The image being downloaded has no file extension, has a query string, and is a JPEG image (which makes that header sound even more weird). Here's the change between the first two requests and the third request:Īccept: image/png,image/* q=0.8,*/* q=0.5 The third request's Accept header was different. Upon browsing to an image directly, I saw three requests in Fiddler.
#Visit date history in firefox 40.0.3 windows 7
I did this after restarting with addons disabled on Firefox 31.0 in Windows 7 Professional 圆4. I'd like to explain what I'm experiencing separately. It's the favicon where the second request comes from. That's because Firefox won't show a preview image in the tab's favicon if any dimension of the image is 1024 pixels or higher. > If its smaller than 1023p, there'll be two requests. > If the image is bigger than 1023p, there'll be only on request. > So I've found an interesting thing about hat bug. (In reply to Lars Nielsen from comment #36) RewriteRule ^image/(+)?$ image.php?args=$1 Wondering if this slows my web-browsing experience in general for all sites.Ĭhrome/etc does not exhibit this behavour. Server is registering 2 hits for each page refresh.quite frustrating, it's making the hitcounts on my pages increment too fast.

Create a server that dynamically generates a 627x43 pixel PNG image returned as content-type=image/png.Ģ.
Without changing the server, if the request comes from FireFox 3.6.8 running on an XP 32-bit machine, only one request per refresh is made.ġ. If that generated file is placed directly in the file system to be served by IIS in a non-dynamic fashion, Firefox only makes one request per refresh. I have not narrowed down the exact size at which the problem occurs. A small, 627x43 pixel, image exhibits the problem. The behavior seems to be dependent upon the size of the PNG image returned. If we navigate to one of these URLs in Firefox 3.6.8 on Windows 7 64-bit, Firefox makes two requests to the server every time the browser is refreshed. We have a server that can serve up dynamically generated PNG images based on information provided in the GET URL.
