Cannot open firefox - or reinstall it - after today's update

After updating Firefox today to the newest version, when opening Firefox, I now get this error message: Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access them...I cannot open firefox. I downloaded it again, and when try to RUN, I get the exact same message. Please advise.

I uninstalled FF through control panel, deleted app files and exe. Then downloaded and installed latest FF from Mozilla. Works great now!

I still cannot get firefox to boot up after downloading the update. Get message that I must restart the computer. Unable to delete the program so I can download the program again. Same message comes up.

firefox message comes up every time I try to get on the interner with firefox. I received an email about two weeks ago from Mozilla advising me to download the updated firefox program. I have not been able to get to firefox since. I have tried to delete mozilla from my computer and get the message that I must reboot the system. I get the same message when I try to get on the internet with firefox. STATEMENT IS "Your computer must be restarted to complete previous upgrade of Firefox."

Try to run the Firefox program once as Administrator (right-click firefox.exe: Run as Administrator).
If that doesn't solve the problem then remove the Firefox program folder (C:\Program Files\Mozilla Firefox\) to do a clean reinstall.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
Remove the Firefox program folder before installing that newly downloaded 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.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile 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.

Cannot open Firefox. Error Platform version 1.9.2.15 is not compatible with minVersion =1.9.2.16 maxVersion =1.9.2.16

Received an update yesterday that turned off Norton before installing itself. Now cannot open Firefox. Get error message.

This issue can happen if the updater wasn't able to update all the files.
Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
* Firefox 4.0: http://www.mozilla.com/firefox/all.html
* 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.

I cannot open firefox. I am told that it has crashed. I've sent reports but haven't heard back.

I cannot open firefox in safe mode. I have to use internet explorer.

Have you been using Windows System Restore ? that can cause Firefox problems and sometimes problems similar to yours. (Bug702045)
I wonder if more than just the profile may be corrupted in such circumstances? '''If '''the new profile does not work '''try a clean reinstall''' of Firefox 8

Cannot open firefox in more than one window

I cannot open Firefox in more than one window. I deleted and reinstalled the latest version but this did not help. I was able to open Firefox in multiple windows prior to installing an update of Avast. Don't think it should have an effect on Firefox.
Downloaded Seamonkey and have no problem with multiple windows.

Anyone?

I cannot open firefox from my desktop or start menu

I cannot open firefox from my desktop or start menu. this happened last night. IE will open and functions properly. I have the latest version of firefox installed. thank you

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

Please help, I cannot open Firefox at all! crash ID: cf9fa02c-586d-4033-999b-a7a242110501 and Signature: mcffplg.dll@0x1cb20

It happened a few weeks a go, I have re-installed the Firefox but still didn't work. I can only open Internet Explorer. I cannot open Firefox and Google Chrome at all!. I am using windows 7.
Please help, I want my Firefox back...

The crash is reporting a problem with the McAfee Site Advisor (mcffplg.dll), try uninstalling the McAfee Site Advisor and see if you can then start Firefox.

I cannot open any documents in Indesign after downloading Yosemite. Says I need Java 6. I have Java 8 and still doesn't work. Please suggest.

It may seem strange indeed, but yes, you have to ALSO install the older version 6 for Apple's system; other applications will use your Java (which I believe is now even 9) and others will use that version 6.
Download directly from Apple here:

July 18,2011 AOL toolbar update install. I cannot open Firefox to uninstall the update or the toolbar because everytime I open Firefox it freezes and jams up. I have to shut down my computer as it will not even respond to force quit command

July 18,2011 AOL toolbar update install. I cannot open Firefox to uninstall the update or the toolbar because everytime I open Firefox it freezes and jams up. I have to shut down my computer as it will not even respond to force quit command. I cannot read my mail (aol) or access my bookmarks all for work.

Try the Firefox SafeMode. 
''A troubleshooting mode, which disables most Add-ons.'' 
''(If you're not using it, switch to the Default Theme.)''
# You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
# Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. 
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
You should be able to uninstall that AOL toolbar extension while running in the Firefox SafeMode.

Cannot open apps iPhoto and Aperture after updates

Cannot open apps iPhoto and Aperture after updates. I'm operating ML on mbpro. Now apps will not open. Simply that.

Not simple, if as ML implies you are running Mountain Lion! If you only mean Lion, then it would be useful for you to open another User Account, and as that User test to see if either app will launch?

I suddenly cannot open Firefox

I turned on my windows vista computer and it would not start properly so it resolved the problems, then started up.
Since then i cannot open Firefox, i click on the icon and nothing opens. I have tried shutting down/restarting but still i does not work.

There is a problem fairly soon in the process if profile manager will not start.
You could try in Firefox's [[safe-mode]] next you could try in Windows safemode by using the F8 key.
From what you say I am wondering if you have done a Windows restore of some form and recreated Firefox that way. Firefox does not always restore properly from Windows. You may be looking at re-installing Firefox.
If you consider re-installing do NOT take any options from Windows or Firefox that offers to delete personal settings because that will destroy things like passwords and bookmarks.

Cannot open firefox on email (AT&T yahoo) icon since updating to v8

Ever since I updated to the new version of Firefox I cannot open Firefox when I click my AT&T yahoo icon. I get an orange screen and it says Mozilla Firefox in the upper left corner. If I click in the left corner it says "not responding." This also happens when I click on the Firefox icon. The only way I have been able to get into Firefox is to right click on the Firefox icon and select "open outside BufferZone." BufferZone is a security program Kim Komando recommended. I did not have this problem until I updated. What can I do to fix this?
