At this time, the browsers times out when hitting blocked sites (ad servers). It would make browsing much smoother (and faster) if mozilla recognized a "REJECT" from iptables and moved on. FYI, I am using reject, not deny. And I have tried a few --reject-with options without success (well, the ads are blocked, but mozilla still times out, then proceeds with processing the page). Reproducible: Always Steps to Reproduce: 1. Put something like this in your iptables start script: # deny ad(s).doubleclick.net DoubleClick Ad requests iptables -A OUTPUT -d 220.127.116.11/24 -j LOG --log-prefix "FIREWALL:OUTPUT-ads " iptables -A OUTPUT -d 18.104.22.168/24 -j LOG --log-prefix "FIREWALL:OUTPUT-ads " iptables -A OUTPUT -d 22.214.171.124/24 -j REJECT --reject-with $rej iptables -A OUTPUT -d 126.96.36.199/24 -j REJECT --reject-with $rej where rej=icmp-host-prohibited 2. Hit any site using doubleclick ads. 3. Wait a minute or so for mozilla to time out then finish rendering the page. Actual Results: The page took forever to load. Expected Results: Acknowlege the iptables REJECT and continue rendering without the timeout. None applicable.
if you're blocking with a firewall, this isn't "Image Blocking" ==> Networking

*** Bug 194026 has been marked as a duplicate of this bug. ***
A few notes of clarification. This is my first bug report, so if I sound all jacked up, I apologize. I assume a dialog box will be opened informing the user of the REJECT. Is it difficult to add a "Don't remind me again" check box for this? I'll take a look at 1.2.1 source (it's what I'm using) and see if I can help, but my C skills are a little rusty. Cooper.
I added an equivalent firewall entry to block www.mozilla.org and tried to load http://www.mozilla.org/images/mozilla-banner.gif with linux trunk suite 2005041305. It takes a few second to show an alert dialog that it could not contact the host. I get the same behavior with 1.2.1. I'm guessing that the difference with doubleclick is that a page might reference multiple images and/or scripts. I tried other tools like wget and curl and they also take a few seconds to give up, so this really looks like a linux networking issue rather than any problem with networking within Mozilla. resolving INVALID -- this is not a Mozilla bug
