Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Lisa]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6 (.NET CLR 3.5.30729)

Since the latest Firefox update (Firefox 3.6.6) I am not able to download any files. I do NOT use a download manager.

When trying to download a file, the download window opens and as soon as I click the save button (in German: Speichern), I do not get any response and Firefox crashes.
Then I am not even able to close down Firefox or restart it. I have to completely shutdown and restart my computer with Windows task manager or "Process Explorer" (from www.sysinternals.com )
When starting Firefox again after restarting the computer, my previous session is not saved anymore. In my download folder are instead of the rar file I intended to download, two files containing 0 Bytes:
- Examplefile.rar
- Examplefile.zip.part

Everything worked fine with the former version (Firefox 3.6.5). 


Reproducible: Always

Steps to Reproduce:
1. Click on a download link
2. Download window showing the download folder on my computer opens
3. Click on the button to save the file to the download folder

~~~ CRASH ~~~

Actual Results:  
Firefox gives no response and crashes. I cannot close down or restart Firefox, I am forced to shut down and restart my computer. After computer restart, my previous Firefox session is not saved, and the file I intended to download, has not been downloaded.

Expected Results:  
It should have downloaded a certain file.

I have "Zone Alarm Security Suite" running (firewall, anti virus and anti spyware), and also "Trojan Remover" ( from www.simplysup.com ).

Before this bug occurred, the only program I had changed, was Firefox with the update to version 3.6.6

I am not receiving a message telling me in which module Firefox crashed. Maybe I could look this up, by I don't know how to. Please let me know how it is possible for me to find out the module, in case you need this information too.

How can I download files for the meantime. I really need to on a daily basis.

Please open about:config (enter as URL), confirm the warning, enter "scan" in the top filter bar and change browser.download.manager.scanWhenDone to false.

>Everything worked fine with the former version (Firefox 3.6.5). 
There is no Firefox 3.6.5, we only had 3.6.4 and the difference between FF3.6.4 and FF3.6.6 is only a changed timeout options for plugins.

>Then I am not even able to close down Firefox or restart it.
I know that can't be a Firefox bug with this information. The Firefox process hangs in some third-party code that runs with kernel privileges and I think it must be your AV scanner. The changed option above disables the scanning after a download finished.

@ Tyler Downer:
What is the difference between crash and hang?
I cannot do anything within Firefox. It sort of freezes, and I am not able to click anything or close or open another session of Firefox with a task manager.

@ Matthias "matti" Versen:
I looked through all the menus of Firefox and Zone Alarm, but could not find anything related to  this:
"Please open about:config (enter as URL), confirm the warning, enter "scan" in
the top filter bar and change browser.download.manager.scanWhenDone to false."

Could you please possibly tell me where I have to open the menu and how it is named in German? I only use German versions of Firefox and Zone Alarm.

Thanks in advance :)

I just downloaded the latest update from another browser and updated to Firefox 3.6.7. Now downloads seem to work. I do not know how and why this happened, but my problem seems to be solved now without making any changes except for updating to the newest version of Firefox. It's not the first time a computer of mine seems to work unlogically.
Thanks for trying to help :)

Might have been a bug fix in that upset. WFM then.

if firefox is still running, it didn't crash.

hang= the application itself is in an internal loop and doesn't respond to user actions.
crash = the application is immediately gone and you get a crash dialog.

>named in German?

Not in the menu, you should enter about:config as URL in the URL bar (die Browser Adressleiste).
But it's not necessary anymore if it works again.
