Chrome Private Mode Not Quite Private

wiplash writes "Google Chrome appears to store at least some information related to, and including, the sites that you have visited when browsing in Incognito mode. Lewis Thompson outlines a set of steps you can follow to confirm whether you are affected. He has apparently reported this to Google, but no response has yet been received."

    So, since the example in TFA didn't restart Chrome between incognito windows, I decided to see what happened when I followed the steps with "4.5 Exit chrome completely, then restart", and can confirm that even when Chrome fully exits and is restarted, it remembers the zoom level used in a URL only ever visited in an incognito window.

    Do you believe every piece of FUD that comes out of sopssa's mouth? By default yes, everything typed into the address bar is sent to google which is how their autocomplete for searches works. If you just don't want it sent to google, change your default search provider. if you don't want it sent anywhere simply uncheck 'use a suggestion service to help complete searches and URLs typed in the address bar' in the Under the Hood tab of Options.

  4. Reproduced it here just fine by droopus · · Score: 5, Informative

    Exactly as reported.

    I'm using 5.0.375.29 beta on an Air running 10.6.3 over wifi.

    Went to cheese.com (the #1 resource for cheese!) and the zoom held.

    Additionally, when I opened a new tab in non-incognito mode, the zoom STILL held, so there is definitely some communication between regular and incognito windows.

    I'm devastated that my secret cheese browsing is now public.

    There's always Chromium; I run it on Ubuntu. For Windows there's SRWare Iron. I'm not sure which is the preferred build for OSX; perhaps Crossover Chromium. TFA doesn't say whether Chromium is affected. Some comments under TFA state that the effect lasts only until Chrome is restarted, suggesting that the information is stored only in the memory cache.

  6. The bug by trazan · · Score: 5, Informative

    Here's the bug in question, filed about 2 weeks ago:
    http://code.google.com/p/chromium/issues/detail?id=43107
    Seems like someone looked at it, prioritized and classified it (eg pri-2, internals-cookies).
    What's the big deal? It's just a bug that needs to get fixed, not a huge conspiracy by Google.

  7. Pitchforks down, please, no story here by TerrenceCoggins · · Score: 3, Informative

    TFA only mentions zoom levels as being stored -- not any other info from users' porn-mode browsing session, just zoom levels. Chrome recently began saving users' zoom levels (if I'm not mistaken) so that pretty much explains that (while conveniently also accounting for why users of earlier versions may not experiencing this phenomenon as well.) We're all waiting for google to slip up monumentally (or "pull a facebook," if you will,) but unfortunately we'll have to wait another day.

      If it remembers zoom levels for particular websites, it must remember the websites themselves. That also means someone can potentially obtain a list of URLs you visited in incognito mode.

      That defeats the entire point of incognito mode. It's not supposed to remember anything.

  8. Re:The Phone Company by Sancho · · Score: 3, Informative

    The article shows that a per-site setting (page zoom) persists between incognito sessions. That's all. No mention or even speculation that Google is storing that information on their servers.

    That said, Incognito was never meant to be private browsing from Google. Your search queries still get send to your search provider (imagine that!) and auto-suggest will still work. What Incognito mode is for is to prevent your wife/brother/sister/boss from seeing the sites you use. This has been discussed to death already.

    Um, yes, and AFAIK you have been able since almost the beginning. Wrench-->options-->under the hood --> "Use suggestion service...".

    Just for the sake of putting this stupid argument to rest, I tested it with wireshark, and yes, unchecking that box immediately causes chrome to cease sending URLs to google. In fact, with all the boxes unchecked, it appears that the only traffic sent is directly to the websites that you are fetching.

    I like how your "yet" implies that that hasnt been there from practically the start, though, or that you cant just use chromium if you are really that worried about it.... really some quality FUD there.

    So, maybe Im just being an apologist here...
    But while I did verify this, and can see some disk writes in ProcMon to a tmp file (which seems to be deleted on close), is it asking too much to have a little more info before running off and declaring it to be some additional nefarious way to collect info? Any packet sniffing, or even seeing if it can be replicated in chromium or Iron? Any effort to see ANYTHING AT ALL of whats going on, or whether that data is stored anywhere except the "magnify websites to this level" database?

    I mean come on, I know Google is the new "cool to hate" company, but a 1 paragraph blog entry with NO technical details whatsoever makes REALLY poor outrage material.

    That's the point -- the Queen can't just step in because she doesn't like the current government, it's only if the shit really hits the fan, as a last resort. For example, if an elected government tried to turn itself into a perpetual dictatorship without the support of the public, she could go in and kick some ass.
