Firefox won't open; tried all I found on this site; can't get in to disable add-ons.

Firefox will not open. Little wheel spins, then disappears. Nothing.
Re-started computer - several times.
Reinstalled Firefox. Nothing. Can't open in Admin. Can't open with double click or with right-click "Open".
Many fixes on this site suggest going to the Firefox button to disable add-ons - of which I have few - however since Firefox won't start, I can't try these options.
Can't get to my profile. (Have not changed my profile or add-ons for ages.)
This seems to have happened right after the most recent update.
I've read everything I can find on this website and other places, and can't make it work.
Can't find old Firefox on program list, thus can't uninstall old version - perhaps this occurred automatically with new Firefox download?.
Ran Spybot and deleted some adware and mal-ware. Still nothing. Ran Microsoft Security - nothing.
I'm running Windows 7.
I can't open the troubleshooting file offered below.
Firefox was working well until yesterday. Sigh. Can anyone help with this?

You can use one of these to start Firefox in Safe Mode:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled
*https://support.mozilla.org/kb/Safe+Mode
Create a new profile as a test to check if your current profile is causing the problems.
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 22.0: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*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.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.
*http://kb.mozillazine.org/Profile_folder_-_Firefox
*http://kb.mozillazine.org/Profile_backup
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Clean_reinstall
Do a malware check with some malware scanning programs on the Windows computer. 
Please scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

I have tried all of the above and still can't get my ipad to respond

Everything? Did you see the very last part about restoring the iPad and did you notice that there is another link in that step in case you cannot restore the iPad?
Symptoms
Your iPhone, iPad, or iPod touch may occasionally stop responding to buttons, switches, or touchscreen input and may exhibit one or more of the symptoms listed below.

I have lost my toolbar and task bar. I have tried all the sugestions on this site to no avail. I don't know how to try a system restore with out them.

I was enlarging pictures on Facebook to full screen. When i went to move on. All my tool bars and my task bar have disappeared. I have tried all the suggestions on this site to no avail. I don't know how to do a system restore without my task bar, and don't want to lose my book marks. Please help, i can't grt to my important favorite sites.

Can you launch a new window (Ctrl+n for a normal window, Ctrl+Shift+p for a private window) that has the usual complement of toolbars? If a new window also is missing bars, try using the View menu > Toolbars list to restore them. If the classic menu bar is not displayed, usually tapping the Alt key or the F10 key will show it temporarily.

Only wanted to give the youngest daughter the iPad to take to school.
Hope someone can help

Firefox won't open at all, and when I try to use the 'run' feature, it says the file has been moved, etc. I use Windows 8 and I can not lose my bookmarks. Help?

Firefox has been working great on my computer for months, and then all the sudden it wouldn't load any pages. So naturally I restarted my computer, but when it restarted Firefox wouldn't open at all. The icon glows for a bit like normal, then it fades and never actually opens. When I try to use the 'run' command, I get this error:
"C:\Program Files\Mozilla Firefox\ refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location."
I also tried the same for the file in the x86 folder but it gave the same error, and I went and looked for the files in the location given and they were there.
Firefox didn't crash, so there aren't any other error messages I can give you.
The things I had bookmarked are really important, I can not lose those, but other than that I'm fine with anything else needing to re-installed, etc.
Help please?

But I can't... find... it... It's not there.
Unless you're talking about the entire Mozilla Firefox folder (which isn't what the thing you copied says,) there is no installation folder.

Downloaded latest version and now firefox won't open "mozjs.dll not found"?

I downloaded version of firefox (5.0?), and when the computer restarted firefox won't open. I get a "mozjs.dll not found".
Help?

'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''''' {web link}

I just did two System Restores (and clicked something that asked me about "[something -exe]," and now Firefox won't open at all.

I hope someone can help. My husband did something to update Firefox (or Firefox just automatically updated today, I don't know which), but I didn't like the new toolbar much, so I did a System Restore to get back the old one. That didn't work, so I then did another System Restore for an earlier day, but when I restarted the computer, Firefox wouldn't open at all.
A pop-up asked me something about "allowing 'something-.exe' at start-up," with options like "Remember this action, don't allow, and allow," I think, and I don't remember what I clicked, and that's likely part of the problem, but in any case, I can't get Firefox to start now. I click on the logo/icon and nothing happens.
I tried to undo both System Restores, but the computer would only restore the most recent one, not both.
And I tried, as suggested on the forum elsewhere, to go into "Firefox Safe Mode," but that didn't help either.
Thank you for any help.

