Sometimes when downloading various files, whether it be pictures or videos, etc, Firefox hangs and freezes. It plain out acts crazy. It will be like this for up to 10 minutes at times. This script was found to be unresponsive during this time - chrome://mozapps/content/downloads/download.xml:68

The add-on that deals with FTP downloads installed in Firefox now is FlashGot. Other add-ons installed are Aniweather, Yoono and NoScript.

Reproducible: Always

Steps to Reproduce:
1. Right click on a picture, or download file in any other way.
2. 
3.
Actual Results:  
When the dialog box pops up, the browser just starts to act really awful, freezing and hanging.

Download normally.

Do you also see it in Safe Mode ?

I guess that it might be caused by FlashGot, in which case it's not a Firefox bug. The authors of FlashGot will be the ones that can determine what the root cause is.

Encountering the same on Windows Vista Ultimate 32bit- SP2, running on amd athlon 64x2 2.60GhZ, 3GB RAM,NVIDIA GeForce 8400 GS with 512MB . Alle Addons are deactivated.

Starting a download freezes Firefox (Mozilla/5.0 (Windows NT 6.0; rv:2.0b11) Gecko/20100101 Firefox/4.0b11). Using task manager to end the task doesn't work, have to use kill process to make it end. Reloading tabs on restarting, restarts download and freezes the browser yet again. Last two sites, where I tried downloading were Ati and AVG.

"A script on this page may be busy" when downloading

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Anyone else seeing this when downloading with FF 4.0?

A few hits on google but using FF betas, so far I can't find a solution.

The problem causes the download to stall for ~30 seconds before the error appears, after stopping the script all is well.

Any Ideas?

Nope.

Never have this problem at least while downloading, though I have come across this error a couple of times but that was while browsing.
	
Same error (ie script) rsinfo or it just that you visit some broken webpages (with other bad scripts)?


	
Script error. I don't know if the site itself was broken or not. I had to stop the script for FF to work again.


	
Point is rs, it's a specific script at a specific line unrelated to the website, my guess is your findings are entirely unrelated to my issue but thanks for the input anyway.

EDIT: I'm going to start looking at the addons I have just in case there is an issue there, I'll report back in a few days but if anyone else comes up with something in the meantime I'll be listening.


	
Try disabling any Add ons and see if it recurs. Then apply them one at a time to see which one is causing the problem.
I think I had that same verbage appear using FF 4.0 and it's running sweet as without any Add ons at the moment.
I'm waiting till Mozilla get's them compatible. Neil.


	
I have got the error with various Firefox version, and, never, more than once. I, always, stop it, and check not to bug me, again.
It has, never, happened with downloads. It got to the point that I don't, even, pay attention to the cause, since the problem does not reoccur.
For instance, today I was doing a survey, and when I clicked on one item, I got the error. I stopped the script, and the survey continued uneventfully, as another survey from the same site. It looks like Firefox started falling asleep, and I nudged it awake, lol.



	
I've experienced this when downloading drivers at certain OEM sites that use javascript to launch the downloads. For example, the file may come from the sites ftp directory and the download link opens a popup window with an "agree to terms" statement. When I've encountered this error it was when I had several simultaneous downloads going.

With javascript, it's possibe to initiate more than one window.open function using a single click. When clicking such a download link, the javascript starts the connection to the ftp server and opens the "agree" popup window, and a second script starts the download when the "agree" link is clicked, and possinly closes the popup window.

As I recall, it was at Intel's site where this occurred.

Done 3 times now Westside, the exact same error still appears .

@Tony, I think it must be one of my addons, the error/symptom appears with virtually every download.

 

	
Not sure if this is a coincidence or not but it turns out I had a previous (beta 8) version of 4.0 installed as well. Even though I was using the RC of 4.0 and subsequently 4.0.1 the problem remained but hasn't appeared since I uninstalled 4.0 beta 8.
