Firefox won't open and neither will Profile Manager.

I running Windows 7 Professional. So about two weeks ago I had suddenly was unable to open Firefox and since then have been trying to solve it myself to no avail. the Firefox process opens in the task-manager, however, the browser window does not appear. When trying to open Firefox again, another process opens and the same thing happens. Processes just keep opening and that's it. I have tried the Profile manager but it only opened once and I have been unable to get it to open again. Every once in a while Firefox actually opens when I launch it, but when I close it to see if it works again it does not. Firefox does open in Safe-mode with Networking with no problems consecutively. While it was in safe-mode I ran a full system scan with Nortan Antivirus and cleared about thirty threats but after the restart Firefox still won't open, only processes. I have tried deleting Mozilla from the x86 path and cleared My local and roaming Mozilla appdata, then re installed with 34.0.5. I have tried opening Firefox in safe mode but it won't open at all, only the process again.

<blockquote>
It is possible that your security software (firewall, anti-virus) 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 and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.

My firewall has been off for ages. And I did a check with Nortan. It didn't help.
EDIT: Turns out I was just being lazy I guess. I had read this post before on another user and it didn't work for him so I didn't try it. AWD did clean a lot of stuff but didn't work, Malwarebytes however cleaned more things and suddenly Firefox opens each time I try. Not sure if it is permanent yet.

Firefox no longer opens, and neither does Profile Manager

So yesterday some website from a Google search (Kilauea photos search string) did something wacky, and now Firefox 4.0.1 will not start. Safe mode doesn't start. Profile Manager won't start either. Uninstalling Firefox, removing Firefox's folder from Program Files, running a registry cleaner to clean up Firefox leftovers, running a full MS Security Essentials scan which did find some nasty trojans, and then reinstalling Firefox only works for the initial session. A rerun of Security Essentials, and a run with IObit's Malware Fighter find nothing. Once I close and restart, same as in the beginning. Internet Explorer 8 and the 3.7a5pre Minefield version of Firefox seem to run normally other than Minefield fails to remember passwords even though it's checked. Any ideas on what to try?

I tried Firefox 3.7. I tried Firefox 5 beta. Same thing kept happening. Searches for similar situations just wasn't turning up a viable solution. I may have finally figured it out though. What to do when in doubt? Start doing searches on the processes running in Task Manager. All antivirus programs I have installed have FAILED to recognize this executable as malicious. Look for an executable in your Task Manager that says hdmclean.exe. It will be under ~\users\***\appdata\local. It must be a variant (at least in name) of hddclean.exe. As soon as I terminated the process I was able to launch Firefox 5 beta. I went ahead and deleted the damn bastard, and then rebooted. Seems to have solved the problem as far as I can tell.

Itunes won't open and neither will microsoft internet explorer :I

Hi
My Itunes hasn't been able to open for months, the first time it happened was about the time my Internet explorer stopped working for no reason and my msn messenger won't connect either. Could these be linked I have a had a few I.T. keen people look at it with no solution... I have tried removing and reinstalling Itunes and msn Messenger but nothing has worked. When I click on it, it just won't open... any ideas?

okay.
some preliminary questions aimed at narrowing in on
possible culprits.
(1) do you have Norton Internet Security 2005
installed on the PC?
(2) try launching your QuickTime. does it:
(a) launch perfectly fine?
(b) fail to launch with an error message? (if so,
what does it say?)
(c) exhibit other peculiar behavior? (if so, could
you describe it for us?)
(3) reboot the PC. bring up your Task Manager, and
click on the "Processes" tab. now try to launch
itunes again.
does an "itunes.exe" process appear in the Processes
tab? if so, does it persist in there or does it
disappear after a few seconds?
hey, i recently been having troubles with opening iTunes
i thought you could help because you suggested something that is causing me trouble (number 1: Norton 2005)
i click to open iTunes.exe but nothing happens. the process appears in the Task manager, but i cannot terminate it. And upon opening, my Norton session manager ends with an error
can you help me?

Trial won't open and neither will my account

I recently downloaded the trial for photoshop but it refuses to open. I had no probelms with the download but every time I try opening the program its tells me that I need to renew my subscription, and this is based on the adobe account of the previous laptop owner. It does give me the option to sign in to my account, but everytime I sign in it redirects me to a serial number screen. I've deleted all the previous adobe programs under the previous owner's account but that did not help at all, it still tells me the same thing. I am obviously missing something here. Any help would be much appreciated.

This won't work. You cannot have a trial and the same product serialized at the same time. Even flushing out the activation data as explained here won't help, as the encrypted activation keys are stil lstored on your system. Sorry, but short of reinstalling your operating system wit ha full format of the drive there is no realistic way that this will ever work.

