Created attachment 619250 [details] Show wrong icon on tab for google User Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:18.104.22.168) Gecko/20110420 SeaMonkey/2.0.14; Firefox/5.0.0 Build ID: 20110420224920 Steps to reproduce: Open Seamonkey, open a few tabs. Go to different websites that have favicons. Actual results: Hit the browser back button once, that tab retains the previous sites favicon. This works the other way around as well, if you go forward the last websites favicon is displayed on the tab. However if you go forwared or back more than once the icon on the tab does update. But the next forward/back it does it again. This can be confusing when you have lots of tabs open and are looking for the site specific icon. Expected results: The tab should be displaying the correct site favicon on the tab at all times, not the previous icon when using the forward/back buttons.

Yes, I started noticing this beginning with version ~2.2. The most current version 2.9 does it too.
Confirming problem on trunk Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20120425 Firefox/15.0a1 SeaMonkey/2.12a1 1) Visit somewebsite.com with favicon 2) Go to google.com, favicon is correct 3) Press back button, previous site with it's favicon also rendered correctly 4) Now press Forward button, and Google get favicon from previous site on tab
Hmm. Neil, is this a tabbrowser bug?
Actually this looks like a regression from bug 660618, which landed in 2.2; what's happening is that we're no longer clearing the previous favicon when we're navigating through the bfcache. For consistency I suppose the easiest fix is to always remove the favicon (if the page is blank then it won't have a favicon, so no change there).
Except that that's suboptimal because we then have a slight visual glitch when navigating between two pages with favicons...
Created attachment 620246 [details] [diff] [review] Proposed patch At this point of the code we're normally turning off the busy animation, so we're not expecting there to be an image set on the tab. But of course bug 660618 changed this, so we're not busy, and any previous image is still there. This looks like the best place to remove it.
