Can't upgrade Firefox because it wants me to close Firefox but Firefox is not open.

I tried several times to upgrade Firefox. The files can be downloaded and saved to the hard drive, but when I launch the upgrade I'm told that I have to close Firefox even though I have already closed it.
== This happened ==
Just once or twice
== after that I didn't try again

Did you look at the Task Manager to make sure FF is not running there? Sometimes even though you have closed FF, it might still be running its process -- alt + ctrl + delete

Can't uninstall firefox.prompt tells me to close ff,but it is not open.

I have a Dell laptop w/ Vista 32., 4 gigs of ram. Everything, video, start up programs, runs super slow.Just got Charter 30 meg service. Still runs slow. I tried to uninstall firefox ,however prompt tells me to close ff after I click the "next" button. Firefox is not running since I have previously closed it. Please help.

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!

Can't get Firefox to NOT open PDF files in the browser

I would like Firefox to always ask whether I want to open or save a PDF document. Instead, it always displays the file in the browser and pops up a toolbar. In Tools/Options/Applications pdf files are not listed. However "PDF Xchange Viewer Document" (my default PDF viewer) is listed and the action is set to "Always ask"; yet it never asks. Why?

Such actions are usually linked to a specific MIME type and if Firefox doesn't obey and ask what to do then you may have created this action for the wrong MIME type.

Installation won't complete because Windows messenger but it is not open

When I try and install Flash Player 10.x it starts and then tells me it will continue after I close Windows Messenger and Explorer. I can close explorer but Messenger is not open therefore I am unable to complete the installation. I have uninstalled other Flash player, turned off security and decreased Internet security to medium when trying this installation. Still no dice. Can someone help so I don't get stung with a $40 charge? Please

You are great!! It did what you suggested and it worked. Now I am going to go back and see how it works.
Thank you so much.
I hope you have an extra-good day. I know my day is better.

Firefox will not open because of a "nssutil3.dll" error. How can I back up my bookmarks when Firefox will not open?

Firefox would not open because of a "nssutil3.dll " problem. I've researched the problem, and I am using Norton 360 which is not a known antivirus program that deletes the file as a trojan. I want to uninstall and reinstall firefox, but first I want to make sure my book marks are safe.

I can download apps but I can't upgrade them because of an old apple ID on the iPhone?

I purchased the iPhone second hand. I deleted the old apple ID and set up my own. Downloading apps is ok but I can't upgrade them because it looks for the old apple ID password??

As already provided:
All apps are forever tied to the Apple ID used to obtain them. They cannot be updated using any other ID, nor can they be transferred to another ID.
You'll have to delete these apps & purchase them using your Apple ID. They were illegally left on your phone.

I'm using an earlier version of Firefox (v. 3.6.18), downloaded the add-on but it will not open. I received a error message saying safari can't open "firefox_sync-1.7-sm+fn+fx.xpi" because no available application can open it.

Firefox will not open after attempting to upgrade to v5, sys restore didn't help

Was running 3.6 with no problems, but trying to upgrade today apparently broke it. The upgrade failed for some reason (the old .exe is still the only one in the Firefox folder & I can't find any files newer than April 2010 in there), but no matter how I try to run it, nothing happens - Firefox will not open, period. I tried reverting to last week with sys restore, scanning for malware with Malwarebytes, but still nothing happens. I'm using WinXP 5.1 media edition SP2 (yes, it's been around a few years but it works for me). I'm now using Chrome which seems to run just fine, tho I miss all my plugins.

Hi lwhealon
try from Start > Run > and type to check 1 of :
firefox -safe-mode
"C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode '''or'''
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode
(to enable the Run box in win 7 see: [http://blogs.msdn.com/b/tims/archive/2006/09/18/windows-vista-secret-3-bringing-back-start-run.aspx enable Run box win 7] )
also check if [http://kb.mozillazine.org/Firewalls Firewall] or/and other security software blocking firefox start (like ad-blocker, web-accelerator etc).
[http://kb.mozillazine.org/Kill_application With Firefox completely closed] (probably because you can not start it), open the [http://kb.mozillazine.org/Installation_directory application folder] (by default, C:\Program Files\Mozilla Firefox on Windows) rename firefox.exe to firefox1.exe, then double-click firefox1.exe. If Firefox runs without problems, it could indicate that your firewall is blocking Firefox.
good luck

I was told I had to upgrade Firefox to 4.0, downloaded the dmg, launched it and now Firefox will not open at all.