That's what happened to me too after I upgraded to firefox 4 and it wouldn't connect to my internet. Now I'm stuck with Internet Explorer with none of my important personal information like my favorites.

How do you completely disable the installation and use of add-ons for firefox 4? Is there a config setting/file that can be changed to completely disable add-ons?

I want to completley disable the installation and/or use of add-ons in Firefox 4. I don't want anybody that logs onto either of my computers to be able to use add-ons and I can't find a way to disable it in the configuration files. I've found ways to lock down other options like updates etc. but I cannot find a way to completely disable add-ons.

See:
* http://kb.mozillazine.org/Locking_preferences
You can use a mozilla.cfg file to lock prefs or specify default values. 
You can place a file local-settings.js in the defaults\pref folder to specify using mozilla.cfg.
You can use these functions in mozilla.cfg:
defaultPref(); // set new default value
pref(); // set pref, but allow changes
lockPref(); // lock pref, disallow changes
To prevent users from installing software use:
<pre><nowiki> //
lockPref("xpinstall.enabled" ,false);
</nowiki></pre>

My firefox won't open at all on my user id on Windows 7, it keeps saying 'Firefox is allready running but isn't responding' etc.

I install firefox normally, on my user id on Windows 7. But it won't open. It keeps saying 'Firefox is allready running but isn't answering. A new window can't be opened until all of firefox' processes have been shut down or the system rebootet.
This is a translation of the text as my user language is finnish.
I've also checked my fathers user id on this computer, there the firefox works, no problem.
I suspect the problem was born when I tried to take an old firefox backup into use. I think I did it wrong... Or, the backup was to old.

You can try to move the entire Firefox folder to a different location to make Firefox create a new file structure for the profile folder.
* Vista/Windows 7: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\
* "Application Data" in XP/Win2K and "AppData" in Vista/Windows 7 are hidden folders.
* Use %APPDATA% in the File name field
* http://kb.mozillazine.org/Show_hidden_files_and_folders
Go to: Control Panel > Folder Options > "View" tab > under "Hidden files and folders", select "Show hidden files and folders" 
To see the file extensions of all files uncheck the box "Hide extensions for known file types"

Firefox won't open at all since May 4 update, yet no error message appears. Am not savvy/brave enough to test for corrupt Profile data. HELP, PLEASE!

Tried to start Firefox 3.6.16 from Desktop May 4. Instead of opening, message showed an update in progress, then a message that it could not install because two Firefox programs were running (?). After the install message closed Firefox wouldn’t open from the Desktop, the Start Menu, or the Run command. I’ve rebooted numerous times & even did a System Restore to May 3.
C:\Program Files\Mozilla Firefox currently shows only one firefox.exe, last modified 03/23/11, and the only changes May 4 to chrome folder (6 Executable Jar Files), components folder (browser.xpt), & blocklist.xml.

Thank you very, very much for providing the simple, concise directions that solved my problem! After sorely missing Firefox 3.6.16 for a month, today I finally worked up the courage/got desperate enough to attempt (with much trepidation!) the download and re-installation.
Step 4 was a bit of a challenge, but following Uninstall directions in the 3.6.16 Release Notes advising removal through Control Panel appears to have preserved my Profile and worked fine. Was not quite sure how to go about properly removing the Firefox program folder, so I opened Local Disk (C:)/Program Files/ and deleted (to Recycle Bin) the Mozilla Firefox folder – and am keeping fingers crossed that that was the correct method.
It was quite a satisfying thrill when Firefox 3.6.17 opened, but very distressing to note that “Firefox 3.6.x will be maintained with security and stability updates for a short amount of time. All users are strongly encouraged to upgrade to Firefox 4”. Sadly, it seems all things Internet seem to be evolving towards mobile devices, social networking, and the ability to sync all the fancy new toys – and getting much to complex for us old dogs who don’t learn new tricks easily, or need them for that matter.
Thanks again!

