If that doesn't help then do a clean reinstall.
Clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0: http://www.mozilla.com/firefox/all.html
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* 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.

Firefox will not load no matter what I try (safe mode whatever). It only loads if I run it inside Comodo sandbox! How do I get it to run the normal way?

Firefox will not load the normal way (clicking on a link or running it from Run window or even running it in safe mode). It only runs if I dig down to the installed directory, right-click firefox.exe and select "Run inside Comodo Sandbox". I have Comodo Internet Security Suite installed but this does not happen with other programs. Do send in your suggestions. Re-install did not help.

Firefox will not load to the web, even after 2nd download.

I have used firefox as a web browser because our school page works best with it. I have used firefox for over three months. This weekend firefox will not load. The screen message says unable to load web page, try again button is displayed, all to no avail.

I have XP Pro. I tried installing 3.6.15 and could not open it. I did a system restore and 3.6.14 would no longer open. I tried again installing 3.6.15 and got a message that the previous version had not uninstalled properly. Tried uninstalling.
As a precaution I used MozBackup to save my bookmarks etc. and also saved a system restore point.
I then clicked Start, My Computer, drive C, Program Files and deleted the Firefox folder.
I installed 3.6.15 and it is now working fine with all my bookmarks and addons loaded automatically.

Firefox will not start after an update, I cannot log in to Firefox in any manner.

Firefox does not work any more and every time I attempt to access it (even in Safe Mode) it displays the following message:

I have absolutely no way of getting into Firefox to undo whatever has gone wrong, is it still possible to solve this without having to completely purge and reinstall Firefox?

The ''real issue'' is what is going on. On one machine the update process works, but on my other machine it does not.

Firefox will not start after interrupted update to 5.0

Lenovo x200 | Windows 7 32bit | Firefox 5.0
I was updating Firefox from version 3.6 (I think) to 5.0. Simultaneously I had done a update on Windows that seemed to have stopped. The update of Firefox had also come to a stop. As I remember it the installation was complete, and I was attempting to start the program, when Firefox was checking compatibility with installed plug-ins and so forth.
The Windows updates installed fine afterwards but after several reinstalls of Firefox, I still can't seem to get it to start.
There is no error message or notification at all when trying to start Firefox.
One processes is created, staying steady at 50% CPU and 26 404 K memory.
If i try to open another instance of Firefox I get a process that takes 0% CPU and about 1 844 K memory.
Summary:
Firefox fails to start after interrupted update to 5.0 from 3.6.
There is no error message.
Firefox never starts (and the process never shuts down), just shows in the Task Manager under Processes steady at 50% CPU and about 26 000 K memory (I've seen it do this for at least 20 minutes, before terminating it).

Mac Mini will not load after recent update.

My late 2012 model Mac Mini just had a software update and upon rebooting, my login name did not populate. I rebooted again and now I get the gray screen with spinner and progress bar. Once the progress bar loads I have just the spinner for a minute or so before it cuts off completely. I use a wireless MAC keyboard and it will not load into safe mode when I try holding down SHIFT upon reboot. Any suggestions?

Firefox will not load after an auto update

I am running Windows 8.1, 64-bit operating system. I think that FireFox automatically updated today and now I cannot start FireFox. I get a box that states add-ons are being checked for compatibility. The 32-bit designation is shown and it just spins and spins and will not go beyond that screen. I've tried everything I can think of to start FireFox but nothing seems to work. Help I'm having to use IE and I hate it.

Create a new profile as a test to check if your current profile is causing the problems.

Firefox will not open after new update; Error: Platform version '1.9.2.13' is not compatible

After accepting the new update I got this error message when trying to restart Firefox:
XULRunner
Error: Platform version ‘1.9.2.13’ is not compatible with
minVersion >= 1.9.2.14
maxVersion <= 1.9.2.14
I have tried:
- Opening in Safe Mode; same error
- Uninstalling, deleting remaining info in C>ProgramFiles>MozillaFirefox folder, and reinstalling.
- Updating Avast antivirus in case that was interfering.
Now when I try to start Firefox I get this message;
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.
But there is nothing happening in the Windows Task Manager. Please, somebody save me from Windows Internet Explorer!!

