Firefox will not launch - when i double-click the icon it does nothing. But when I go to the task manager in Windows it shows that Firefox is an active process.

**Running Windows Vista 6.0 SP1 with Firefox 6.0.2

Firefox will not launch, but shows in task manager, after updating graphics drivers to AMD's 13.1.

Hi,
After updating to the AMD 13.1 drivers, on my 5770, Firefox will not launch; it does, however, show in the task manager. I should note that it will start in Windows safe mode; when I had it open in safe mode, I used that time to disable all plugins, add-ons, extensions, and created a new profile. This did not help. I also tried launching Firefox in to its safe mode, and had no luck with this either.
I experienced this problem once before, when trying to update to a previous version. I believe I was moving from 12.1 to 12.4, but I'm not 100% sure of that. Ultimately, my solution then was to retrograde back to my previous driver. The steps mentioned in the previous paragraph did not help at that time, not did a complete reinstall.
15 years of computer repair experience, and this has me baffled.
Thank you to anyone who might be able to help.
Possibly relevant specs.
Windows 7 Ultimate x64
AMD Phenom II x4
6BG Ram
AMD 5770 graphics, running Catalyst 13.1

By any chance, did you disable Firefox's use of hardware graphics acceleration? To avoid a round-trip through Windows Safe Mode, you could try adding these to your prefs.js file while Firefox is closed.
To quickly open the folder with the correct prefs.js file, you can use
Help > Troubleshooting Information > "Show Folder" button
Because Firefox may overwrite change to this file at shutdown, you should edit it after closing Firefox and allowing a few moments for Firefox to finish updates to the files.
These are the preferences I think are most relevant:
user_pref("gfx.content.azure.enabled", false);
user_pref("gfx.direct2d.disabled", true);
Does that make any difference?

Firefox will not launch

firefox will not launch after upgrading. Every time I try to launch I am advised to reboot to complete the upgrade.

I think you already known that latest firefox version 13.0.x don't work with xp sp1, needs sp2 and above.
Try [https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer Uninstall Firefox from your computer]
then Download the latest version(with your safari) from :
http://www.mozilla.org/en-US/firefox/all.html
and Install the version that you have downloaded (13.0.1).
Do not select to remove your personal data, your profile data is stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder], so you won't lose your bookmarks or other personal data.

Firefox will not launch after latest OS X security update

Just installed latest Apple software update on Snow Leopard. Now, Firefox will not launch. Checked system logs and get this:
11/21/10 10:24:20 PM com.apple.launchd.peruser.501[155] ([0x0-0x6d06d].org.mozilla.firefox[802]) Exited with exit code: 1
The following may or may not be related. Before installing the update, I had lots of these messages in my logs:
11/21/10 7:27:17 PM firefox-bin[39594] *** __NSAutoreleaseNoPool(): Object 0x1422680 of class __NSCFDate autoreleased with no pool in place - just leaking
11/21/10 7:27:17 PM [0x0-0x493493].org.mozilla.firefox 2010-11-21 19:27:17.323 firefox-bin[39594:903] *** __NSAutoreleaseNoPool(): Object 0x1422680 of class __NSCFDate autoreleased with no pool in place - just leaking

Sounds like you may have a check in the box for HTTP and/or HTTPS proxy servers, but you are not behind a proxy server. Safari and Software Update use the HTTP port, Mail doesn't, and Firefox ignores the Mac OS preferences and uses it's own proxy settings.
Go to System Preferences > Network > active connection > Proxies tab and if there are proxies checked, UNcheck them.
Hope this helps...

iBooks can not be read on macs, only on iDevices.

I upgraded from 3.6.13 to Beta 4.0 and now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing.

I uninstalled Beta 4 and re-installed 3.6.13 now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing, I have been using Firefox for a long time but cannot resolve this problem can anyone help and give me a solution please. As I use Firefox as my web browser it is very frustrating.
The fact it will not uninstall appears to be something completely new as nobody I know who uses Firefox has ever encountered this in the past.

