There many discussions in the web about it

My Mullvad browser, which is a fork of Tor, deletes favicons after closure. I just tried it on a private window in Firefox, and it also clears them. (Network tab displays transferred bytes, as opposed to "cached".) Could you verify in non-private Firefox (if you have it), as well? At the moment, I cannot clear my browser's cache, because I'm working.

Edit: It also clears favicon cache in Tor.

The best answer is to not use spyware browser Chrome.

It doesn`t work.

As a web developer I have seen favicon remains in the cache even if you change the file, use Ctrl F5, browser cache, etc....

There many discussions in the web about it

I found some other solutions, on the server side, which might be a solution for eXch in this case.

Something like this should be in the .htaccess file

Code:


    Header set Cache-Control "no-cache, no-store, must-revalidate"
    Header set Pragma "no-cache"
    Header set Expires 0

1. Where is that supercookie usually found in browsers and how to delete it manually?

Not sure what you mean by "where", it is stored in the same way as other cookies. You can delete it by clearing the cache.

Close Chrome
Open your User Data folder

Run Chrome
Visit sites to force the icons to be re-downloaded

2. Does this supercookie have any effect on the Tor browser and does it remain in it after we close the browser?

Unless specified otherwise, nothing related to your previous browsing remains in Tor, after you've closed it. It clears cache on closure.

Honestly, I didn't even know that icon had an official name, much less that it could be used to track users. What is particularly worrying is that it cannot be deleted in the usual way, and I have two questions about that :

1. Where is that supercookie usually found in browsers and how to delete it manually?

2. Does this supercookie have any effect on the Tor browser and does it remain in it after we close the browser?

Most browsers allow to search for a specific tab which might be faster than scrolling through all your tabs and finding one by icon. Next option is to search in bookmarks or put a favorite on your new tab page, whatever suits your needs.

Could a favicon be a privacy issue, maybe on other pages? (Maybe I confuse a few things; the favicon topic is a bit blurry from the top of my head. I have some sort of vage memory of something I read in the past where a site could exploit somehow the existance of a favicon in the browser's cache to obtain ... whatever...).

I guess I wouldn't mind a nifty favicon either... Wink

I didn't know about this .

I researched about it, and it is true. Websites can really track users uaing a script under the favicon.

I honestly didn't even know about this until now. (I never even researched this topic) Although now that I think about it, the favicon often remains for a long time, even if I remove it from a site I manage.

But favicon addition would be great, since people who take their privacy seriously probably use Tor Browser anyway to visit eXch.

Easy privacy fix: don't add the favicon icon to the .onion site.

I would accept this option.

Favicon is basically a supercookie which persists over cleaning browser cache and crosses incognito mode of browsers.
However, to be used like this, the website must be willing to do it.

A good idea would be just to remove it enterily in privacy oriented projects.

Yes, it's one of less-known privacy issue.

Quote from: https://privacytests.org/

favicon cache

A favicon is an icon that represents a website, typically shown in browser tab and bookmarks menu. If the favicon cache is not partitioned, it can be used to track users across websites.

But favicon addition would be great, since people who take their privacy seriously probably use Tor Browser anyway to visit eXch.

If I can give one suggestion to the eXch team.
Is there a possibility to add a unique favicon for your site? I usually have a large number of open tabs (I'm pretty sure I'm not the only one) and a site icon would help me a lot in easier recognition of exch site tab in the browser.

I believe eXch are not dodgy, however the total amount you called is a little too high to believe without verification.

Have you seen their proof of reserves? It's not a far stretch to go from that amount in Bitcoin to a large number of ETH if someone exchanges a large amount.

That's fair enough although it's not half the amount I was told here- if they can implement/improve on some of the things I highlighted here it would do a lot of good to them.

@paid2 you only provided ETH reserves not the entire pocket. Cheesy

eXch officials have already emphasized that they will provide proof of reserve if necessary. They have already proven their seriousness many times, I guess they don't need to do it just to satisfy someone's curiosity. It is also written on their website.

In crypto, do not trust but verify! Or have we changed the standard Bitcoin community phrase? Cheesy

Look at the whole thing in the simplest way. The total reserves held by eXch are over 400 BTC ($36+ million currently) one

This is huge! Anyway to verify this?

I would not bother to verify [unless my amounts are larger or nearly large to the showed amount] but will at least put some trust. eXch is in the forum from long time and they already created a sense of positive influence. The only thing I will worry about is the authority and in such type of case the service has no hand. Other than that, the service itself earned the trust to believe a number that they put on their portal.

Quote from: exch.cx

All the listed reserves belong to us and are currently allocated on our wallets/nodes. We do not depend on any third-party liquidity providers. We can provide a proof of reserves on request.

@Igebotz, absolutely all the ambiguities you mentioned here in the last few posts are quite transparently expressed on their website. Wink

Yes, we've seen a lot of Non-Kyc exchanges like this one disappear or be targeted by the government, making it too dangerous to remain in the queue. Every one second in a system like this is dangerous. My initial thought.

I think many more could fall before eXch needs to worry. I haven't known any other exchange operator that takes its operational security as seriously as eXch does. By the way, if you're genuinely worried about your funds, you could use the guarantee offered by OrangeFren which insures your deposits.

I'd share your concerns if I had to deposit coins on a crap service like ChangeNOW or FixedFloat, but I don't see anything with eXch that would justify it, even after so many years of service.
