Firefox 4 will not open but returns to reboot request over and over how do I get past this?

I downloaded the Firefox 4 update and now can not open Firefox. I have had to go through google browser to reach Firefox. The screen keeps coming up with instructions to reboot after the download. I have done this several times. I can not find Firefox in my program list at this time .

Take it to an Apple Store, have proof of purchase with you.

After startup firefox will not open immediately sometimes must reboot laptop ??

after start-up I double click on the desktop icon or right click to open and FF will not open. I then must reboot the laptop and it usually opens. It seems to reopen ok later after closing the browser during the day. I had a box appear on opening for awhile that showed some upgrades for some apps (that I always declined) and then it went away after while. Sometimes when I go to open the box appears very briefly and as just a border of the box and then disappears. Could that be the reason for the hangup? Any input would be helpful. Should I maybe just reload the latest upgrade. thanks ahead of time helpful people. :o))

Try a clean reinstall.
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 7.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
* Remove the Firefox program folder before installing that newly downloaded 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 in the Firefox Profile 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 installed Spyware Doctor with antivirus and Firefox will not open but goes into Not Responding mode

After installing PC Tools spyware doctor with antivirus Firefox will not launch. I get a black screen with a not reponding message at the the top. I have tried an earlier version of Firefox (5) and this launch OK until I closed it and then it too refused to launch.

Hit the '''Alt''' key to show the Menu bar, then open View > Toolbars and select Menu bar and Navigation bar, so they have a check-mark.

Firefox will not open but process runs

Suddenly I can't get Firefox to open - process runs in task manager but no window comes up at all. Have been using it on this system for a long time with no issues. It isn't the process already running issue which most of us know.
Have tried uninstalling and reinstalling Firefox to no avail. I have no other monitor connected and desktop is not extended to an imaginary monitor where it may be opening. Running on Windows Vista.
The problem started when Firefox hung / crash / froze trying to run a video applet on a website (bbc.co.uk).
Is this an issue with any kind of known resolution or must I find a new browser after years being comfortable with Firefox?

I have exactly the same problem with both Firefox and Thunderbird, under my Windows Vista OS. However, I can get both running using the following cumbersome method. In the Task Manager right click the entry firefox.exe in the process window. Choose "Properties" from the drop-down list and then choose the "Previous Versions" tab. In my case it showed a so-called "shadow copy" dated about four weeks previously and when I selected this and clicked "Open" then Firefox opened normally, though rather slowly. Unfortunately this does not solve the problem because after Firefox is closed the same problem recurs next time I try to open it. However, if the "Restore" button is available (it was not for me) in the "Previous Versions" window then you might be able to restore an older but working copy. You can also get to the "previous versions" window by right clicking the firefox.exe file in the installation folder (usually C:\Program Files\Mozilla Firefox\ ).
This is a really unfortunate development in Firefox and Thunderbird that will force people to abandon them and move to equivalent Microsoft products that do not have these problems. Mozilla developers please act on this problem urgently.

Firefox will not open (have tried "run in safe mode" and other alternatives)

firefox unexpectedly closed; i tried to reopen- no luck; rebooted computer and "add-ons" opened but firefox did no! now firefox trys to open for about 10 sec and then quits trying. i have no messages/promts or any kind of other indication that there is aproblem (other than the browser won't open). i am using google chrome to post this request. thanks in advance for any suggestions! bill crimmins

See http://kb.mozillazine.org/Browser_will_not_start_up
Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, 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.

I had a pop-up from Mcafee yesterday with option to block a particular access request, today Firefox will not open but shows the message with "try again" -please help.

I assume that I inadvertantly authorized McAfee to block Firefox .
How to unblock ?
thanks for helping.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:

Firefox will not open. I have tried re-installing and deleting my profile and nothing has worked.

I tried to download an extension for Firefox and after that it just stopped working, no response. I have tried re-installing the browser, deleting files & profiles. Nothing has worked. I cannot access the profile manager either *sad face*

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems?esab=a&s=troubleshooting&r=3&as=s#w_5-reinstall-firefox here].
WARNING: Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be recovered unless they have been backed up to an external device!

Thank you.

Firefox will not open, it goes right to crash reporter, and it will not open in safe mode(crash reporter again).

I added adblock, that seemed to work OK. The same day I was tracking down slow download speeds with my ISP and they had me go to, I think...I can't remember to well, the tools menu and erase cookies, passwords, etc. I don't remember what else was erased,
in order to "speed up my browser". Maybe I shouldn't have blindly done that. Anyway, when I tried to start Firefox it just goes straight to the crash reporter. It opens fine under Admin and other users.

Uninstalling and reinstalling Firefox doesn't usually solve anything, because most problems are contained in the profile.

Based on the value of the ''keyword.URL'' preference, it looks like your system is either infected with malware, or was at some point in the past. You also seem to have a user JS file, which could prevent you from modifying certain preferences.

Nothing like this has ever happened before; 2-1/2 months ago, latest version of Firefox recommended to me by 2nd Level Technician from AT&T U-VERSE; as yoou are well aware, IE-8 may react differently from day to day! AT&T U-Verse said off the record to me that sometimes IE-8 gives them Fits" I do nopt kno0w where to turn; U-Verse Techs only solve specific U-Verse problems! All of this suddenly occurred today;it's bizarre????

Firefox will not open...please help.

My Mozilla Firefox will not open any windows, although it does start and show as running in my task manager. I have uninstalled and reinstalled it twice now and restarted my computer twice.
I CANNOT start Firefox in safe mode by holding down shift or using the "firefox/safe" in the run box.
I've tried it with applications closed, and open....I've tried it online and offline, I tried to run it in compatibility mode, I checked my computer for viruses...nothing helps.
I have read every troubleshooting item here but they only say try safe mode, or do something from Firefox when it is open such as reset it. I have no add-ons or extensions on Firefox and it just worked yesterday...also my computer is brand new Windows 8.1 12GB ram 2TB harddrive and everything else works fine.
please help
