Firefox won't start whenI click on the icon; info on help page doesn't help

I have Windows XP and Verizon Internet Security Suite. I've installed Firefox twice (with an uninstall in between) and it still won't load when I double-click on the icon. It runs fine on my other laptop with same OS and same anti-virus/firewall. Info on help page doesn't actually address this problem, even though the headline indicates it does.
== This happened ==
Every time Firefox opened
== Firefox has never actually opened. I double-click the icon and nothing happens. Check task mgr, it's not listed. ==

See my update at 6:46PST - having the very same problem on a MacBook Pro. Someone named "Sherry" posted around 5:42PST w/ same problem. No techies are picking up on these posts, though. Please add a comment to mine as well to keep it at the top and see if we can get some visibility to what is obviously a bug.
Did you upload a new version/update? That is what caused my problem

Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

I have been a happy user of Firefox for many years. Around last April first I opened Firefox and was offered an update to v 4.42.0.0 which I accepted. Installation seemingly went well. I forget now exactly what happened but the result has been that ever since April 1 I haven’t been able to open the Firefox browser when clicking on the Firefox icon. My computer now was running very slowly. I tried to uninstall Firefox, but a popup told me I couldn’t because Firefox was in use. This confused me because I couldn’t see it being used. Only now I have found that on Task Manager processes that “firefox.exe” was consuming 99 % of the CPU. After removing firefox.exe by clicking End Process my computer ran better. I uninstalled Firefox I had on my computer and installed Firefox 5.0. Unfortunately I have the same problems: Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

Born2die! Brilliant. I am a desktop clicker and never knew Firefox had a safe mode.
Thank You!
I was unable to start in safe mode initially. The second time I disabled all of the Add-Ons and she started up just fine. I enabled them one by one hoping to track down the culprit but the problem seems to have gone away.
BTW I am running ver. 3.6.8 (in response to cor-el's earlier post) and
Firefox is in the process of downloading 3.6.10 (which I am starting to think may have been what caused this whole problem to begin with)
Incidentally, whats up with all of the Java Console Add Ons?
I have:
Java Console 6.0.11, Java Console 6.0.13, Java Console 6.0.15
Java Console 6.0.17, Java Console 6.0.20, and Java Console 6.0.21
What are they? Do I need them? Can I uninstall them? Is this due to using Open Office?
Also, .NET Framework 0.0.0 Should I uninstall it?

Firefox does not start by clicking on the icon in RHEL 5.

Firefox does not start by clicking on the icon in RHEL 5 on thin clients, also the internet proxy server usename is not accepted for java applets on webpages. However while using Firefox on the servers directly everthing works fine. This issue occurs on a server thin client environment, where the home directories are located on a 5 TB storage connected using SAS cables to the servers.

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.
See [[Server not found]] and [[Firewalls]] and http://kb.mozillazine.org/Firewalls

Firefox won't open when clicked in the dock on my Mac

Mac Snow Leopard v. 10.6.8, Firefox icon in dock, won't open when clicked

As a point of clarification, does Firefox launch if you double click it from your Applications folder through the desktop (Finder)? If yes, right click (or Ctrl-click) on the Firefox icon in your Dock and choose Remove From Dock, then drag it on again from your Applications folder. The only other thing I can think is if it's already running but with its window hidden, clicking it again in the Dock might not be bringing it up. In that case try a Force Quit (from the Apple menu at top-left of your screen, click Force Quit..., choose Firefox in the list and click the Force Quit button).

Firefox won't open when clicked on

It does the windows loading symbol and then doesn't open. Only just installed it as I'm currently using google chrome and it won't let me open it.

Is there a way to go back to the way a game is started by clicking on the icon after upgrading to OS 7?

I just upgrade my wife's IPad to OS7, and now she has to go through three steps to start a game. Is there a way to go back to the older way, which was just to click on the icon for the particular game she wants to play?

Go to the table of contents is one is shown at the top of the page and then use the left arrow key or click on the left side of the page to move back to the cover page. If there is no ToC then just use the left arrow key or click on the left side of the page to move back to the cover page.

Firefox froze up. So I removed from computer and reloaded. If I close Firefox, can't restart by clicking on the icon. Have to end process in Task Manager. It then starts. Some links on some web pages won't work.

Hi,
As I say in the question I don't know what happened but Firefox just stopped operating and then became erratic. So I removed the firefox programme from my computer and reloaded Firefox.
It now runs normally but I can't run Firefox on two tabs, only one, and if I close it down during a session I can't reopen it using the desk top icon. I go to task manager, processes, and end process for Firefox - then I can start it using the icon on the desktop.
I have also noticed that some links on a web page won't work - javascript is involved.
Thanks for your herlp,
Mike FD

It sounds like you are getting in a hurry.
If you force Firefox to close in a hurry, then it won't normally start until you re-start the computer. There are ways around this, but I'm not going to go into them right now.
None-force way to close Firefox down: Close the program and wait. Do something else. Firefox appears as if it is closed, but it's not. Firefox cleans out cookies and it's cache after you close it. That takes a few minutes. You can't restart it while it's doing house cleaning.
After it is done, then you can restart Firefox normally. You can watch it in the Task Manager.
The same applies if you are installing javascript. You have to wait a few minutes.
As for running it with multiple tabs, I usually have 5 or 6, or more, tabs open at a time. Have no idea what the problem is there. Firefox needs special permission by use of a pop-up option to close with multiple tabs open.