I experienced this error updating from Firefox 3.6.13 to 3.6.14 and resolved it by doing a 'clean' install' as described. It occurred again in updating from 3.6.14 to 3.6.15 and this time a clean install failed to rectify it. (Anyway, I don't want to have to go through this every time.)
Work-around: Shut down Firefox. Edit application.ini (typically "C:\Program Files\Mozilla Firefox\application.ini")
[Gecko]
MinVersion=1.9.2.15
Change to 1.9.2.13
Save. Start Firefox. Dirty? Yes. Works? Yes.
(Gecko is the forerunner or XULrunner)

Firefox will not start after an update.

I have to manually uninstall Firefox and manually install the update every time.
I asked a similar question before. The response was to start in safe mode. BUT the program will not start. It acts as if there is a software switch set to "don't run this program under any circumstance." The switch is either in the registry or among the program files, because these both get cleared on a manual uninstall. The update procedure is not clearing the registry or the program files.
Does the update process uninstall the previous version and then install the update version?
Part 2 --
I often cannot find the update manually on the Firefox site.
I am on the Beta release channel. The current release is 33.0 beta 4. However, the most recent on the site is beta 3. Where is 33.0 beta 4?
OS is Windows XP latest release.

Firefox will not load Java in Linux - even after following all instructions on net I can find - what am I doing wrong??

The problem I've got is I'm currently running Puppy Linux on my laptop.
Now I've tried everything I can to get Java working under either Firefox, Chromium or Seamonkey (I have all three browsers on my computer).
For firefox and seamonkey I have tried the following -
downloaded the tar.gz file for java
unpacked it to /opt/java
gone to /user/lib/mozilla/plugins and run the command
ln -s /opt/java/plugin/i386/ns7/libjavaplugin_oji.so
to create the symbolic link to the plugin
checked that the plugin is executable (actually even tried giving everything full permission to read/write and execute it)
For Chromium done a similar thing but put the symbolic link in /usr/lib/chrome-linux/plugins folder instead.
Restarted the web browser, even tried restarting X Server in case the browser is running somewhere in the background.
All three browsers can pick up all the other .so plugins in that folder except Java.
When I click check plugins on firefox I get to the page about "Missing Java? - For your safety Firefox has disabled your outdated version of Java. Please upgrade to the latest version".
However the version I've downloaded is Version 7 Update 9 which is exactly the same one that is available as the latest version from Java themselves (it was only downloaded from that link a couple of minutes before, I've even tried re-downloading it just in case there has been an update within those 5 minutes).
If I go into the Java folder and run ControlPanel the Java control panel pops up and it knows where Java is installed and everything.
So what on earth is going on? Am I installing the plugin in the right directory? I'm guessing so as that is where all the other plugins are stored and Firefox, Chrome and Seamonkey are picking all the others up fine, or could there be an older version of Java lurking around somewhere on my system that Firefox, Seamonkey and Chrome are all trying to use?
I've also tried downloading the RPM and installing that into the /usr/java folder and replacing the symlink from /opt/java to the one in the /usr/java folder and still nothing.
I just really can't understand it 'cos it's picking up all the other plugins like Gecko and even installed Flash in the same way and that works fine.

Thanks cor-el looks like Oracle need to update their linux installation instructions then. If only I'd have known that before doing all sorts to get it working.
I now have Java in Firefox, Chrome and Seamonkey :) :) :) :) :).

Firefox will not open after recent update of all computer lab servers, Windows server 2008 R2, Multipoint 2011

All 3 computer lab servers were recently updated and rebooted. Java was updated as well to 7u21. Now all 3 do not respond when Firefox icon is clicked, from any thin-client or remote desktop session/user. There is no popup error, just an hour-glass for about 5 seconds and then nada. IE is fine. I can't tell if it was the java update or a windows security update, and I'm not seeing anything in the error logs

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 internet for Firefox and the plugin-container process and the updater process.

Firefox will not load any web pages since update

Using Galaxy Nexus, installed update today. I have ICS version 4.0.1. Pages will not load at all. Even the firefox pages on the home page will not load. I verified with using both wifi and my network, and checked the stock browser from the phone which works, but no success with Firefox. I uninstalled Firefox, restarted my phone, re-installed, and the same issues are happening. Any idea how to get this back to normal?

Update..when I open firefox from scratch, the main firefox pages on the home page seem to work. But as soon as I try to go anywhere else, IE going to a website in the address bar or even trying to access the defauly bookmark links, it just sits there loading but never brings anything up.
