User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6b) Gecko/20031208 Firebird/0.7+ Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6b) Gecko/20031208 Firebird/0.7+ The behavior seems to have become worse a few weeks ago. If I click on a link (or open a bookmark, or allow SessionSaver to restore a link, etc.) and it does not resolve (Correctly? In time? ???), the throbber and the spinner on the tab continue to spin forever. (What used to happen was the link was unavailable until you reloaded the page. However, all other links worked normally.) If you click another link, or hit STOP, or hit RELOAD, you are hosed becaue no other link will work until you restart the browser. All menus work and respond normally. If you click on the "Red X" to close Firebird, the window closes immediately. However, if you attempt to restart Firebird, you get an error that someone is already using your profile. You must use Task Manager to kill the zombie Mozilla thread. Now you can restart Firebird. I am using a P4 with HyperThreading turned on. I cannot find it now, but I saw an entry in a thread on Mozillazine where someone suggested the zombie thread might be caused by a problem with hyperthreading. Reproducible: Sometimes Steps to Reproduce: There is no known reliable way to reproduce the problem. It *seems* to be related to network load. The behavior is as if a link is unable to resolve or load correctly (or in time). However, this exact same link and page will load correctly most of the time. Very frustrating. Actual Results: When the bug does happen, the throbber and tab spinner continue to animate forever. Clicking on any link, selecting a bookmark, clicking on STOP or RELOAD, does nothing to resolve the problem. No matter what you do (even if you have multiple Firebird windows open) will allow you to browse to any other page. You must close Firebird and then kill the zombie thread before you can restart Firebird. Expected Results: If a link cannot be resolved correct, an error should be generated. If a link cannot be resolved in time, an error should be generated. Regardless of cause, the user should be able to click on any other link, select a bookmard, or RELOAD the page successfully. When Firebird is closed, there should be no remaining zombie threads. At times, the problem happens more frequently. It is possible this is due to network load on my PC. The problem eventually happens EVERY TIME I try to use Firebird. I have tried many different versions (both standard and optimized) and the problem remains. Could this be related to P4 HyperThreading??? (No other application has this problem.)
i can confirm that i am seeing the same problems on the latest nightlies while running hyperthreading. when HT is off, the pages seem to load fine or give an error instead of going 'zombie'.
I have been seeing this behaviour recently. I am using: Firefox 1.0, Windows XP SP2, notebook with Via Antaur processor. The web site that is causing me most grief is 'www.carsales.com.au', when selecting options from the pulldown menus on the main page. Reproducible: The fault occurs on the specified web site about half of the time. Note: two Java icons appears on the task bar (Java 2 Platform SE, Version 1.5.0 (build 1.5.0-b64)). When zombie process killed only one Java icon remains.
I am also seeing this behavior (started when upgraded to 20050414 Firefox/1.0.3) This behavior appears only when I am in a Windows session (XP Professional SP2, Gateway Laptop, P4, 3.0 GHz, 512MB ram). Same computer has a Linux partition in which this behavior does not occur. One site that can cause problems is http://www.allstarpuzzles.com/picture/index.html (any of the puzzles off that page) Windows installation is running Java 1.5.0 (build 1.5.0_02-b09)
I see this problem every few days, usually following moderately heavy browsing at Yahoo News. I have been unable to find a specific page that triggers it. When it occurs Mozilla refuses to load any further links and the dot on the cursor stops blinking. I can still close windows, but when I close the last one the Mozilla process refuses to exit, and I have to end it. I am using Mozilla 1.7.12, but have seen this at least as far back as 1.7.10, and probably much earlier. I do not have HTTP pipelining enabled, though I do have HTTP 1.1 enabled. I have just switched to HTTP 1.0 to see whether that ends the problem.
(In reply to comment #5) > and the dot on the cursor stops blinking. < That should read: "and the dot on the *tab* stops blinking".
(In reply to comment #5) I have turned off HTTP keepalive, and the problem still occurs. I am now trying HTTP 1.0 with no keepalive.
(In reply to comment #7) > I have turned off HTTP keepalive, and the problem still occurs. I am now trying > HTTP 1.0 with no keepalive. The problem still occurs. In summary, the problem occurs with all combinations of pipelining, HTTP 1.1/1.0, and keepalive.
(In reply to comment #2) > i can confirm that i am seeing the same problems on the latest nightlies while > running hyperthreading. when HT is off, the pages seem to load fine or give an > error instead of going 'zombie'. My machine is an AMD Turion MT-37, which does not support hyperthreading, so that's probably not the cause -- unless we're seeing two different bugs that produce the same effects.
The bad news: I forgot all about this bug. (My apologies.) The good news: I cannot remember the last time this bug occurred. (Hooray!) Unfortunately, I have no idea which version of Firefox corrected the problem. The problem is gone (for me). I am currently using the following version with no problem: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:188.8.131.52) Gecko/20070725 Firefox/184.108.40.206 Thanks to whomever corrected this!
