I get error nsAppShell:Event Window:FirefFox.exe-Application on exit

So far this has has not been interfering with anything I do online. The message only appears after exiting. This is also just recently been happening in the last couple of days. I have also recently updated and still happens.
Just thought I would ask and see what I need to do.

NsAppShell:Event Window: firefox.exe- Application Error

Since downloading Ff4 when closing the program I receive this error message;
nsAppShell:Event Window: firefox.exe- Application Error
The instruction a "0x77f87f6d" referenced memory at "0x7c59c44a". The memory could not be "written".
Click OK to terminate the program.
How can I resolve this issue? I am on an older OS (2000 pro) with 2Gigs memory and P-4 processor (if this information helps).

What does nsAppShell: Event Window mean?

Many times when I attempt to close windows xp pro I get an error message saying (What does nsAppShell: Event Window). What does it mean? It prevents the closing of xp, and the pc continues to run.

DDE server window; itune.exe-application error

Can t open itune: DDe server window: itune.exe-application error. Then, instruction at 0x6d561040 memory could not be read. P.S.: the code change every time i click ok.

I do not know the answer to this, but if you are willing to to do some troubleshooting:
Which version of windows are you using?
XP vista or 7, 64 bit or 32 bit.
Do you have Quicktime? If so does Quicktime launch?
Did you change anything on your computer just before this problem started?
Please look in the Event viewer for a helpful error message.
To open the event viewer:
Control Panel>>Administrative Tools>>Event Viewer
Or type Event Viewer into the search box.
Then select Windows Logs>>Application
Open the Event viewer immediately after iTunes crashes.
The error message should be at or near the top.
Double click on it to open more information and press copy.
Paste the result into your post.

What is NSAppshell event window and how can I remove it? Have tried disabling all plug-ins and add-ons and it's still there and makes our computer slower than dial up!

Whenever I log off of my computer I get a message "NSAppshell event window," which slows down the performance of Mozilla and anything else we're trying to run on our computer. We're forced to log off and on to reboot and this happens nearly all the time. We have tried disabling all add-ons and plug-ins, to no avail. We are using Mozilla 4.0. Thanks for any help you can provide, as we don't want to go back to using Internet Explorer if we can help it.

I'd like you to upgrade to the latest version of Firefox, and tell me if that fixes your problem.

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

What does nsAppShell: Event Window mean? Firefox won't open for me at times and I need to restart.

When I return to my computer, Firefox won't open from the "standby" mode. It gives me the message saying "Firefox is already running, but not responding" and I need to log out or restart. Firefox is not running as far as I know. When I restart, a message comes up asking if I want to close "nsAppShell: Event Window". Once I end this process, it restarts my computer and everything is fine. This is very frustrating and happens all the time. What is "nsAppShell: Event Window"?

The OP asked this question 9 months ago and 850 other people have this problem. Why hasn't Firefox Support answered this question or commented?

Safari for Windows: WebKit2WebProcess.exe - Application Error

Scratching my head over this one...
Running the latest version of Safari 5 for Windows XP and after clicking the RSS feed icon in the address bar, Safari loads the page...and then hangs. I'll close the application and receive the following notification window:
WebKit2WebProcess.exe - Application Error
Quote
The exception unknown software exception (0xc00000fd) occured in the application at location 0x00ce30f8. Click OK to terminate the program.
Norton is installed on this machine (No arguments, please). Also using Malwarebytes Anti-Malware and SUPERAntiSpyware. I'm currently performing scans...starting with Malwarebytes. Not sure if its an infection but, it sure behaves like it may be.
Also...I do not have an issue using RSS feeds with any other browser.
Any suggestions?
Edit...
Just finished the quick scans with all programs listed above. No threats detected.

And Symantec and users say it is safe and fine to run multiple security suites I suppose too. There are reasons why you hear a thunderous number of people... I own and used a bunch and while they improve... even Kaspersky is no longer on my systems and replaced with Microsoft's own Security Essentials along with IE10 and Windows 8 CP.
Safari has never been a good multithreaded app, not on Windows or Mac OS.
There are some Google hits but then this is XP which if memory serves, was hard to maintain it and registry or without reinstall every 6-12 months.
I ran into "TDSS rootkit" or infected photos on Tumblr and in the end, the drive needed to be reformatted. I could not even install a new OS on another drive with that drive still active.

DDE Server Window: QuicktimePlayer.exe - Application Error

Good evening,
I bought an Iphone 4. BUT!!!!!!!!!!!!!!!!!!!!!
I have to install Itunes and Quicktime. Unfortunately, after the complete installation I have this error message... DDE Server Window: QuicktimePlayer.exe - Application Error
I tried to uninstall everything, no result. I tried to change session, the 2 other administrators have the same error message. I cannot run any Apple application (Quicktime, Itunes, Safary).
My computer technician told me that is is a Windows problem and I have to reformat and start everything over.... How can I avoid this??? Please help.

Strange. You see DDE errors associated with Safari every now and then (when opening email links), but it's very odd to see them feature as part of start-up errors for iTunes, Safari and QuickTime.
Let's try a few measures relating to fixing Windows operating system problems that don't involve a complete windows reinstall.
First, check to see that your Microsoft .NET framework is up-to-date and functioning properly, as per:
[iTunes for Windows: "iTunes was not installed properly. Please reinstall iTunes" message|http://support.apple.com/kb/TS3074]
Does that help with the start-up errors?
If not, perhaps try an sfc /scannow as per:
http://www.updatexp.com/scannow-sfc.html
Does that help at all?

After i have upgraded to Lion OS, this computer has become the worst computer on this planet. Everything is so slow as if i am in 1990's, where you can click on something and take a coffee break. Constantly get errors on MS Outlook and all applications

After i have upgraded to Lion OS, this computer has become the **** computer on this planet. Everything is so slow as if i am in 1990 where you can click on something and take a coffee break. Constantly get errors on MS Outlook and all applications are taking for ever to open up. If you guys can't fix it i am going to throw this out the window. Completely fed up with this. Have always loved apple but this is the worst experience i have with the MacBook Air and its not even 1.5yr old.

There are two ways to upgrade to Lion - one is to install Lion overtop of the existing Snow Leopard and the other is to erase the hard drive, install Lion, and then migrate your applications and user accounts. This second option takes a good deal longer than the first so the preferred method for most is the first method and in most cases it works fine. But not in all.
captfred has told you what I'd start out doing if it were my computer. There's a good chance that you can identify an application or plug-in that's causing the problem. Upgrading the involved item(s) can solve the problem. Of all the Lion upgrades I performed I had a couple that weren't completely successful even though I'd looked for programs and plug-ins that needed upgrading first. I missed a few but I found them after the fact and had happy computers.
There was one computer that still had problems. With this computer I reinstalled Lion right over the old version. (If you didn't keep a copy you'll need to download it first.) I still wasn't satisfied so with that computer I rebooted into the recovery partition (Command R after restarting) formatted the hard drive, installed Lion and then migrated. That did solve the problem.

I downloaded Firefox 4 onto my PowerPC G4 1.67GHz running Mac OSX 10.5.6. When I try to open it I get error message You cannot open the application "Firefox" because it is not supported on this architecture. I can't find my Firefox 3.6.16 I'm on Safari.

Use Tony's suggestion. I am running it right now and it is awesome. I love Mozilla but they basically screwed all of those older Macs over. Come on Mozilla. These Macs still work, and there are plenty of people with them out there.

I am trying to install Photoshop CS6 onto Mac 10.9.5 and get Error:16 when trying to launch application??

Anyone know how I can get Photoshop CS6 running on Mac 10.9.5 - I get error:16 when trying to run application after a complete removal and re-install??

Other Adobe programs should not cause this error.
Try this: Open Terminal,
copy/paste this into Terminal at the command prompt: sudo chmod -R 777 /Library/Application\ Support/Adobe
Press enter, and if asked enter your password.
Try opening Photoshop again.
If you do suspect older files, use the CS Cleaner
