I am unable to open Firefox whenever I want to go online
This morning I tried to open Mozilla Firefox to go online like I always do, but it didn't open. I tried several more times and even tried restarting my computer, but it never worked. I even tried deleting it and re-installing/downloading it, but then it never showed up in the list of my Programs. Now I am online via Internet Explorer, but I much prefer Firefox. I tried opening Task Manager and going under Processes to see if there is a 'Firefox.exe' that I could right-click to "end process", but there wasn't. I'm just concerned that I won't ever again be able to go onto the internet via Firefox. Please help. My laptop is a Gateway, and not even 1 year old yet.

I restarted my Firefox this morning and it automatically updated to version 9.0.1. Since that update, I am unable to open Firefox. When I try to open it (and this is on a Mac), it does not respond and freezes with a white screen, the tab says "connecting...," and there are no bookmarks or anything showing on the browser. It does not respond at all - I cannot even click into the navigation to change any of the preferences. Please, someone help! Not having Firefox is killing me!
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, 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 and the updater process.

Unable to open firefox - get message that " a copy is already open and only one copy can be open at a time. I have dragged the app to the waste basket and downloaded another firefox app. However same result". I have a IMAC , V.10.6.3.
I get above message when I click on the firefox icon.This worked, I used the method described in this link http://forums.mozillazine.org/viewtopic.php?t=365156, and opened the Mozilla profile screen with the terminal on my mac, using the language given in the links. Then I duplicated my original profile to save the bookmarks, etc. Put them in a folder listed Duplicate profile with the date. With the open profile screen, I deleted my original profile, created new profile folder and then a new profile. Note that profile cannot be created in the system library, it must be created on the disc, because the library will not allow writing into it. After I created my new profile folder, I dragged all my old information into it, and it worked. Firefox closed and the error disappeared. You must be VERY careful to make sure Firefox is closed anytime you are doing anything with the profile folders. I think that is what caused my original problem.

Unable to open firefox. profile missing?
i was tring to down load firefox. after i down loaded it said unable to open profile missing.
See:
*https://support.mozilla.com/kb/Firefox+is+already+running+but+is+not+responding
*http://kb.mozillazine.org/Profile_in_use
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
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.

What happened first is Firefox was revving and using most of my CPU, ultimately "not responding" too easily and for too long, so I closed it in order to reopen it, but Firefox remained running in background (Task Mgr, Processes) after closing, continuing to use almost all my CPU, so I ended the process in Task Mgr.
When I went to re-open it, window opened and told me Firefox could not be opened because another "instance"(?) was still running, to close it or restart Windows. I couldn't close it because I already closed it AND ended the process, so I restarted Windows.
When I tried to open Firefox, I got the same pop-up. I think I restarted Windows one more time, and then uninstalled Firefox, except for my personal settings (in order to save the bookmarks, which I couldn't find in the Firefox folder in Program Files (only Favorites, which were not my bookmarks; I later wondered if they were part of the Firefox add-on "Add This" --??).
I then uninstalled Firefox and re-installed it. When I tried to start the newly re-installed program, I had the same pop-up telling me Firefox was already running and to close it or restart Windows.
I searched my computer folders for anything that might help, did a Search of the computer for "Firefox", and was given some Firefox folders and if they weren't from the new re-install, I deleted them. One thing I noticed was that the program folder did NOT have the program (Firefox.exe) icon to start Firefox.
I uninstalled Firefox and had to resort to using Internet Explorer, which I do NOT like. My rich library of bookmarks are who knows where.
I don't know if this is related, but in searching my computer's Administrative Services and Component Tools (and the like) hoping to find something that would help me fix Firefox, I inadvertently learned that "MMC could not create the snap-in. The snap-in might not have been installed correctly. Name: .NET Framework 1.1 Config."
Please help me get Firefox back and figure out what is going on in my computer that led to this. I am a basic user and not techno-computer saavy, so if anyone can help me with this, please give me step-by-step bonehead instructions.
Thank you so much for any help you can offer!Make sure that Firefox is set as the default browser.

I am unable to open firefox 4 properly without an error! HELP!
This is the message I now get everytime I try to open Firefox 4 broswer:
"Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features."
Now I have tried reinstalling it, disabling all the add-ons (including my Webroot), and scanning for every possible problem. I have 21 gig free space, so that's not it either. It does open and go to my home page, but it's jumbled and I can't do anything. Not even come to Mozilla's site. It just opens a tab and does nothing else.
I miss my Firefox already! Please does anyone know why this is happening and how I might fix it??Okay I just updated the Graphics driver like it suggested in my system details part. No change.

