How are the standard ACL settings for the installationfolder C:\Program Files\Mozilla Firefox ?

reasoning: On my Win7 Prof. machine I have an entry for "authentificated users" who can write to that folder and I guess this is a security risk/no standard behaviour?
I stumbled upon this because of the newest update for Firefox.
My machine is able to update Firefox, when a user without administrative privilegs is logged in. The UAC is on the highest adjustment.
I guess this perhaps occures, because I transfered the user profile from a windows xp machine using the Microsoft User Migration Tool?
Please provide feedback for the standard user rights, which are granted for a clean Firefox installation so I can adjust my settings.
Kind Regards

I am assuming you've not been able to bring up Firefox at all after installing.
In my start-up command in the properties of the icon
I have the pathname enclosed in double quotes because of the spaces:
"C:\Program Files (x86)\Mozilla Firefox 4.0\firefox.exe" -p Firefox-Four
Is your download first install of Firefox or was it to update to Firefox 5.
Have you used Firefox before on your machine.
What happens if you just type firefox.exe into the '''Run...''' box from the Windows Start button (WinKey).

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can skip the step to create a new profile, that is not necessary for this issue.

Check the file name for capitalization or other typing errors.

Do you have any idea how to get rid of this annoying pop-up? I searched for that file name on Google, but nothing came up.
This only started happening after the Scareware program, Open Cloud Security, infected my computer a few days ago. My wife got into my registry to remove Open Cloud, but now I am left with this annoying Firefox problem. I have to close the annoying window TWICE to get back to Drudge.
This happens 6 times per hour.

When I open Firefox I receive the following message on the open tab: jar:file:///C:/Program Files/Mozilla Firefox/chrome/en-US.jar!/locale/branding/browserconfig.properties.

I have been slowly loading more plugins and extensions for Firefox, as I found that I had a conflict and Firefox would freeze. Two (2) days ago I used Firefox Sync for the first time. After I rebooted my computer, I found that when I opened Firefox I receive this message "jar:file:///C:/Program Files/Mozilla Firefox/chrome/en-US.jar!/locale/branding/browserconfig.properties."
I use Speed Dial as my home page and at the same time I received this message, Speed Dial stopped working, unless I click on the "open a new tab" button.
I opened the container for the file listed above, and I show that the file is in the folder.
I tried reinstalling Firefox in case there was a corrupt setting, however it hasn't helped

Caused by the Firefox Sync extension. Reset your Homepage to Default.

I can't uninstall Firefox(3.6.3) either through the control panel or by going to Program files/Mozilla Firefox/Uninstall and running the helper.exe, I have Windows 7 Home Premium(64bit)

I simply want to uninstall Mozilla FireFox 3.6.3. I tried both recommendations of using the control panel to add/remove program and running the helper.exe in Program Files/Mozilla FireFox/uninstall. I am running Windows 7 Home Premium Edition(64bit). When I tried to remove it using the add/remove program and helper.exe all it does is start for a split second(mouse pointer turns into circular loading icon) and then it stops.

Hi Guys,
I had this same problem too, and i want to share to all of you my own fix for this kind of problem;
(READ FIRST: ''This step will wipeout everything that mozilla saved on your computer including : password, history and bookmarks''.)'''
'''1. download the Revo Uninstaller''''''
- quick step guide for this:
select mozilla firefox, don't forget to uninstall everything that relates to mozilla including registry to clean them all up.
'''2. download mozilla firefox again'''
- AND REINSTALL. however on this stage, in some cases mozilla will not open at this stage.
'''3. Uninstall Mozilla firefox again NOW using control panel.'''
'''4. Restart the computer to refresh everything.'''
'''5. Reinstall mozilla firefox again, once you have received the prompt for "exporting or importing etc.. etc.. from Microsoft" that means its already working.. it will take around 5-10 sec to load up (in my case) .'''

When I click on my Firefox desktop shortcut, this message appears "The application or DLL C:\Program Files\Mozilla Firefox\MOZCRT19.dll is not a valid Windows image. Please check this against your instillation diskette". I cannot enter the program.

