I cannot open Firefox at all... receive "Profile Missing" -- what next?

MAC desktop being used. When I click on my Firefox app it looks and looks then brings up a window: Profile Missing.
Obviously, I cannot do much without opening Firefox.
What do I do next?

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

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 Firefox at all!!!

I really hope someone can help me with this it's driving me crazy to have to use Internet Explorer.
All of a sudden yesterday when I booted the laptop up, I have been unable to open Firefox. I click on it, and just nothing happens whatsoever. I've tried EVERYTHING, reinstalling, running in Safe Mode (still nothing happens) and literally nothing works.
What can I do? My laptop is a 1525 Inspiron running on Windows Vista.
Thanks, Lisa

SInce the latest update Firefox has crashed continually for about two weeks now. Continually means at least 10 times a day. Now it does not open at all and I get this message when launching Firefox:

The new version 4.0 doesn't work wiith my Power PC, i found out too late, and now cannot open Firefox at all -- where might i download 3.6, please?

I am willing to forgive Firefox for not warning me about this -- but surely, you '''could''' make it easier for me to find 3.6 on your website. It is now gone from my system and i am in limbo -- probably with 1000s of other unhappy users.
Back to Safari --

You can get Firefox 3.6.16 from http://www.mozilla.com/en-US/firefox/all-older.html
There is a third party version of Firefox 4 that runs on OS X 10.4 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox

I can't load firefox because it says "Profile Missing- Your Firefox profile cannot be loaded. It may be missing or inaccessible." Can't delete either. Help?

I have a Mac and I can't open firefox because it says "Profile Missing-Your Firefox profile cannot be loaded. It may be missing or inaccessible." Then I tried to delete it by moving it to trash and it says it cannot be moved to the trash.

I cannot launch Firefox (suddenly) nor can I open Profile Manager, what next?

Windows 7, 64 bit. Experienced some Windows updates but I restored to prior to the updates and still cannot open Firefox. Can open Safari and IE.

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.

Firefox 4 won't open because it says it is not supported by the current architecture. Now I cannot use Firefox at all.

I followed the advice and instructions to download Firefox 4 and once I moved it to the applications folder, a slash went through the icon and now it tells me that I cannot open Firefox because it is not supported by the architecture. Don't know what to do next.

I suspect you need more expert help but here are a few things you can try.
If you can't open Firefox(double click on Firefox desktop icon) try Safe Mode - Hold down the Shift Key as you double click on the icon>don't check anything on the page that opens>continue. If Firefox opens and works in this safe mode go to Add-ons> Extensions and look for "Ask". Then look at Add-ons >Plug-ins and again look for "Ask" . Remove, delete,disable any Asks. If you do remove any, close Firefox. And try again in Normal Mode.
The Ask website has detailed instructions for removal but you need to find it on your computer and have your computer in working order.
If there is no sign of Ask and Firefox is working well in Safe Mode you should work your way through this -
https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
Eventually you might need to grapple with About:Config and even your Windows Registry but I would recommend a complete uninstall and re-install before that. Unfortunately that often doesn't work.
That all sounds very daunting but taken step-by-step you might get lucky early.

Firxfox installed (without me agreeing!) and update and since then I cannot open it at all. RE-installation didn't help. I urgently need Firefox up and running with my bookmarks intact. Thank you

As mentioned above, when I opened Firefox this morning it installed automatically an update w/o me agreeing and I don't know what was isntalled. Since then I cannot open Firefox. Mozilla Crash Reporter opens and thell me Firefox had a problem and crashed. "We'll try to restore your tabs and windows when it restarts.
To help us diagnose and fix the problem, you can send us a crash report."
I press restart Firefox but I always just get the same message. I uninstalled it and downloaded it again, nothing is changing. I urgentlyu need to use the bookmarks as I don't have them in Explorer which I have to use now.
Thank you

You need "sysinternal's process explorer", it is free and can replace the Microsoft process explorer, that you get by "CTRL+ALT+DELETE". Either program will allow you to kill the instances of FF that didn't die as they should have, when you closed them. Sysinternal is easier to use, it is a graphic display with many options. Do not push "CTRL+ALT+DELETE" twice unless you want to reboot, that is its default behaviour under Microsoft.

I cannot open Firefox so decided to try and uninstall and reinstall, when the uninstall or install wizard starts I keep getting "Firefox must be closed to proceed, please close Firefox to continue" but i do not have Firefox open at all.

Originally I was having a problem with Firefox locking up everytime I went to a website and tried to X out of it, there would be no response. Or the little box would come up with the question on whether i wanted to Quit or close tabs, I would make my choice but nothing would happen. Then yesterday I couldnt open Firefox at all, so I tried to uninstall and also reinstall but keep getting the error message "Firefox must be closed to proceed, please close Firefox" But i do not have it running anywhere, it does show in my downloaded programes, but I cant do anything with it. I am running Windows 7 on a Dell Inspiron

Hopefully this support article is what you need:

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.

When I try to open Firefox 3.6.17 I get an error message which says............. Platform version 1.9.2.17 is not compatible with mini version =1.9.2.21 Max version =1.9.2.21 and I cannot open Firefox.

When I tried to download the new version of firefox I get an error message that says "you computer must be restarted to complete an earlier upgrade" when I restart it says the same thing. I cannot use firefox at all at the moment.

I cannot use firefox at all at the moment. When I try to uninstall in the control panel, the same message pops up.

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded

Hi, InsaneCharlie.
Thanks for the question. I see you have uninstalled iTunes and want this program back. Start with completely uninstalling iTunes if present and all of it's components in the order specified in the article below. Once this is done, download and install iTunes. If none of your data was modified in the iTunes media folder, then your data should be present upon installation.

If you receive any errors when uninstalling any components of iTunes, try the steps in the article below for each component that gives you an error.