After opening Firefox, I was always able to in & out of it till I shut down my computer. Now, after opening Firefox, I go to another application then back to Firefox, I have to "Quit" Firefox and reopen. How can eliminate the back & forth of starting & quitting Firefox before I shutdown my computer?
uninstalled firefox ....deleted all files still remaining under mozilla firefox directory in program files ... to avoid having to reprogram all my settings, reisntall all addons as well .. I did not remove anything from mozilla firefox that is stored in either appdata or under the windows users directory (if any)
... the as suggested reinstalled the latest version of the firefox browser using the link you provided in the email ..; tested and several issues still remain present and unresolved ....
so please this is urgent or I will have to jump browsers and start using chrome .. because we work 14 hours a day 6 (sometimes 7) days a week, to get ready for the launch of our newest venture and we cannot lose that much days on browser related issues ... so please instead of putting me through week long step process .. of do this .. do that .. can you please actually look into the issue from your end .. I use firefox for so many, many years thta I deserve this kind of support .. thnx Robert -
Unable to open firefox 4 after download. Getting already running or not responding window.
Firefox 4 was working well at first and then would continually freeze. Now after uninstalling and reinstalling several times, including manually, I can not open firefox at all. I keep getting the "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." window. I have restarted my computer and looked on task manager and there is no firefox process running.

Unable to open firefox, dialogue box says program already open but not as far as I can see.
Recently when I log on to my pc and try to open Firefox, a dialogue box appears and tells me something like - firefox is already open, close firefox and try again. As I haven't opened firefox, I don't know what the dialogue box means. I went into task manager and the firefox program was not shown as open. I clicked the processes tab and deleted firefox from the list. I use Firefox 4 b9, this also happened when I had 4 b7. I uninstalled the former but no change. I reset system to earlier date, ran a virus check but all ok. I downloaded Firefox 3.6, then followed the upgrade for 4 b9 and all was ok until I was using my media player 2 days ago and tried to watch BBCiPlayer at the same time which is when the problem arose again. Also Firefox extremely slow to open. I managed to get online this time by going into History and clicking a website I used some time ago before all the above happened.
I am using IE to post this message on Firefox.
It has happened again. At 23:05 (UK time) I openedFirefox on the firefox site not IE. I opened my btinternet.com email account but at 23:41 the tab had not opened fully and still trying to load. I closed firefox and tried to open it again and here are the correct details of the dialogue box which appeared.
' (?) Firefox is already running. To open a new window, you must first close the existing Firefox proces, or restart your system'.
I cannon do a restart at present as the tv part of my pc is recording a movie so I will try again later.
Anyone out there that can help us please? Thank you. -
Unable to open Firefox (any version)
Been happily using Firefox ver 2 and recently ver 3 on my powerbook G4, OS X 10.4.11.
Recently Firefox would not open. I moved the application to the trash and went to download ver 3 again. Initially, could not mount the disc image: on download I got "verification failure". I then tried the same with ver 2, same error. This seems to have sorted itself out after 5 attempts, as I just downloaded the ver 3 application. However I still can't open firefox. There's no error message or indication as to why the app will not open.
Recent changes to my powerbook are I set file encryption (but that was long before I had this issue). Also of note, my preferences keep defaulting to Mac defaults i.e. the toolbar looses all my settings, itunes keeps losing my library and I just look miffed all the time.
Over 3 years, I've not had a single problem with this powerbook. When it rains it pours.Hi louiserb, and a warm welcome to the forums!
Generally, that bad img thing is either RAM, or problems with the HDD.
Failure of APPs to open is likely Permissions problems or incomlete installs.
At this point I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files!
Disconnect the USB cable from any UPS so the system doesn't shut down in the middle of the process.
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
Let us know where you are after that. -
I am ask everytime I try to open Firefox if I want to allow changes
Every time I try to open FireFox I am asked if I want to allow changes. It has always just opened up no problem. The first time this happen I responded allow but when it came up everything looked different. Will I always have to do this from here on out?
This error is usually caused because Firefox is set to run as Administrator.
Check that Firefox isn't set to run as Administrator.<br />
Right-click the Firefox desktop shortcut and choose "Properties".
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
* Privilege Level: "Run this program as Administrator" should not be selected
* "Run this program in compatibility mode for:" should not be selected
Also check the Properties of the firefox.exe program in the Firefox program folder (C:\Program Files\Mozilla Firefox\). -
i get a prompt to update firefox and i do then when i try to start firefox i am unable to. i have back-up my computer to previous date and the uninstall and re-install firefox to find the same prompt for updates from firefox and i cant ignore it so it is always there.
It's possible that you are 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 caused by one (or more than 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] (don't forget to select ''Disable all add-ons'' when you start safe mode). 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 themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone. -
FireFox can be opened but it is not usable since I am unable to view and access it on the screen/monitor.
I can open E, Google, with no problem only Firefox.It depends upon how you want to deal with the situation. Your old library file (library.itl) is corrupt. You can try either re-creating the library file or you can just start afresh.
If you want to start fresh, let it create a new library in a new folder.
We can go into details later.
If you want to re-create the library:
