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.
See:

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
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

* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0.x: http://www.mozilla.com/en-US/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.
* Do not 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.

I don't know what version of Word that is, it may be very old indeed.

Opened FireFox and have a continuous annoying police siren!! HOW do I turn OFF??? when firefox closed, siren goes away
== This happened ==
Every time Firefox opened
== this morning when I opened FieFox (May 21)

It's Pac-Man's 30th Birthday today, and Google's homepage is a playable Pac-Man game around the Google logo. My boyfriend had the same problem, then I went to Google and was like Hey, it's Pac-Man! And then the siren started. He plays fine on my laptop, but for some reason the music is stuck on his computer.
All you have to do is disable the "Cool Previews" add on for firefox. Go to the "Tools" link at the top of the browser, go down to "Add Ons", go to the "Cool Previews", click "Disable". Then restart firefox and it should be fine!

When I open Firefox I have to try several times because a Runtime Error with the program C:\Windows\System32\regsvr32.exe

'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "Continue in Safe Mode."''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''

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:

#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.

I am not clear what your problem is and importantly whether you are trying to ask for help with Firefox.
If you have a Firefox problem can you explain what you need help with please. If the problem is with a new Windows 8 operating system you will need to find a suitable forum to discuss that.
A websearch will turn up many suitable fora one possibility is

The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.
If you want to leave feedback for Firefox developers, you can go to the Firefox ''Help'' menu and select ''Submit Feedback...'' or use [https://input.mozilla.org/feedback this link]. (You'll need to be on the latest version of Firefox to submit feedback).

Can only open firefox once, have to restart to open more than one browser. can't upload any pictures the box doesn't pop up, my browser settings are diff now

Firefox just changed out of nowhere. I can only open firefox once... I used to have atleast 2 browsers up using them both on different sites, but now I can't have but one firefox browser up (not tabs, but firefox pages) Also when I am trying to upload images on ebay or any other site nothing happens... nothing pops up. I click it over and over and nothing even pops up. This is exactly what happens with the firefox browser in my first question... I can click the firefox icon a million times and nothing comes up. My tabs are all gone and it doesn't show anything like I had before this all changed? Did I reset everything some how? I do not recall clicking anything to go back... I do remember clicking an update because it kept poping up so I did it and that is the last thing I remember before this happened! UGHHH!

As I asked previously are you able to have tabs open as a window by using the right clicking option ?
When you close Firefox you should use
*'''Firefox button -> File -> Exit '''
Are you doing that ?
I suspect what may be happening is Firefox is hanging as it closes down.
* see [[Firefox hangs or is not responding - How to fix#w_firefox-hangs-when-you-quit-it]]_firefox-hangs-when-you-quit-it
* this explains how to check & if necessary kill the process [["Firefox is already running but is not responding" error message - How to fix it#w_end-firefox-processes]]_end-firefox-processes
A related possible problem is that you may have built up many copies of the restore files. These are stored in the Firefox profile. The easiest method of finding the profile location istouse
*use '''Firefox button -> Help -> Troubleshooting Information -> [Show Folder]'''
*see [[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]
You need to look for the files ''sessionstore.js'' and numbered duplicates of that. Delete them.
* see http://kb.mozillazine.org/Firefox_hangs#Multiple_sessionstore.js_files

I cant open firefox, everytime i click on it it just fades away!

I have reinstalled it but it still doesn't work. And the little app thing on the pc, when i click it it just fades away. Can you please help!!

Hi JakeBubber ,

More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
WARNING:Do not use a third party uninstaller as part of this process.

Cant open firefox on second screen on computer with two screens with two graphics cards.

I have a computer with two screens and two diffrent graphics card. One of them is onboard GC and another one is USB GC. I am running two instances of FF and it works fine with 3.6.20 version. But when I update to the latest version of FF either 5 or 6 this does not work. Even if i try to open one instance of FF on second screen on USB GC , I cant see anything> i have to move it to the main screen to see the FF window and will not work on the extended screen. I am using windows 7 pro 32 bit and the screen resolution is set to 1280x1024 on both the screens.
Can you please help.
Thanks.

Try to disable hardware acceleration.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
