I deleted my user profile by accident now I can't open firefox, what do I do?

Basically I deleted the file in the Library/Application Support/Mozilla/Profiles folder and all other mozilla folders I could find thinking that I was going to completely remove and reinstall firefox on my computer (I was having issues with add-ons and wanted to see if I could un/reinstall ff to resolve the problem). Anyway I reinstalled ff and now when I try to open it, a message pops up that says "A copy of Firefox is already open. only one copy os Firefox can be open at a time." How do I get firefox back?

-> Go to Mozilla Firefox folder in Program Files -> right-click '''firefox.exe''' -> go to '''Send to '''and click '''Desktop (Create shortcut)'''
-> Close Program Files folder -> Firefox shortcut will be on your Desktop now
Check and tell if its working.

I updated and now I can not open firefox

I installed the damn update you sent and now I can't get Firefox open

What exactly happens when you double click the Firefox icon? Does it display any kind of error-message? And could you please start Firefox in [[Safe Mode]] to make sure that no customization is responsible for the issue?

Downloaded updated Firefox and now I can't open Firefox at all, it keeps telling me to reboot. I have rebooted 5 times. Any ideas?

I had Firebox 3.6 Just downloaded the updated Firefox 9.0. Everything seemed to run fine in the intallation but I can not open the browser. It keeps prompting me to reboot to finish the installation. I have rebooted and shut down completely. It continues to prompt me to reboot. I really need the brower to open, I'm going to lose all my bookmarks and I hate Internet Explorer.

Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0: http://www.mozilla.com/en-US/firefox/all.html
* 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.

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 updated mozillo firfox and now i can not open firefox. i have tried everything, uninstall and intall, tried to read other peopl's recommendation, nothing work

I updated firefox 27.0.1(x86.en-US) two days ago and now it is not opening. please help me, it is frustrating. I have been using firefox for a long time and I have saved a lot. can you please help me. I have checked under firewall and Mozilla firfox is not blocked. I have read every recommendation I could get to fix the problem but not working. I have windows 7

One of the suggestions probably was to try starting Firefox in its Safe Mode by holding down the shift key when starting Firefox. (This doesn't work if Firefox is still running hidden in memory.)
In the small dialog that should appear, click "Start in Safe Mode" (''not'' Reset)
Any luck?
Also, I will message you a link to download Firefox 27.0, in case the problem is unique to Firefox 27.0.1.

I downloaded Firefox 4 but my laptop cannot open Firefox 4. I want my old Firefox so I don't lose my bookmarks, etc. Now I can't open Firefox at all.

As propmted by firefox, I downloaded Firefox 4 for my Mac. However, my Mac is not able to open this version of Firefox. I bought the computer in 2007 and have not had it updated since. I replaced my old firefox so now I cannot open the browser at all. Can I download an old version of firefox? Are my bookmarks lost?

Firefox 4 requires at least OS X 10.5. You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
When you re-install Firefox 3.6 it will use your existing bookmarks and other user data.

I just updated firefox to the lastest version. I have a network in which we access the server with remote desktop. Now I can only open firefox on one of the remote terminals or the server. I need to be able to use firefox on all of the terminals.

I get an error message that says an instance of mozilla firefox is already running, please close it to continue.
The question already explains the situation. I need all three terminals to use firefox concurrently.
Did not have this problem with the previous version.

That happens if all instances use the same profile folder.
Only one instance can use a specific profile.

I have one site in my browsing history that won't erase for some reason, and it's been crashing Firefox every time I try to erase it. I changed my security preferences to clear history before each session, and now I can't open Firefox at all. Help.

The site in question was the homepage for Air BnB (http://www.airbnb.com/). It's never given me problems before, and didn't even after this particular instance. I would like to continue using Firefox, but it ill no longer open, I'm assuming because it gets stuck trying to clear the history (as per my changed preferences).
Is there a way to uninstall the program without losing my bookmarks?
Is there a way to manually clear this problem with my history outside the program?

Have you looked for the previous render files? Show contents of your library and see if there are any files in the Render folder from last night.

A window asked me to close firefox.exe so it could do something (AVG I think). Now, I can't open Firefox at all even after uninstalling and reinstalling.

When I took my laptop, which is running in XP, to get rid of a
number of trojans, etc, the computer tech put AVG on it. Since
then, I have been getting random notices from AVG. I got a
notice and clicked it before thoroughly reading it, assuming it
was another one of these. It said something about closing
Firefox, and I thought it needed to close Firefox so it could
scan something. Ever since, I click on the shortcut or the file
itself to no avail. Nothing happens. I've even tried
uninstalling and reinstalling. Have I unknowingly changed my
administrative settings?

Annette,
#In the menu bar, at the top of the Firefox window, Go to Tools -> Add-ons -> Extensions.
# Locate ''each ''of the following extensions by name and click the disable button
#Restart Firefox as prompted and see if the undesired toolbar has been removed.
#The extensions to disable are: '''Crawler Toolbar''', '''MP3 Rocket Toolbar''', '''MSN Toolbar''', '''Search Helper Extension'''
If you don't need some / all of those toolbars, consider leaving them disabled.
You can probably remove these toolbars permanently from Start -> Control Panel -> Add/Remove Programs.

Started to clear browse history and now I can't open Firefox at all for the past four hours

I am on a MacBook Pro and recently was prompted to upgrade Firefox. Since the upgrade, I found surfing the internet harder as I frequently found Firefox...not crashing...but it would get stuck trying to open up or to open up a new page or site. I looked this up in Firefox support and found something called "hanging" and this sounded like what I was experiencing. Looking through I tried finding the various solutions. Nothing helped. I did try to clear the browsing history. Each time I tried that, it locked up with the spinning thinking wheel. Then, I tried resetting the preferences to clear on exit and then exited. Ever since then, I cannot get Firefox to launch to the internet at all. I get "not responsive" on a right-click. Please help. I love my Firefox. - Lynda

How To Properly Delete a User Profile on Windows 7 in a Domain environment

I have not been able to find an answer that matches the issue I'm facing. I had recently setup a laptop for a user and soon after, he was experiencing issues that I thought might be profile related. So, I did what always worked for me on prior versions of
Windows without any fuss or side affects.
Logged in under the local Administrator account, I went into: System Properties>User Profiles>Settings and removed the user profile from their. When I do that, I get an error message:
Profile Error
Profile not deleted completely. Error - A required privilege is not held by the client
Ok, no problem I think. I just need to delete the user's profile directory under the users folder right? So I do this and figure when I try to log in again as the user that a new profile will be created. However, this is not what happens exactly. I login
with the user credentials and it logs in successfully. However, I get a pop saying:
You have been logged on with a temporary profile
You cannot access your files and files created in this profile will be deleted when you log off. To fix this, log off and try logging on later.
Please see the event log for details or contact your system administrator
So my question is; why did the profile not delete completely after both deleting the user profile under System Properties and after deleting the actual profile directory? What did I miss and what is the proper method of deleting a user profile completely
without running into these other issues?

Hi Womprat,
According to your description, I understand that you want to delete user profile but display an error in Windows 7.
Please use other user (with administrator privileges) login this computer, then open Properties for Computer--->Advanced system setting--->Settings for User Profiles, then select the profile you want to delete.
