Mozilla will not restart after having been running for a while. Start it, browse, and close it down, and it will not restart. Why does this window keep telling me that my summary isn't descriptive enough - surely a summary should be short?

From Bugzilla Helper:
User-Agent: Mozilla/4.75 [en] (Win95; U)
BuildID:    20010327

After running Mozilla for a while, browsing sites, etc, if I shut it down and 
then try to restart it, it will not restart. There will be a process in task 
manager (multiple processes if I try to re-start multiple time) but the browser 
window never opens

Reproducible: Always
Steps to Reproduce:
1.Start Mozilla and browse with other apps running.
2.Shut Mozilla down
3.Restart Mozilla - will not open windows though process is running.

Actual Results:  Mozilla will intermittently not restart after being shutdown.

Expected Results:  Mozilla should be able to restart after a session

Is intermittent, but easily reproducable with some extended browsing in the 
first session.  This has been happening since the first Mozilla release. Is 
still happening with 0.8.1 full release.

dupe of bug 53952 ?

Can you verify in the task manager that when you close mozilla that the process
exits before you restart it.

Very often after a long usage Mozilla closes its windows but the process lives on.

[Why do i not see the extra info that the reporter just added when adding this
reply to it??]

Hmm, could be similar, maybe even the same cause, but I've had it happen when
there are no other Win32 apps that are frozen.

Reading further down it could be the same DDE problem, as I can see the mutliple
Mozilla processes in the taskmanager, so it seems to be some kind of system
blocking problem. However I think the main difference is that I can start
Mozilla, browse, shut Mozilla down completely and then it won't start again. 

I'll have to double-check to see if the Mozilla process is still running on
restart, but I don't think so. If I try to restart twice, there are only two
Mozillas in the task manager. There would be three if once was still going.

i'm more willing to bet that this is a dupe of mozilla not quiting when it's 
told to.

I've double-checked as requested. After shutting down Mozilla I check the
taskmanager to make sure there are no rougue Mozilla processes left. I try to
restart, a new Mozilla process appears in taskmanager, but no Mozilla window opens.

If I attempt to start Mozilla multiple times, I get multiple instances in the
taskmanager, but no Mozilla window. The only way to fix this is to reboot the

please try following 
the steps at
create two dwi files, one of when mozilla works, and one of when it doesn't.  
zip the two files and attach the zip here as mime type: application/zip

I've now noticed that if Mozilla enters this "refusing to restart" state, and I
start multiple copies, all but the first instance will disappear from the
taskmanager after about 30 seconds (version 0.8.1)

Ugh, I hate this bug. timeless, can you please look at again? It happens very 
consistantly for me when I am in Windows ME. I was hoping it was a 0.8.x 
problem, but today's nightly confirmed that it is still is there. I can provide 
debug info too, if necessary...

timeless, sorry for adding you to the CC list. Bugzilla is too smart for me 
now. Removing one of your addresses.

wow, not bad timing, please try the patch in bug 53952.
ideally it skirts the issue entirely.

Is this being built into the nightlies (and if so as of when)?

I'm not a developer so I can't build the code, but I can check the binaries.

Please don't tell me it was in the 01 May build as this just crashed on startup with GKDlayout.dll errors. :(

Otherwise I'll download and check it when I get home in about eight hours....

Can you update when it is checked in? Then I'll download and test ASAP.

I've just downloaded the latest nightly (ID 20010504) and I can't reproduce the
bug anymore. I've only been trying for a couple of hours, but under
circumstances that I would expect to show the problem fairly quickly. Something
has definately changed in the code that has prevented this bug from showing (at
least on my system). 

I'll keep checking and update again in the next few days.


Comment 19

18 years ago
Nope, the bug is still there - I got it to hang again in the same manner with the 20010504. It does seem to be harder to do now though.

Please update when your new code has been built into the nightlies and I'll test again.

This seems to have been fixed by the recent fix of 53952. Although the symptoms
were a bit different, looks the the cause was the same and I can no longer
reproduce this error.  
looks like this is all better now thanks to the DDE fix in bug 53952. WFM.
