Thank you for the explanation of your issues with CTFMON.EXE, therube. That's all I wanted to know.

Glad to help, and to hear download.com is working for you now. :D

For me it's ok. You and therube did a great job. :-) Kudos to you both.

This helped. :-) I got a nice clean prefs.js now. Got rid of a lot of configuration rubbish that way, too. Thanks!
You are welcome and I am glad that it helped you. Yes this is also a nice way to clean out old left over settings too (which can also be done by going to about:config and individually selecting Reset but you might accidentally reset something you actually need) so this would be the least destructive way to go.

It is entirely up to you. If this resolved your problem and is something that hasn't happened to you that often, I would say let it be and move on. However, if this is something that is happening ALOT and is something that is a source great interruption for you, send me the old pref.js file through PM and I will take a look but I think we can safely assume that during multiple updates, long term use and some extensions coming and going, something got tweaked wrong and got corrupted. Probably, nothing to lose sleep over and you can safely move on, but up to you.

This may be overkill but I have used it to fix similar situations. Go to your profile folder, rename pref.js to pref.bak and then open up your Fx into the original profile and it will have NO SETTINGS. You have to reconfigure all the plugins and it works fine. Now I know many just say, why don't you create a new profile, install everything again and do it that way, I don't know but some prefer to keep everything there and just do this part, to each what ever works but this should resolve the problem in that profile.

You've got that .NET plugin loading (for whatever it is that it may do)?

Also take a look in Task Manager & see if CTFMON.EXE is running.
Kill it & see if there is any change.
(You may be using it? & if you kill it & need it, you'd need to restart it back up. If you don't need it, best to stop it entirely IMO.)
The .NET plugin is to process and handle ClickOnce installation files created with Visual Studio and such.

If everything was blocked, it worked. And if everything was allowed, it worked too.
This is exactly the same position I was coming from, I am sorry you mistook it as meaning it was a NS functionality issue. It was not, just letting you know that regardless of allow or not allow with NS, it works fine. So there might be a corruption, some interference from another addon or possibly the browser getting stuck by a burden placed by the script itself.

I went into the new profile and activated all plugins. The page loads as it should!

I admit, I'm stuck. I've got no idea where to look further. What can it be that makes the difference between the two profiles if it's neither add-ons nor plugins?

Because it's been known to, because I have seen it interact poorly with other (certain) softwares.

And if you have no need for what it offers (alternative language whatever it is), then it serves no purpose to have it running.

Me, I don't use Office, so normally I wouldn't have ever seen it. But IE7 (& IE8 I assume) also causes it to spring to life.

Jerico being -DE & being in an English forum, or someone else, say a linguist, who needs what CTFMON.EXE offers, may not want to kill it, but otherwise, it's just taking up space, using resources ... & possibly interfering in some odd way ... with FF & download.com.

So you kill, test, & if that's it, you've found something out. If that's not it, then the problem is elsewhere yet.

Just another data point. I'm unable to reproduce jerico's issue either. Following most of jerico's steps to reproduce in a test profile: default profile with the NS 1.9.1.6 as the only extension, i.e.
- I reset NS to default settings (including NS's whitelist)
- I loaded http://download.cnet.com/AVG-Anti-Virus ... 20142.html into the only open browser tab
- I added com.com, download.com and cnet.com to NS's whitelist

Result: Page loads normally with no persistent cpu max or large memory use.

I also loaded the page into a clean test profile: default theme, no extensions, except for the one automatically installed by Free Download Manager into all of my Firefox profiles. Same result.

Note: CTFMON.EXE is running because it's automatically started when I login to my account. I don't see why it's singled out as possibly problematic, or why the user should stop it entirely.

...oh yes, and of course I used the latest version of NS (1.9.1.6)...

Re: download.com freezing with noscript activated

by jerico » Thu Apr 02, 2009 2:53 pm

Ok the result is:
- I de-activated all add-ons except NS
- I reset NS to default settings (including NS's whitelist)
- I rebooted my PC
- I temporarily stopped potentially interfering background processes (e.g. anti-virus, firewall)
- I closed all other programs
- I loaded http://download.cnet.com/AVG-Anti-Virus ... 20142.html into the only open browser tab
- I added com.com, download.com and cnet.com to NS's whitelist

The symptoms are as follows:
- after adding the above sites to whitelist, the page partially loads, then FF freezes
- one CPU core stays at 100%
- the task manager shows me that FF slowly accumulates system memory until something like 400MB

That's it.

Ok, as you couldn't reproduce the problem I'll try to make it easier to reproduce. Give me a little time for me to try around what's the minimal configuration that still produces the effect. Then I'll come back to you, ok? It may be some funny interaction with other add-ons as well. I'll try to find that out.