Firefox 4 could not be made to show bookmarks on Vista 64bit. I used system restore to get back to older version. Now Firefox won't open at all even after undoing system restore

I use Vista 64 bit. Was fine with older Version of Firefox (3.6, I believe). Upgraded to Ver. 4. Couldn't access extensive bookmarks file or bookmarks toolbar. Tried all the Firefox help recs and they didn't work. Clicking the top button would give list of toolbars but when I tried to move to bookmarks toolbar the menu changed. Tried going thru tools and options and that didn't work. So decided to use System Restore to get old Firefox version back. Icons remained but program wouldn't open. Tried many ways, including start menu. Old version is still on program control file but only option is to uninstall. So went back to System Restore to get Vers. 4 back and it's not there. What to do?? I can use Google Chrome or Internet Explorer but I want all my 100's of bookmarks back. Thank you.

My profile is missing so Firefox won't open at all. How do I reset it then?

I had been using Firefox for a while off and on, but was using a different browser as my main one. Now that that browser is outdated and there's no update available, I wanted to switch to Firefox permanently. Since all of my bookmarks are only updated on my old browser, I thought it would be much easier to just uninstall and reinstall Firefox and automatically carry over my bookmarks (since it did that the first time a while ago). While looking up how to install it, I came across something that said the bookmarks are stored in a "profile" which needed to be deleted in order to be reset. I followed the instructions to delete my profile, and then uninstalled and reinstalled Firefox.
NOW, I go to open my newly installed Firefox and a window comes up that says: "Your Firefox profile can't be loaded. It may be missing or inaccessible." ...Well, I wanted to start over completely, so of course I don't have a profile anymore. But my only option now is to click out of that window, and Firefox just disappears. No way to access anything on Firefox, no options, no anything so all of the so called "solutions" I've seen (IE: resetting the profile... I can't do that either!) are impossible for me to do.
All I wanted to do was start over completely with Firefox which seemed like a very simple solution and has now turned into a hassle and an unusable browser. How can I reset or create a new profile without being IN Firefox to do it? Was deleting my profile a mistake? If so, your help page is very misleading!
Someone please help. I really don't want to use ANOTHER browser.
Thank you!!

I'm having the same problem as the OP, I can't find that file "profiles.ini"
can't re-install firefox, deleted all files related to Mozilla and Firefox, still locked out by missing Firefox profile
I posted on my own problem recently w/ no response (https://support.mozilla.org/en-US/search?a=1&asked_by=GPStyne&w=2),
so far all posts on this support page have been confusing and I've been unable to find any of the things they spoke of trying to change it.
at this point I'm begrudgingly running Safari hoping someone can help me fix this, can't believe i can't just delete all and reinstall like a normal program/app

Firefox won't open at all, for 3 days now, no errors show, simply nothing. How do I get it & bookmarks back. PLEASE.

Hi, I was happily using Firefox all the time and suddenly when I click on the icon to open it nothing happens and thisn has been going on for 3 days now. I have tried all different ways to open it, but same thing, nothing. I am worried I have lost all my bookmarks now as I hadn't saved them. I also would like to know if they can be recovered at all and also how do I go about getting firefox back and why did it stope working anyway. Any help would be greatly appreciated. I am using explorer at the moment, my system is Vista. My bookmarks were very important

Firefox won't open at all

Firefox ia not working, it will not open at all, although it is showing up on the bottom bar as if it IS open. I have tried un-installing and updating it but it is still happening.

Hi jules78,
There is a [https://support.mozilla.org/en-US/kb/Firefox-not-start Knowledge Base article] that covers this topic. It might be useful.
Have you tried starting Firefox in Safe Mode? Hold down "shift" while Firefox is starting up. If the crash doesn't happen in Safe Mode, you should read [[Troubleshooting extensions and themes]].
There is also a lot of useful stuff in the [[Firefox crashes]] Knowledge Base article.
Hopefully this helps!

Firefox won't open at all. None of the troubleshooting suggestions work

Everytime I click on firefox it does not open at all. I checked to see if a previous window never closed. I uninstalled and reinstalled it. I shut down and restarted my computer several times and I don't know what else to do.
