When I try to open Firefox, Google say the ULR does not exist on the website?

I use Firefox and have the latest version. Currently when I try and open Firefox, Google posts and error message saying the 404 the ULR does not exist on the web. What do I need to do? In layman's terms please.

When I try to open firefox it says that it is not responding, after I disabled the adobe flash plug-in it worked, how do I get it to work with flash

Since I updated my adobe flash player firefox keeps saying that it is not responding after I open it and it loads my home page, I disabled add-ons and went throught the process of figuring out which one it was and it was adobe flash, but without flash I cant access a lot of different sites, how can I fix this. I have tried uninstalling and reinstalling both firefox and adobe flash, but neither works!

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.

I download itunes it says its successfully installed. then when i try to open it it says "apple application support not found" PLEASE HELP!!

I download itunes it says its successfully installed but then when i try to open it is says "Apple Application Support not found"

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, does iTunes launch properly now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

When I try and install firefox it says that I do not have the correct privaliges- MAcBook Pro.

When I try to update Firefox, it says that I do not have the correct privileges.

You can try to repair the permissions for the Firefox application files and folders.
You can also do this:
Download a new copy of the Firefox program: http://www.mozilla.com/firefox/all.html
Trash the current Firefox application to do a clean reinstall.
Install the new version that you have downloaded.
Your profile data is stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder], so you won't lose your bookmarks and other personal data.

Not using any mouse pad, I have a very smooth desktop. But I just tried to use a sheet of A4 printing paper, but no result, the problem persisted.
Someone on this forum suggested, that USB3 may interfere with the magic mouse.
I have 2 LaCie HDD's about 70 cm away from the mouse, I use them on Thunderbolt. But in operation or not - the result is the same, the mouse plays up! Just now I was clicking the desktop and the mouse created a new folder!!
Thanks for the advice, Bee
Cheers, Gerd

I just installed Adobe CreatePDF desktop printer, when I try to use from Word or Excel, it does not work. The Adobe print queue says "error" in the status screen. I have uninstalled and re-installed. Any ideas of what to do next?

I just installed Adobe CreatePDF desktop printer on a Windows 7 home PC. When I try to use from Word or EWxcel, it does not print. The Adobe print device queue reports an "error" in the status column.

Adobe retired this Feb 17, 2014.
This app sent content to and got content from the web based services of "CreatPDF" and "PDF Pack".
These are subscription services out in "the cloud". When the app was live you had to be online and signed into your account. The user forum for CreatePDF has a DOC that speaks to the app removal.
Be well...

There was a problem connecting to the server "Time Capsule". The share does not exist on the server. Please check the share name, and then try again.

The following error pop's up as an [OK] dialogue box after logging in the iMac,
There was a problem connecting to the server "Time Capsule".
The share does not exist on the server. Please check the share name, and then try again."
As it happens, a connection to the Time Capsule is established usually, anyway. On occasion it doesn't.
I have a Volume, Data, on the capsule, which similarly, usually mounts, but occassionally doesn't, with access permissions denied.
Any suggestions on how begin to work out how to achieve networking seamlesness?

First, restart the Time Capsule by disconnecting the power adapter and reconnecting it. If other devices on the network can see it, you can skip this step.
From the menu bar, select
 ▹ System Preferences ▹ Network
Click the lock icon in the lower left corner of the window and authenticate to unlock the settings, if necessary. Click the Advanced button, then select the TCP/IP tab in the sheet that drops down. Click Renew DHCP lease.
Try again to back up.
If you still can't, open the Time Machine preference pane and delete the TC from the list of backup destinations. You may have to unlock the settings by clicking the lock icon in order to do this. Then add it back.

When I try to open firefox it says an update is ready to apply, but when I click ok it says it can not because firefox is already running.

When I double click Firefox it says an update is ready to be applied. Would you like to apply it now? I click yes and a green bar starts to fill, at about 3/4 it beeps twice it says it could not be completed because another instance of Firefox is already running, please close it and retry. However, the only program my task-manager shows is the update.

Did you check the Processes tab in the Task Manager?<br />
You may also have other (security) software that is having a file handle open on some of the files.<br />
In that case you may need to download the full version and delete the Firefox program folder before installing that downloaded update.
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* 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.

When I try to open Firefox, it says that "the proxy server is refusing connections." What settings do I need to change? Even though the internet signal is strong, I can't open any webpages.

It also says that Windows cannot connect to the Internet using HTTP, HTTPS or FTP. This is probably caused by Firewall settings on this computers. Check the firewall settings for HTTP port (80), HTPPS prot (443) & FTP port (21).
This all started when I tried to tried to delete the Verizon Broadband toolbar and home page that always opened when I opened Firefox.

In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings".
See "Firefox connection settings" in [[Server not found]]
You can find the connection settings in "Tools > Options > Advanced : Network : Connection"<br />
If you do not need to use a proxy to connect to internet then select No Proxy

When I try to open firefox, it says that a session is already running and I need to close it before I can run another session, I cannot find the session that's running, what can I do?

This happens after I have used firefox and exited the program. When I try to reuse the program I get this message. Is there a setting within firefox causing this or ??? I have tried to locate the session running without any luck. Would appreciate any help. I have uninstalled the program and then reinstalled it, but nothing has changed it continues to malfunction.