Tried to use Restore to return to pre-Firefox4 but now Firefox won't open and won't uninstall.

After trying to maneuver the new Firefox 4.0 for a while and giving up, I wanted to go back to the 3.6.1.6 version. I used the Restore feature to try to go back to the pre-Firefox 4.0 dowload. Since then, Firefox won't open. I have tried to uninstall Firefox 3.6.1.6, which is listed in my installed programs in the Control Panel, but it doesn't do anything. At this point I don't know what to do. I want to re-instate the 3.6.1.6 version on my computer. Thanks.

You're in a bit of a pickle here because you can't use System Restore to revert to 3.6.16. You probably now have version 1.9.2.x which is in part, files which were not removed when you installed FF4
What you can try and do is use System Resore to undo the last restoration which should take you back to 4.0 again. If that fails, see this article: http://kb.mozillazine.org/Uninstalling_firefox
If the undo restoration is successful, do the following to revert to 3.6.16
Go to [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.16] and download it to the desktop. If necessary, download the file with IE8 and choose to save it to your desktop when you see the prompt.
Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
Then reboot and delete the folder called '''Mozilla Firefox''' at this location: ''C:\Program Files\Mozilla Firefox''
Finally run the installation file you downloaded to the desktop earlier.
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.

I'm using a mac, my profile can't be found, firefox won't open, and I don't have an application support file for firefox.

I tried to reset firefox because it was running slowly, in the middle of it "cleaning up" my old files something happened and firefox closed. I tried to reopen it and it kept coming up with an error message about my profile not being able to be found etc. I tried looking for solutions but couldn't find one that I could follow. Please help.

Follow the instructions to create a new profile. Then test it.
After, you can move your files from the old profile to the new one.

Firefox won't open and won't uninstall so I can re-install and start anew. HELP!

I'm on a Dell laptop with Windows Vista using the latest version of Mozilla Firefox. My son was playing a game online (addicting games website I think) and the whole game screen didn't show up, he had to scroll. I went to the top of the page and right clicked and closed the address bar and menu bar so they weren't in the way. I've done this in the past and it worked fine. Not this time! When I went back to put those bars back on I couldn't do it. I had no address bar, no forward, back, refresh and home buttons, no file, edit, view buttons etc. I looked in my internet settings and all over the place and couldn't figure out how to replace those bars. I uninstalled Firefox and reinstalled it but those bars still were not there. I did this again after deleting browsing history (cookies and all) in case this problem was saved in my preferences. Still, no bars or buttons. I tried to uninstall again but now it won't even uninstall! It stubornly stays right there! It also won't even open now! I click on the icon and it sits. I right click the icon and hit open and it sits. I'm dead in the water. I can't even sign in to Pogo anymore because IE crashes everytime. I hate IE.....HELP!

Right... Back to square one.
- Open Internet Explorer, go to "www.mozilla.com" and download the installer for Firefox 3.6.12 and save it to your desktop.
- To uninstall Firefox, first make sure no "firefox.exe" processes are running on your machine: Open the task manager (invoke it by pressing ctrl-alt-del and choosing the appropriate option), click on the "Processes" tab, click on the heading "Name" to sort all running processes by name.
Scroll down the list and right-click on the first "firefox.exe" process picking the "Kill process" option. If there's more than one of them, repeat for all instances of "firefox.exe".
- Now go to the directory C:\Program Files\Mozilla Firefox\uninstall and double-click "helper.exe". This should uninstall Firefox completely.
- Now we're in for the hard part: Go to C:\Dokuments and Settings\[Your User Name]\Application Data\Mozilla\Firefox\Profiles. That's where your profile resides. Unless you're using the Profile Manager, chances are you're seeing just one directory "[random string],default". (In my case it's called "4sr92zjz.default", f. ex.).
If you got any bookmarks you'd like to keep, open this folder, find the file "places.sqlite" and move it to your desktop.
Now delete the entire contents of your profile folder--you'll need to configure firefox anew. Do keep this window open, you'll need it again in a few moments.
Go to your desktop, run the installer, start Firefox once, close it again and move your "places.sqlite" file from your desktop to your profile folder.
Now double-click Firefox and reconfigure it according to your preferences.
N.B.: Do get "MozBackup". With this application you're able to save and restore a working Firefox profile--for your next mishap ;-)

Firefox won't open and the steps in tutorial didn't help nor did uninstalling and re-installing

Hi,
I have been thru the tutorial and none of the steps solved the problem I am having with firefox. I just installed it on a new computer and it won't open. It says that it cannot run until process is ended or computer is restarted. Restarting and ending the process don't seem to help. The other tutorial step of deleting the lock file doesn't work either as I could not find a lock file.

