IE7 inconsistently showing favicons?

    I recently upgraded to IE7 on my main PC, and am seeing that IE7 isn't showing favicons in the address bar or tabs with any consistency.  Sometimes they're shown, sometimes not, depending on the site.

    I've also observed that if I navigate to a site for which the favicon isn't shown, then quit and restart IE7, and navigate to the site again, then the favicon *is* shown.

    Does anyone have an idea of what the problem is and how it can be fixed?

    (BTW, I had IE7 beta 2, beta 3, RC1, and RTM on my test PC, and had no problems regarding favicons.  This is just happenning on my main PC.)

    Strangly I just started to see this happen, but it could be the fact that I have set the history to never save.

    I have the same issue. Although much improved, IE's favicon implementation remains fundamentally broken.

    Sorry, I'm going to disagree with that last statement. 

    We fundamentally re-wrote how favicons work, how they are stored, the algorithm for downloading them, etc.  We have a number of test cases and went through 3 betas with that code, fixing fewer issues with each beta and nothing after RC1. 

    We've had a few reports of issues post RTM and they've all been by design (favicon respects the no-cache header, for instance, and doesn't support PNG favicons).

    Give me a repro - site, behavior, settings.

    Even if it's completely different if it doesn't work right it's still broken.

    Channel9, or any site really. If I have IE open for an extended time the favicons just start disappearing from the title bar and tabs. Open a new instance and the issue is gone again. I've seen this happen on fairly vanilla installations too.

    I know how annoying this type of bug is since there's no clear repro. There's nothing I do to make the icons disappear; it just happens. But that doesn't change the fact that that is the case.

    I object to your extrapolation that your problem means favicons are still "fundamentally broken".  From my point of view, that's not justified by the evidence.  There are many ways to have one-off bugs, things that work for a million machines but break on one.  Favicons have not generated the scope of reports necessary for me to agree "yes, it's fundamentally broken".  IE6 favicons were fundamentally broken.

    So the feature has a problem that you can reproduce, so we need to figure out why you can demonstrate a problem and (many / most) others cannot.

    Could be a third party (it often is), could be some code problem with IE.   For example, one senior Microsoft exec couldn't drag-and-drop favorites around in Favorites Center but could in Organize Favorites.  It turned out to be caused by a particular Explorer extension for his Thinkpad's CD burning software. 

    So as always, run in Add-ons Disabled mode, check what BHOs are loaded, etc.   And as always, some things glom onto IE in ways Add-ons Disabled mode can't turn off, so even that doesn't guarantee no 3rd party code is running.

    Look at it from my point of view. In IE6, favicons usually didn't work at all due to the TIF issue. Now I move to IE7 and it's indeed much better. But I still see randomly vanishing favicons on four different computers and even more installations.

    It might be an add-on, but the problem in determining that is that it can take hours of usage for this problem to show up and some days it doesn't happen at all. If I run without add-ons, at what point do I know the symptoms are cured? I need most of my add-ons, I can't go running in no add-ons mode for weeks. (this reminds of a long time ago (more than a decade at least) on a campsite in france where they had a racing arcade game that was broken, but the symptoms only appeared after it had been on for about an hour. The techs would come to fix it, prod around with the connectors a bit, test it, conclude it works and leave. Then an hour later it was broken again. This cycle repeated a few dozen times, and then I left so I never knew if they ever actually fixed it).

    We run IE for hours / days at a time in various stress tests, and I don't recall that we encountered this issue.  We don't run stress with a variety of add-ons, though.

    If you could send me your list of installed add-ons, then we may be able to reproduce this in-house.

    Bruce, is there some way to clear the favicon cache (wherever it is) to force IE7 to start from a clean state?

    Maybe the "favicon" images are just leaving your cache?  You would be surprised how quickly a browser cache fills up, especially if your Internet connection is broadband or better.

    At the moment, I have eight tabs open. Seven have the correct favicons and YouTube doesn't. Doing a refresh (F5) doesn't fix it, Ctrl-F5 doesn't either. I tried re-opening it in a new tab and it still didn't work. Only after starting a new IE7 instance did the favicon return.

    I have seen that too... Even in RTM. After quite a time the icons just disappear. I have no addon installed (other then flash and the one that came with the IE7 installation). I'm running it on Vista RTM.

    One thing that was a little bit weird is that Adam changed the favicon of C9 and I needed to clear the cache before IE7 noticed the change... I'm often here and after a day the favicon was still the old, which made me to clear the whole IE cache.

    Yep, favicons in IE7 are definitely a mess.

    Sometimes they disappear at random, sometimes they get replaced by the wrong icons. I can visit a site and that site's favicon will overwrite the icon for a completely unrelated link in my favorites folder.

    Another annoying icon issue in IE7 is the one where IE7 HTML document icons are placed on top of any icons on a CD you insert, you see the CD file icons peeking out from behind the IE7 ones.

    These are all beta issues I expected to go away in the RTM, but no. I've got two machines running XP Pro (one with a US English version and US-EN IE7, the other with a Swedish XP edition and Swedish IE7).

    And no, I don't have any IE "add-ons", everything's factory default here.

    i jsut re-loaded xp from scratch and after adding all the sites i visit to the links bar - ones with icons - ( cbc, cnn, slashdot, news.com etc) are now - after one hour - all replaced with the default IE page icon.

    Favicons in IE7 are stored in an alternate data stream in the favorites shortcuts themselves (specifically, favorite.url:favicon).  I can't think of any reason why IE should be arbitrarily deleting them:   they aren't in the browser cache.

    Sorry Bruce but the favicons have been driving me mad too. I'm in IE7 and have a proper ico not a renamed gif or anything like that. My browser shows the icons of just about every site I go to for the first time but for sites I visit regularly including my own sites the favicon has vanished.

    When I type in mysite/favicon.ico it appears so I presume that means that there is nothing wrong with the icon file itself. Sounds like a caching thing but I can't work out how to resolve it. Any ideas?

    I have been bugged by similar intermittent problems with favicon problems (some missing, some wrong). It seems to only affect sites I have been to before. I have found the following fixed it for me ...

    1) Delete history (from Internet Options)
    2) Delete temporary internet files (also in Internet Options)

    If the above doesn't work first time, you may need to close and re-open Internet Explorer.

    FYI I am running IE7 on XP Home. But I think the above should work for other combinations of IE and Windows.

    Please let me know if this works for you too! If it does, I hope that Microsoft will look into this and patch this as it is REALLY ANNOYING!

    Good luck!