Firefox won't start as soon as the User Home is on XSan

Hi,
We are migrating our User Home Directories to XSan.
As soon as we copy the User Home Directory from the old Servervolume to XSan, Firefox 2.0 won't start, showing an alert, that it's already running.
Deleting the Firefox preferences in ~/Library/Preferences and ~/Library/Application Support doesn't help either. Firefox then asks me to create a new profile. When this is done and a want to start with the new profile, FF tells me, that the Profile is already used.
Same thing with Camino and Firefox 1.5
Is anyone else having this issue?
Greetings from Bavaria,
ubwm

@Robert:
Be assured we thought about all that. (And Apple Germany and some consultants did as well.)
We are now rolling out using a XSan environment and user homes without mobile accounts. Mobile accounts is no solution if you need to have 300 users using 200 machines and switching machines like crazy We would have all the machines cluttered by synced Home folders in no time. We know of the drawbacks but it's the only solution that fits our needs.
Our users are discouraged from keeping large amounts of own data on their Home, which is mostly for the Library and some personal files. We keep all our production data on specialized (and non-Apple) file servers, so searching is not as tremendous an issue. (We disabled spotlight and use EasyFind).

My MacBook Pro 13in Mid-2010 won't start unless I hold the power button for about 10 seconds! Help Please!

Hello.
I have a MacBook Pro 13-inch (mid-2010):
Processor: 2.66GHz Intel Core 2 Duo
Memory: 4GB 1067 Mhz DDR3
Running Mac OS X 10.7.2
Yesterday I opened my computer (was sleeping as usual) and the screen just flasehed white and the computer powered off. The magnetic electricity thingy was connected and was green, so it was fully charged, and connected to the electricity.
Since it powered off, I tried turning it on again, and again, one second after starting to boot up, screen flashed white and the computer powered off.
I read somewhere I should hold down the power button longer, so I did, and it booted up. That's why I am able to write this. But every time I turn it off or put it to sleep, it does the same thing when I boot up.
If I don't hold the power button for 10 seconds or so, the computer won't work.
Then today, I did a backup of my entie hard drive, just in case. Later, I started using Excel, and about 1 hour after I was on it, suddenly it got really slow. Like I would click on a program like Safari, and it would take over 30-45 secs to start and be ready. And my computer is usually really fast!
I went on the Internet again, started in safe mode, boot up with option+command+P+R to reset PRAM, and nothing worked. Then suddenly on one turn-off/turn-on (since I can't restart because the computer only starts if I hold the power button for 10 seconds), again it is working at normal speed.
What can this be? Any ideas?
I really appreciate your time and help in advance
Gaby

Are you running the Apple-supplied RAM? Have you run Apple Hardware Test? I don't know what else you've tried, but this may be time to do a fresh install of Lion if you have not done so since installing Lion.

Firefox won't start when double-clicked or when clicked on from the Start menu - but other programs say it IS running.

When I go to the START Menu to start up Firefox - *or* double-click the Firefox icon on the desktop - the program will *not* start. Yet if I try to do something that may interfere with Firefox, it says to close Firefox down because it's running.... which it isn't. Even going into the Task Manager through *control-alt-delete* shows plainly that Firefox is not running... I downloaded a game through Mediabox.com to watch a movie, that may have started the problem.

No - I get the message basically saying "Can't run program while Firefox is running. Please close down Firefox & try again".
I rebooted my computer and it all works now - but that's weird it was happening before. Kinda weirded out that it happened at all.
To avoid that happening again, I still wanna know what to do to avoid it or fix it for next time. Thanks

I've just downloaded Firefox 3.6 (Mac). When I attempt to open, this message pops up: "Close Firefox: A copy of Firefox is already open. Only one copy of Firefox can be open at a time." I've removed older versions and restarted, but still get this message. What's going on?

Firefox 18.0.1 started downloading the minute I clicked on the icon. Get cloudy pages and freezing trouble browsing. Trouble signing off computer.

I turned on my computer and clicked on firefox. It immediately downloaded the new version 18.0.1 without me even clicking on it. It did the add on stuff too. I had trouble browsing after that and the pages freeze up and cloud over. I had trouble signing off my computer. I had to do a hard turn off. What's going on?

I can't open Firefox no more, I try clicking on the icon but it doesn't even load anymore.

After some time I realized I can not open Firefox anymore.
I have always used Firefox as my default browser and I really like their features, it's the best browser for me, but for 2 weeks I haven't had the possibility to open it.
I have tried many ways, such as try to open new tab, or try to open new windows, or try to open new private session but none worked. It's impossible to load Firefox. I have been searching on different sites to finally resolve my problem but it didn't help me at all.
I also reinstalled it many times but the same problem.
Thanks in advance and any help will be welcomed.

sorry for the inconvenience caused to you. This may not be a problem with the fire fox instead this may be a problem with your computer.
Plz check your computer for virus mainly "Trojan". download an antivirus and run a full scan and also be updated to latest fire fox version.

Skype not starting after clicking on the icon.

Skype not working. I have done everything possible from reinstalling/uninstalling, to doing physical hardware inspections and memory checks as well as restoring to FACTORY mode.
I have a decent understanding of computers so I am absolutely baffled.
Things to note:
-Every time I click the skype icon and it does not open, instances of it open in tskmanager.
-NO RAM damage or physical damage
-Restored to Factory Mode
-Done malware and virus checks
-Did a wipe of free Hard Drive space and after, some issues occured.
I have a DxDiag if needed.

What version of Windows are you on (XP, Vista, Windows 7, Windows 8 )? Is it 32-bit or 64-bit?

What is the version of Internet Explorer installed on your computer?
In Internet Explorer go to Help -> About Internet Explorer.
P.S. Please, don’t say that you are not using Internet Explorer. This is irrelevant. Skype depends on Internet Explorer.
