars

Is information from Pagefile system removed when Cache is cleared?

No ability to automatically sanitize cache on shutdown Rated 3 out of 5 stars

Shoot, I've been using this for months without even realizing it wasn't doing anything! FF11 and later disables the cache when you elect to automatically clear on shutdown. And "AskForSanitize" forces me to choose every time what I want cleaned.

I just want a program that will automatically wipe the cache every time FF is shut down, without me having to do anything. But I do want the cache enabled! Why did Mozilla have to disable the cache completely? Makes no sense.

Maybe "AskForSanitize" can have an option that won't need user input for cache deletion.

Great Idea! Rated 5 out of 5 stars

Great Idea! - A must feature!

Two negligible non important issues :
1] As the honored developer Fabio Santagostino mentioned in the bottom,
the latest FireFox version (v11.0) disables disk cache when 'Clear private data at shutdown' is enabled.
So you will see the progress bar remains on 0% on exit.
2] When using with Biscuit V2.1.4 add-on
( )
you won't see the radio options which let you select the wipe type on the "clear recent history" window (activated with ctrl+shift+del or from the Tools menu).
of course you can see the options on the 'Clear private data at shutdown' window.

But those issues are really negligible and non important,
So do not hesitate it's a great feature!
Thank you Fabio!!

Secure Sanitizer (v 0.5.0+) trace all errors in "Web Developer > Error Console". Do you see any error when executing SS ?

Moreover FF 11.0 has a new feature (bug?) that disables disk cache when 'Clear private data at shutdown' is enabled (see

Hi Fabio,
sorry for the delay. I made a screen shot of all my add-ons, you can find it (within the next 28 days) here:
Hope that helps!
And thanks once again!

Ok, thank you. I'll take a look to your (long ;-) ) list and try to test SS with these addons .
In the meantime I'm releasing version 0.5.0 with a better use of random data and error reporting in Error Console. Maybe this can help solve this issue.

It doesn't wipe data Rated 2 out of 5 stars

I tested on several portable FF versions (old and new, and without ANY add-ons except for SS and Ask For Sanitize), with several SS versions (old and new), and I ALWAYS could restore, with a simple file recovery program ("Restoration"), after the alleged "wiping" took place, the fully intact images I had downloaded for testing purposes.

I seem to remember that formerly SOME (not all) files were no more usable after a wiping operation. The file recovery program formerly still displayed the file names (in the FF cache format), their size and date, but the content of the files had been replaced with question marks when I opened them in a text editor, so most likely some real wiping had taken place. Not sure why I can't reproduce that anymore. I've removed SS for now. But I'll try any future versions.

BTW, the bug I mentioned with regard to SS's wiping choice no more appearing in the "Clear History" dialog is related to the "Biscuit" add-on (manages permanent cookies). After disabling that add-on, the options reappeared.

Two stars (one is for your effort to keep dealing with the problem). ;-)

This review is for a previous version of the add-on (  This user has 3 previous reviews of this add-on.

As you noticed SS wipes only the content of cache files:
+) file names in cache format (i.e. AB345GF, etc.) don't hold sensitive information;
+) modified date/time is changed to the date/time of the wiping operation;
+) file size is kept unchanged, but I can plan to change it also to reduce the risk to be detected.

Anyway, it is still a mystery to me the reason why I'm not able to reproduce the behavior you reported :(
For sure something goes wrong during wiping operation and it quits suddenly. After that FF complete the operation deleting cache files from filesystem (ok, this is expected).
Did you noticed errors in the Error Console of FF ?

PS: I'm planning a new version of SS with a better (more secure) use of pseudo-random numbers. But this not relevant for your issue.

Thanks a lot for your tests

A plugin you shouldn't miss ! Rated 5 out of 5 stars

Beyond any discussion I've read here around the total effectiveness of such plugin, I think this is one anybody shouldn't miss in the set of those which make Firefox the most complete browser on earth so far.
I've just got a new PC here at work and in few days already felt the need for it!! ..
Note it down guys!
"Well done" to the developer! ..

Does it really wipes datas ? Rated 2 out of 5 stars

I liked the previous one very much.

But does yhis one really work like in the past ? After installing this addon, I no longer seee in Tools->Options ->Privacy->Settings the choice between 1 random or 3 DoD passes. Why ?

2 stars until this point becomes clear to me.

Version 0.3.4 will solve that problem : wipe type choice will be present in Privacy settings.
Available in one or two days.

It works well. The complaints are ridiculous! Rated 4 out of 5 stars

It does it's job as advertised. The complaints that it doesn't come with a sledgehammer to smash the entire hard drive are ludicrous. It only claims to wipe the cache using DOD algorithms. The critics of the DOD method probably are reacting because there are even deeper methods available now. A good analogy is marketers know that they can increase sales if they give a low, medium and high priced option- even if they really only plan on selling one of them. The very presence of another choice wildly skews the results. I would very much like to see any of the critics actually recover any data from this and post and prove actual data recovery...

Hoping for a FF 4.x version soon Rated 5 out of 5 stars

Thank you for reintroducing this feature that Mozilla dropped for no reason that makes sense. Hoping you will have a Firefox 4.x version at your earliest possible convenience. Impressively elegant functionality, even if some have critiques that may have validity but overlook that something is better than nothing. Thanks again.

What's wrong with DoD? Are there legitimate reports of data being recovered after having been overwritten using this algorithm?

In any case, the complaints that Secure Sanitizer is not able to wipe 100% of a hard drive are absolutely groundless and insane. You may as well complain that your sneakers don't take you to the moon. What's wrong with people?

My only gripe with Secure Sanitizer is that there's no Cancel button, for those times when wiping is taking longer than it's worth.

We'll see... Rated 4 out of 5 stars

It seems like it works great. I agree with others though, the DoD algorithm is a bit dated. But it's better than CCleaner. However, do you have plans to create a Chrome version of this?

thank you for your beneficent minded contribution but Rated 1 out of 5 stars

edit: clarified for the simple

This extension CANNOT securely erase ANY file from an ATA drive by construction. It might happen to occasionally "sufficiently" delete a few files with ZERO user-certanty which files those are, but inaccessibility is radically limited in scope. Claims otherwise are foolish or specious at best.

DoD 5520 is a bit dated. See NIST special publication 800-88 [from 2006].

Damaged sectors DO contain data and CAN be recovered with forensic technology. Those sectors might contain [fragments of] the very information one used this extension to attempt to eliminate.

This can NOT erase *all* data from an ATA drive -- nor can any similar "erase software". Here are a few terms with which to familiarize yourself:

Device Control Overlay
Host Protected Area

^ Not a complete list.

Use a RAM drive for cache. Problem solved.

The only way to ensure data destruction on an ATA drive is to DESTROY the drive itself.

This review is for a previous version of the add-on ( 


Interesting note!
The aim of this extension is simply to wipe FF cache files, not to wipe whole HD (like other erase tools do). So I don't care if it is not able to access "Host Protected Area" or "Device Control Overlay" areas because FF cache is not stored there.
A different story is for G-list sectors. It's possible that during FF usage some sectors becomes unreadable and are added to G-list. Ok, these sectors cannot be wiped by this extension. On the other hand these sectors are damaged and unreadable, so I assume it is quit difficult to retrive original information.

Anyway I agree with you: it is not possible to destroy infos via software with 100% of certainty.

Would like very much to see this in action. Sounds like a companion to CCleaner...but maybe more convenient?
