When I try to open firefox it pops up, "do you want to allow changes to your hard drive" everytime

Firefox update while I was trying to resolve a issue with a brother fax drive to update for windows 7, now every time I go to firefox it pops up, "Do you want to allow changes on your hard drive" as if it didn't finish, so I answer "yes", firefox browser comes up, but if I get out and go back in it does the same thing.
in the pop up window is listed; C:\program file(x86)Mozilla firefox\firefox.exe
But when I search it, nothing

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.
You also need to check the Properties of the firefox.exe program in the Firefox program directory.
If you can't make the changes then you need to start Windows Explorer as Administrator.

When I try to open Firefox, MSN pops up even after I specified Firefox as my default browser. HELP!

I downloaded a VIAO update, now can't open Firefox. When I try to open Firefox, MSN opens in HTML. I access my mail from I.E. I've also had problems with my facebook page. Ran virus scan and Malwarebytes. All my bookmarks and favorites are on Firefox.

When I try to install Firefox, windows asks me if I want to allow this program to make changes to my computer and then nothing happens whether I say yes or no?

Question is asked by "user account control"

Even if you are logged on with an Administrator account then you should still not run Firefox with Administrator permissions.<br />
I would assume that is already installed, but if this is happening when you try to install Firefox then you need to right-click the Firefox installer and choose Run as Administrator to make sure to get the proper permissions to install the Firefox program and create the required registry keys.<br />
Then you need to confirm that you want to install the program.<br />
If Windows blocks the file because it is downloaded from internet then open the Properties via the right-click context menu and check the Security tab.

Can't open Firefox. When I try to open, a window pops saying "Close Firefox" and "A copy of Firefox is already open. Only one copy of Firefox can be open at a time.", and doesn't allow the application to open.

Came home to find computer restarted, which I assume is an automatic Firefox update.
When I try to open Firefox, window pops up saying "Close Firefox" and, "A copy of Firefox is already open. Only one copy of Firefox can be open at a time."
I'm unable to open the program at this time, lots of critical work info stored there - please help. Thx.

After restarting my computer firefox is deleted for Windows, when i try to open firefox a message pops up saying the program has been moved from its original location and is unable to run How do I get Firefox on my computer permanently?

After restarting my computer firefox is deleted for Windows, when i try to open firefox a message pops up saying the program has been moved from its original location and is unable to run How do I get Firefox on my computer permanently?

I have tried everything I could to fix this, but some things require actually being on Firefox, and since I cannot get on, I cannot click on the tabs to do it. I have even totally uninstalled firefox, and that has not fixed this. I still get the same message that firefox is running and I need to close it or restart (which I have also tried dozens of times). I have removed things like Java, and that has not helped either. If I cannot even get on line in firefox, how can I fix this. I am not crazy about using internet explorer, but right now, it is my only option. I even tried to start in safe mode, and the same message box pops up!

A program called "tudosearch" interferes with my Firefox - it always comes up when I try to open Firefox or if Firefox tries to call up another program. I can not find a way to get rid of it.

When I try to open Firefox, a window comes up saying that Firefox can not run Tudosearch. I then have to exit this window before I can go on. It also comes up when I try to go to another website while in
Firefox. I can not find the program "Tudosearch" on my computer therefore I can not remove it. Any suggestions?

I downloaded Firefox 4 onto my PowerPC G4 1.67GHz running Mac OSX 10.5.6. When I try to open it I get error message You cannot open the application "Firefox" because it is not supported on this architecture. I can't find my Firefox 3.6.16 I'm on Safari.

Use Tony's suggestion. I am running it right now and it is awesome. I love Mozilla but they basically screwed all of those older Macs over. Come on Mozilla. These Macs still work, and there are plenty of people with them out there.

Error when I try to open Firefox. Says Firefox is running in the background and cannot open. Suggests closing that window or restart system. This has happened several times recently. I reinstalled but am still getting the error. Any thoughts?

I am getting an Error when I try to open Firefox that Says Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system. This has happened several times recently. I deinstalld and reinstalled but am still getting the error. Any thoughts?

This happens to me as well. However, I have a shortcut on my desktop as well as my quick start bar. When this has happened to me, I can usually log back in without restarting, by using the shortcut on the desktop rather than the usual quick start bar.
I know this sounds weird, but it has worked for me about 80% of the time.

WhenI close firefox, and later when I try to open firefox again, it says it is already open, although it shows to be closed---don't know when it is closed or not, don't like this

When I close firefox, it closes, then later when I try to open firefox again a message opens and says firefox is already running, ---have to open task manager to close firefox before it will open again, browser may have been open for hours and didn't show to be---why does this happen, don't know when firefox closes or not------

The user-agent detection was incorrectly identifying FF4 as a mobile browser, in turn redirecting to a mobile version. Install the following addon to workaround this problem until it's fixed: https://addons.mozilla.org/en-us/firefox/addon/xhtml-mobile-profile/
