i have installed firefox i am using windows xp i have the icon on my desktop and it is in program files but it will not open?

* 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 downloaded new Firefox but now can't open Firefox at all. It says it is not supported on my system. How can I get the earlier version which I deleted?

Reboot and try again.

I just upgraded to FF 4.o, had 3.X running just fine, the upgrade went fine, but now it won't open Firefox at all.

I just upgraded to FF 4.o, had 3.X running just fine, Windows 7, the upgrade went fine, but now it won't open Firefox at all, it just loads and sits there and stops, but my task manager shows FF running in the background, I have tried reinstalling twice, no change, what is causing this?
Processes is the only place it shows Firefox running, programs won't show it in Task Manager.

Reinstall 10.6 again, but this time hold c boot off the 10.6 and erase the ENTIRE internal drive.
You do this by selecting the drive makers name and size on the left hand side, not the slightly indented partition underneath it.
If you erase and install 10.6 only into a parittion, say Macintosh HD, the you still have the hidden Lion Recovery Partition on the drive and it appears you already have 10.7
In the MAS, hold option and click Purchases to redownload Lion
FYI, you don't need to install 10.6 to reinstall 10.7, 10.7 can be reinstalled via the Lion Recovery, Command r boot.

Please help, I cannot open Firefox at all! crash ID: cf9fa02c-586d-4033-999b-a7a242110501 and Signature: mcffplg.dll@0x1cb20

It happened a few weeks a go, I have re-installed the Firefox but still didn't work. I can only open Internet Explorer. I cannot open Firefox and Google Chrome at all!. I am using windows 7.
Please help, I want my Firefox back...

The crash is reporting a problem with the McAfee Site Advisor (mcffplg.dll), try uninstalling the McAfee Site Advisor and see if you can then start Firefox.

I cannot open Firefox at all!!!

I really hope someone can help me with this it's driving me crazy to have to use Internet Explorer.
All of a sudden yesterday when I booted the laptop up, I have been unable to open Firefox. I click on it, and just nothing happens whatsoever. I've tried EVERYTHING, reinstalling, running in Safe Mode (still nothing happens) and literally nothing works.
What can I do? My laptop is a 1525 Inspiron running on Windows Vista.
Thanks, Lisa

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components; this won't normally affect its library, but that should be backed up anyway.

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

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).

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.
Please report back to see if this helped you!

I cannot open Firefox at all... receive "Profile Missing" -- what next?

MAC desktop being used. When I click on my Firefox app it looks and looks then brings up a window: Profile Missing.
Obviously, I cannot do much without opening Firefox.
What do I do next?

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
