After surfing for awhile, Firefox begins to exhibit weird image caching behavior. I used Google Maps as the URL because it's where I most commonly see it (presumably realted to the large number of images being shuttled in and out). Incorrect images will begin to appear where others should be... a map of New Jersey in the middle of California, etc.-- all images I've seen before. In a few instances, images from other browser windows and sites have appeared, scaled to the inappropriate size. In most cases, these are obviously images from other sites I've been on, so I don't feel this is a problem with Google.

Forgive me if this is a dupe, but I couldn't find it anywhere else -- I've noticed it on my work and home machines, both of which run (one on Win2K, one on WinNT).

Reproducible: Always

Steps to Reproduce:
1. Navigate to Google Maps after a long browsing session.
2. Move the map around, zoom, etc.
Actual Results:  
Incorrect images appear in the place of pieces of the map -- sometimes from Google, sometimes not.

Expected Results:  
Displayed the correct image (cached or otherwise).

Running some extensions: GMail notifier, Web Developer. I haven't reproduced this on a clean install, but only because the time involved would be significant -- I use a different plugin set at home and see the problem there as well.

I finally captured this occurring -- the top portion of the bar turns into a Google Maps image of Holland that I was looking at about half an hour ago.

This is on the same UA as the original report.
I'm seeing this exact problem with Firefox 2.0 as well.  After I clear the cache, the problem goes away, until the cache fills up again (I would guess).
I've been seeing this as well, on sites like Facebook (lots of images), Slashdot, NY Times, and others. Haven't come across it on Google Maps yet.

Here's a clearer one (I'll stop spamming soon) -- a map of the Bronx where the Google logo should be. It is often Google Maps images, but I guess that's statistically likely, considering how much I use it. Sometimes it's other random images too (I've seen photos of houses and stuff, so it's not limited to the one domain).
I see this same strange bug of incorrect cached images displayed when zooming about tiles-based map sites, such as Google or This is through a work proxy (Qbik WinGate) in NTLM authentication environment.
This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