Sometimes firefox won't open and I have to 'end process', and others it won't let me search in the searchbar, or open a new window. What's going on?

Sometimes when I close firefox, it won't open again. I have to 'end process'. Other times it will not open a new window until I 'end process'. Sometimes it even won't let me use the search bar until I 'end process'.

Do you have Restrictions turned on in Settings>General?

Firefox won't open and gives me an error that it is already open when it isn't.

Whenever Firefox crashes or I restart the computer, I get this message that I can't open a new browser because Firefox is already open.
I am using a MacBook Pro OS 10.6.7 and I have Firefox 5.0

I have the same problem when I'm trying to browse ringtones and stuff for my phone (browsing on my pc) on the site mytinyphone.com .. and when I click the "OK" button, it redirects the page that I am on to some other page, and when I click the back button in firefox to go back, it pops up and same thing happens.

Firefox won't open and i keep getting this error

when i click the firefox icon i get this error that says Your Firefox profile cannot be loaded. It may be missing or inaccessible.what dose it mean!? how can i save my internet!?

Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Firefox won't start; no error message; profile manager also won't start. What can I do?

Suddenly, firefox won't start. I get no error message--it just won't open. System restore to a month before the problem did not help.
From the suggestions on this page: http://support.mozilla.com/en-US/kb/Firefox%20will%20not%20start... I did not recently install add-ons or clean the registry, so I think it may be a profile problem. But profile manager will not open--only a tiny window with a white rectangle and no text.
I would like to not lose all my bookmarks. And I would like to continue using Firefox.
What can I do?

dmcritchie, thank you for your reply!
Before I received your response, I tried something that seems to have worked. I used Chrome to go to the Firefox website and downloaded Firefox (without uninstalling it first) and went through the installation process again. For some reason, this worked, even though I already had the latest version of Firefox, and I can now open Firefox successfully.
If it stops working again, I will try your suggestion. In the meantime, thank you much!

Firefox won't open, and doesn't show up in the task manager.

I have clicked on all the icons available, but none will open the browser.
I do not get an error message.
It does not show up on th task manager.
I have restarted my computer several times but no result.

Well we thought it may be something to do with the way FCP writes all the Sequences that it may have something to do with it, but we have hours and hours of tape that we are editing and we need to work on small sections at a time and we are testing different flows of the edits and save as needs to be used. If FCP can’t handle save as, why do they put it in the program? We are pushing for an hour of video and we are now ready to give up on the HD and just convert it to DV, because of FCP 5.1.4 crashing or just being slow on the G5. The DV stuff is quick and it may be best for us anyway. This thing needs to look rough.
I started with FCP4 and my partner had experience with FCP2 and then we both are now using 5.1.4 and it is doing strange things and he said he was use to doing commercials on FCP2 on a laptop and it was easy…they have so many options and settings it’s no where near the same as FCP2, but we will learn what we need. I know some of it is a learning curve on our end, but as we upgraded our programs the last time, all Apple sent was disk and the only manuals I have are 4.5. and I need info on how best to go from FCP 5.1.4 to compressor then to DVD Studio Pro 4 so we can see how our edits look on DVD. The help menu is not the best I’ve seen and that’s why I am looking to the group.
Thanks,
Mark

My voicemails won't play and neither will my music

I can't get my voicemails to play - all it does where the play button is is having a spinning circle - a couple times a popup as come up and said unable to connect. Also, my music (from itunes downloaded to my phone) hasn't play for a month since I got the phone. I have the 4s - got it brand new when it came out. I am so frustrated! Does anyone have any answers? PLEASSSEEE!!

well I was always using the visual mail I guess it's called - where you go to phone then voicemail and tap the one you want to play - I ended up just calling myself and entering my password and it played my voicemails for me - then when I went back to the visual one - they were working again - not sure what happened. Also, I found this here on the apple site:
Follow these steps to troubleshoot issues with accessing voicemail on your iPhone:
Use iTunes to update your iPhone to the latest version of iOS.
Make sure you have good cellular network connection. You can verify whether you can make and receive calls.
Try dialing your phone number from your iPhone to make sure your voice mailbox is set up properly.
Reset your network settings by tapping Settings > General > Reset > Reset Network Settings.
Contact your carrier if:
You still cannot access voicemail
You experience difficulties with voicemail while traveling abroad
You are unable to reset or change your voicemail password
I did not do this yet - so I do not know if it will work - but I guess it's worth a try! let me know! Good luck!