I believe that my question gave all the details. I am wireless in my home and the other computers connected to this wireless have no problem getting into Firefox. What is MOZCRT19?

clementem,
This means there is a problem with the files you need to run Firefox.
Try a clean reinstall:
1. Download the Firefox installer from [http://mozilla.com Mozilla.com] and save it to your desktop or other location.
2. Make sure that Firefox is closed completely
3. Delete the Firefox installation directory (On Windows, this is typically the C:\Program Files\Mozilla Firefox folder that contains "firefox.exe" and other Firefox program files and folders).
4. Reinstall Firefox by running the installer you downloaded previously.
Your personal settings, including bookmarks and history, will not be lost.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
* [[Troubleshooting plugins]]

A clicked link embedded in email (Outlook Express) takes forever to open in Firefox - the file type instruction is as follows: "C:\Program Files\Mozilla Firefox\firefox.exe" -requestPending -osint -url "%1". Why is this corrupted?

I believe the above problem started after a recent Windows update to my PC. I found a solution. First I open My Computer, Folder Options and then File types. File types affected: (None) Hypertext Transfer Protocol and (None) Hypertext Transfer Protocol with Privacy. When I change the Advanced Application to be Used by eliminating "requestPending -osint -yrl" from the entry, email links open almost instantly again. The problem is that the change I make is not permanent. Something keeps switching it back to the corrupted form and links don't work properly from my email.

I suspect you may need to modify your Windows registry settings to make the changes permanent. That said, I believe the command line options you wish to remove act as safeguards, I would caution against removing them.
'''-requestPending''' 
Tells the application that there will be a Windows DDE request to open the same url specified on the command line.
(Windows DDE is a method for transferring data between applications.)
'''-osint''' 
Tells the application that it is being launched by the OS shell.
'''-url URL''' 
Open URL in a new tab or window, depend on the browser option.
For more info, see [https://developer.mozilla.org/en/Command_Line_Options here].
You could try removing the -requestPending option (leaving the other options) and uncheck/clear the "Use DDE" checkbox. This may speed things up.
With regards to editing the Windows registry, please see [http://support.microsoft.com/kb/310516 here]. '''Remember to back up your registry first!'''
I believe you will need to modify the following registry keys:
Software\Classes\http\shell\open\command 
Software\Classes\https\shell\open\command 
Software\Classes\ftp\shell\open\command

Hello Susanne.
You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

After installing Firefox 3.6 I click on the icon to open it and get the error message "Windows cannot find 'C\Program Files\Mozilla Firefox\firefox.exe' " can anyone help?

This has happened after uninstalling Firefox, twice and downloading it twice.

Did you check if the Firefox file is in that location?
If it isn't there then do a clean (re)install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
If the file is there then do a malware check with some malware scan programs. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of the database before doing a scan.

Am getting this message when I attempt to open Firefox: "The application or DLL F:\Program Files\ Mozilla Firefox\nss3.dll is not a valid Windows image. Please check this against your installation diskette."

I had responded favorably to the upgrade message from Firefox but after the download I kept getting a Firefox message that I had to close all other instances of Firefox running before the installation process could complete. There were no other open Firefox programs! I re-booted and tried to open Firefox, and the Windows alert already cited started, and Firefox will not open.
Checking via Windows Explorer it appears that I still have version 3.6.

I resolved the problem. I went to CNet and re-downloaded the upgrade. It proceeded as intended and the upgrade is installed and running with no loss of plug-ins, bookmarks, etc.

While using Firefox, I keep getting a new window opening with the comment, Firefox can't find the file at /C:/Program Files/Mozilla Firefox/:þê+ìñLáR¸=%1AÞÀšlÀ£µSëä85r%1EI:U%0EÐL Vbj¨×mb¾Lvø5%13›H., how can I get rid of this file?

I can delete this window, but it keeps recurring, sometimes within 5 - 10 seconds.

The ONLY support for Mozilla programs are web sites like this.
The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.
If you want to leave feedback for Firefox developers, you can go to the Firefox ''Help'' menu and select ''Submit Feedback...'' or use [https://input.mozilla.org/feedback this link]. Your feedback gets collected at http://input.mozilla.org/, where a team of people read it and gather data about the most common issues.

How are the standard ACL settings for the installationfolder C:\Program Files\Mozilla Firefox ?
