I cannot start firefox with message your firefox profile cannot be loaded. It may be missing or inaccessible

i cannot start Firefox with message "YOUR FIREFOX PROFILE CANNOT BE LOADED. IT MAY BE MISSING OR INACCESSIBLE"

This is usually caused by a problem with the profiles.ini file and the profile marked as Default=1 in this file is no longer present on the hard drive.
*Windows: %AppData%\Mozilla\Firefox\ C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
*Linux: ~/.mozilla/firefox/
*Mac: ~/Library/Application Support/Firefox/
You can use one of these to make Firefox create a new default profile or reuse an existing profile:
*Delete the profiles.ini file to force Firefox to create a new default profile
*Use the Profile Manager to create a new profile Use "Choose Folder" when you create a new profile to select the location of a lost profile and recover this profile

Your firefox profile cannot be loaded. it may be missing or inaccessible. Vista

Vista. I tried uninstall and reinstall 3.6.3 and 4 beta 7 with reboot in between.
When I try to start FF 4 beta 7, I still get the message "your firefox profile cannot be loaded. it may be missing or inaccessible"

Use a specific [[Managing profiles|profile]] to test Firefox 4.0b7 and keep your current profile for Firefox 3.6.
Moreover, you use an out-of-date version of Firefox 3.6, [[Updating Firefox|update Firefox 3.6]].

When I download and try to install Thunderbird I get the message "Your Thunderbird profile cannot be loaded, it may be missing or inaccessible".

Because of a virus, I redownloaded Thunderbird 24.4.0 and it completed until trying to open Thunderbird when I get the message "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." I know the profile exists in a "recovered files" folder. I've tried to move it to the current Thunderbird folder but get the same message. I've tried to follow a Mozillazine article but it's too complicated. Is there any online help, such as chat or phone?

I think I have finally figured out how to reply to you. Even though your email says to reply to [email protected], that just goes into dead space.
So to answer your question, the profiles.ini file has in it:
<pre><nowiki>{General}
StartWithLastProfile=1
{Profile0}
Name=default
IsRelative=1
Path=Profiles/ghdigdus.default</nowiki></pre>
Also, I want to mention that there is a Thunderbird folder in C:\ just above the Users folder. It has two profiles in it, one of which is the e00qmtzd.default folder.
Are we getting closer to solving this problem?

I lost Firefox for no apparent reason. I deleted the program and attempted to reinstall and download. Received an error message that read "Your firefox profile cannot be loaded. It may be missing or inaccessible." At the same time, I lost Picasa and all my photos. When I tried to reinstall Picasa, I received the same message about Firefox. Can someone please help. It's driving me nuts.

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
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.

Firefox profile cannot be loaded it may be missing or inaccessible WINDOWS 8

I have a Windows 8 OS running on a PC. I have been using Firefox as my browser for several months. Suddenly, when I try to load Firefox, I get an error message, "Your Firefox profile cannot be loaded. It may be missing or inaccessible." I have uninstalled and reinstalled Firefox version 21.0 twice, and still get the same error message. How do I get to the profile.ini file using Windows 8, and what am I supposed to do when I ever get there?

There are a few steps to try.
First, try resetting Firefox:
https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems
If this doesn’t solve the problem, trying using the Firefox Profile Manager to remove your old profile and create a new one manually:
https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
If this still doesn’t work, try deleting the profile.ini file to force Firefox to create a new default profile:
* Make sure that Firefox is closed
* Press Windows key+R to open the Run box
* Type: %APPDATA%\Mozilla\Firefox
* Click “OK”
* Delete the file called “profile.ini”
* Run Firefox again

Uninstalled Firefox & deleted profile folder. Installed new Firefox but box pops up "Your Firefox profile cannot be loaded It may be missing or inaccessible."

I can't reinstall firefox. I deleted the profile folder and uninstalled firefox in hopes of clearing up the cookies from some problems I was having accessing my school course through a website. It seems to be downloaded but won't open up because the profile is missing. Help is appreciated thanks!

If you delete the Firefox profile folder, but leave the profiles.ini file then Firefox will try to access the folder that is marked as "Default=1" in the profiles.ini file and that will cause this error message.
*Mac: ~/Library/Application Support/Firefox/
In Mac OS X v10.7 and later, the ~/Library folder is a hidden folder.
*http://kb.mozillazine.org/Show_hidden_files_and_folders#Mac_OS_X
You do not have to delete the Firefox profile folder if there is a problem with the cookies.
You would only have to delete the cookies.sqlite file that stores the cookies in case clearing the cookies in the normal way isn't working.
You can try these steps in case of issues with web pages:
You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
*Hold down the Shift key and left-click the Reload button
*Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
*Press "Command + Shift + R" (Mac)
Clear the cache and remove cookies only from websites that cause problems.
"Clear the Cache":
*Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window

When I try to open firefox, the message,"Your Firefox profile cannot be loaded. It may be missing or inaccessible." How do I fix this on my pc?

I was trying to update firefox and it crashed and now....no more firefox

Hello,
you can solve this problem by going to your Applications Setting in Android ( Settings - Applications ), Select FIrefox and there you remove all datas.
it will delete the profile.
Then you'll just have to open Firefox.

Your Firefox profile cannot be loaded. It may be missing or inaccessible... Help!?

One moment I was able to use Firefox just fine and the next, I'm getting a pop up message:
Title: Missing Profile:
Message: Your Firefox profile cannot be loaded. it may be missing or inaccessible.
I cannot open firefox at all and I'm at a loss of what to do. I can't even troubleshoot firefox because firefox is trying to open but it can't.
What I believe happened was that firefox was in the middle of updating/trying to open in safe mode and somehow got interrupted. I have been looking around online trying to find a solution and so far I've been coming up short and any help would be appreciated!
I have Windows 7.
Thanks!

After a new install with old TBird uninstalled."Your Thunderbird profile cannot be loaded. It may be missing or inaccessible" Should have created a NEW profile?

My Windows 7 Ultimate computer received an unauthorized Windows overnight update followed by error messages. Bless Microsoft. To compound the problem there were NO restore dates found and no recent backups. I lost about the last entire year of data including all my many downloads and recent documents, etc.
Like another user, I also had more than a year of Thunderbird emails in my inbox and many other folders. Important to me. Now TBird won't open...at all... and gives me an error message: "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." OK. So I uninstalled it and REINSTALLED IT, more than once, and still get this same error message after a supposedly successful installation. The error message and then TBird fails to open. Shouldn't it create a new profile with the new install?

No. It's looking for, and finding, profiles.ini but can't find the profile in the location stored in profiles.ini.
Deleting (or moving or renaming) profiles.ini should indeed force it to generate a new profile.
Do these help?

I keep getting a "Your Firefox profile cannot be loaded. It may be missing or inaccessible" message and firefox does not open. WHat is wrong and how do I fix?

I uninstalled Firefox from my computer, then I reinstalled it and tried to run it, but this message appeared, "Your Firefox profile cannot be loaded. It may be missing or inaccessible" and Firefox does not open at all.

hello davidrusso71, press windows-key+R on your computer and open ''%appdata%\Mozilla\'' - an explorer window should come up, in there rename the folder labelled "Firefox" to something like oldFirefox. on the next start of firefox this should lead to a new profile being created...
you might want to import some of your old data into the new profile afterwards: [[Recovering important data from an old profile]]
