552903 - Iceweasel takes long time to load webpages when tcp-sessions number is restricted

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Etis]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.18) Gecko/2010021719 Iceweasel/3.0.6 (Debian-3.0.6-3)
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.18) Gecko/2010021719 Iceweasel/3.0.6 (Debian-3.0.6-3)

I use Debian Lenny. My internet connection has a limit of 10 open tcp-sessions simultaneously.
For about a week I have a problem using Iceweasel (see picture). When I open a webpage IW stucks for several minutes after opening some of images on it, and I can't open any other webpages in other windows/tabs at that time.
"ss -t -a" or "lsof | grep TCP" commands show a bunch of "ESTAB" tcp-sessions but no data flow.
Konqueror works fine opening the same pages.
tested in IW 3.0.6 (lenny) and IW 3.5.7 (lenny-backports).

Reproducible: Always

Steps to Reproduce:
1. restrict your internet connection to 10 open tcp-sessions (like some satellite internet providers do).
2. open any website with lots of pictures (e.g. images.google)
3. open it in any other browser (e.g. konqueror)
Actual Results:  
IW stucks opening the webpages while other browsers don't.

Expected Results:  
maybe IW should close tcp-session right after the file (e.g. image or css-sheet) was downloaded.

I also use addons adblock, flashblock, noscript, downloadhelper, and umht. But that bug works even without any addons.

Please report to debian first, or test using an official mozilla build of firefox. You are using an old version of iceweasel, and iceweasel has some significant differences from official firefox build. So, either report to debian first, or try a mozilla build.