I was told I had to upgrade Firefox to 4.0, downloaded the dmg, launched it and now Firefox will not open at all. It tells me "The operation can't be completed because you don't have permission to access some of the items." Also, that "Firefox cannot be opened because of a problem." And it give a bunch of code. This is my main browser. What is happening here? My OS X is 10.6.7. Has this caused a problem?

If you right-click on your Photoshope.exe, select Properties, there should be a Compatibility tab. There you can select Windows XP, Windows 2000, Winows 98 or 95. One of these should allow you to open Photoshop 6, unless you mean CS6.

After upgrading to 3.6.4 (english) firefox does not open

After upgrading to 3.6.4 (english) firefox does not open when I hit its button. I uninstalled it and reintalled it but the problem remains - My operating sys is VISTA 2 service pack. IE works
Any suggestions?
== Operating system ==
VISTA 2 service pack

I have been using Firefox on a regular basis for many years.
I have two problems with Firefox 3.6.4.
First, it keeps crashing....
I have 4gb of memory on a Windows 7 - HP Laptop and whenever Firefox tries to allocate more than 1.5gb of memory it crashes. What is more interesting is the fact that while Firefox is running on a static page; such, as the google search page...the memory allocation keeps climbing... Even when nothing else is running.....Does anyone see a problem with this. I have tried all the suggestions that I could search for and I have come to one conclusion....the problem is software related and software problems should be fixed with software not by people manually going into an application and toggling something on or off. In other words the mozilla team should be looking at trying to resolve this issue.
So, what programmer did you guys have write the 3.6.4 memory handler - a person who doesn't understand how to allocate and deallocate memory?
Just so you know what I have been describing above about Firefox 3.6.4 is a memory leak, and memory leaks are usually a first sign of poorly written code.
==
My Second Issue is in regards to the newest Firefox Update, which prevents me from going to the internet whenever it's installed because it has a flaw with its Network Proxy module. I have to re-install the original Firefox v3.6.4 to fix this problem.
Solution:
I'm going back to Internet Explorer because the mozilla team can't fix all these issues. I don't have the time to come up with a work around solutions for an inferior piece of software that is supposed to just allow me to browse the internet at anytime....

How can I get Firefox to automatically open a new search in a new tab please?

How can I get Firefox to automatically open a new search in a new tab please? [Without me manually opening the tab]

For searches from the Search Bar, when you use the Enter key.
Type '''about:config''' in the URL bar and hit Enter. 
''If you see the warning, you can confirm that you want to access that page.''
Pref = '''browser.search.openintab''' = double-click to toggle to '''true'''

One of my favorite things about developing for iOS using Xcode is the Simulator. It runs any of the iOS devices simulated right on your Mac. If you don't have a hardware device to test your application on, the Xcode simulator will surely be your best friend.
So to answer your question less vaguely, yes. You can own the iPhone 5s and develop for the 6. There is no real release information of the iPhone 6 at the time anyways, so I would not let it play too large of a factor in your decision.

Hey! I recently had to reboot my computer and reinstall itunes. I now want to update my iPad but it is not allowing me to save my apps in my itunes library because it is already connected with my old library from before I rebooted. What do I do?

Hey! I recently had to reboot my computer and reinstall itunes. I now want to update my iPad but it is not allowing me to save my apps in my itunes library because it is already connected with my old library from before I rebooted. What do i do?!

The solution is fairly easy IF the items that you are concerned about are all items that have been obtained from the iTunes Store AND they were all purchased using the same Apple ID. First, with the iPad disconnected from the computer, fire up iTunes. Look to the right side top and confirm that that Apple ID is displayed. If it is not, go to "Account" and log into that ID. Then, connect the iPad. Say "yes" to the "Transfer Purchases" choice. Everything on the iPad will be transferred to the computer's iTunes library.
If anything goes wrong, you can download all purchased items again with no charge (except movies) provided that you use the same Apple ID.
If you have been using multiple Apple IDs, it's a bit more complicated. Post back and we'll go from there.

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.