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 am trying to download icarly episodes and it does not go any further than clicking on buy season button. nothing happens when i click the button?

I would first try resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.

My ipad will not swith on. It was working fine an hour earlier but when I press the power on button nothing happens. I have had it on charge just to be safe but no joy. What options do I have?

My ipad will not swith on. It was working fine an hour earlier but when I press the power on button nothing happens. I have had it on charge just to be safe but no joy. This is a basic first version ipad. What options do I have?

Try a reset. Press and hold both the home and power buttons 10-15 seconds till the Apple logo appears. Release both buttons. Wait 15-20 seconds till your iPad starts on it's own.

HT201263 when i follow the steps it does it but when it gets to itunes it says 'iTunes could not contact the iPhone software update server because you are not connected to the internet' but i am connected to the internet ..?

Were you definitely connected to the internet at the time? If you don't have iOS 5 on your iPhone then the only way to update it would be via iTunes, once updated to the latest version of iOS you'll be able to update your iPhone without connecting to iTunes "over-the-air".
Before updating however it goes without saying to Backup your iPhone, this should happen by default upon connecting your iPhone to iTunes.

Suddenly, Firefox will not launch. When I try with the Task Manager up, it never appears on the list of applications.

On a desktop PC running Windows XE, FF will not launch. Has been working very well since we installed FF two weeks ago and made it our default browser. IE launches normally allowing me to post this question. On my laptop, on the same wireless connection, FF works fine. I have rebooted several times. Everything seems normal except for FF. I have run PC Doctor and have fixed all problems that came up. McAfee finds no problems.

Update: After a very long time, perhaps 15 minutes or more, the FF screen comes up blank with the "loading..." message on the first tab. Also, because I tried several times to launch FF, more such screens came up with the same result. My home page never loads. If I stop page loading and try another web site I get the same result.

I get a crash notice. Firefox will not launch at all -- it keeps giving crash notice. I also cannot generate a crash report. I have uninstalled and reinstalled -- same issue. It does not launch.

Firefox crashed this morning. It will not launch even after being uninstalled and reinstalled. All I can get is a crash box. It will not relaunch in any way
== This happened ==

This sounds the same as my issue. I was browsing in Firefox v6.0 last night and all of a sudden it closed with no notice or error message. When I tried to open FF I received the messaga; We're Sorry - Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts." I does not restart. I have been using IE to browse for a solution and nothing works other than opening as administrator. Now this problem is only on one of my laptops and is fine on my desktop and other laptops so it appears to be something specific to my laptop which is running Window XP Home and Service Pack 3.
Some suggestions were to change the profile (did not work), end the firefox.exe process in task manager (not running in processes) and delete an xpicleanup.exe (not listed).
The only thing that works is to run as administrator but I have to do this everytime. Is ther a solution?

After updating firefox will not launch

Ever since version 8 became available whenever I update FF it will not launch. No error messages or anything, just no response at all from the button. I have cleared the cache and cookies, completely removed FF using the control panel - add remove programs, deleted the FF folder from C: program files and then emptied the trash. then downloaded a fresh copy of FF from www.mozilla.org. Again no response at all when attempting to launch. not even an error report. I am running Microsoft XP Pro 5.1.200 SP 3 Build 2600 on a Dell OptiPlex 745 processor x86 family 6 model 15 stepping 2 intel ~1794 mhz

What about the latest version of Firefox, Firefox 9? Does that work?
If it doesn't, the instructions here might be of help: [[Firefox will not start]]

Unable to remove iLivid from Firefox because Firefox will not launch.

I am attempting to remove iLivid from my computer. It has hijacked my browser. I removed it from IE and Chrome; however, I am unable to remove it from Firefox because it will not launch. How can I remove this "thing" from Firefox if it will not launch???? I used the shortcut on the taskbar, the icon on my desk top and also the navigation menu. None will launch Firefox.
