I cannot open Firefox as I get the message that Firefox failed to read configuration file. I uninstalled and reinstalled latest version and still cannot open with the same error.

Last week when the automated upgrade came I said yes and then stopped it midway as it was not a good time to reboot my laptop. Since then, when I try to open it says cannot read configuration file - even when I uninstall and reinstall - still cannot open it with the same error.

Do a clean (re-)install:
* 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
* 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.

Make sure anti-virus and other security software is disabled.
Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
These errors typically occur when security software interferes with the restore and update process. Use the steps to troubleshoot security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See the steps under the heading "Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store." If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

Downloaded 4.0 version now I have no firefox since I get a message that Firefox is not supported by my system

I tried to upgrade my firefox software to the 3.16 version and then the 4.0.
Upgraded due to getting lots of error messages with older version such as banking or transactions sites. Lost without firefox working to open sites.

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com

Does anyone know how to fix this problem?

you probably have an incomplete/corrupt download.
to confirm check the file size against the expected file size.
then re-download perhaps with a different browser.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.<br /><br />
NOTE: Establish a habit of exiting/closing Firefox with Firefox button > Exit or File > Exit to allow an orderly shutdown of Firefox and closing of all of the files that Firefox has open.

When I open Firefox I get a message that says I am working offline. I have tried reinstalling, but no help. Other acounts on this computer can get to Firefox, but not me. What's wrong?

I upgraded to the newest version of Firefox yesterday. But now I cannot get online with Firefox. I can check my e-mail and browse the web on Internet Explorer, but not Firefox. I get a message that says Firefox is working offline. I uninstalled and reinstalled Firefox, but that did not help. I restored my computer to Sunday's settings, but that did not help.

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!

I saved a Pages doc yesterday and today I can't open it because I get a message that says "can't open doc because an index.xml file is missing." Help!

Pages v5 documents do not have an internal index.xml file. When you attempt to open one of these with the older Pages '09, you will get that dialog. Double-click the document icon, or right-click, and open with Pages v5 to access the document contents.

is this normal, and how do i fix it?

can you try restarting Firefox in safe mode.

Keep getting a message that firefox is outdated but when trying to update the download is the same version in mac os

keep getting a message that firefox is outdated but when trying to update the download is the same version on mac os. The version is 34.0.5 .As soon as I launch the brwswer i get the update message.

hello dbajayo, your useragent (the information the browser sends to websites to identify its version) - apparently mistakenly - shows you're on firefox version 3.6.
probably some sort of toolbar or adware has overwritten it. please refer to this article in order to reset the user-agent settings in firefox: [[Websites say that Firefox is outdated or incompatible even though it's the latest version]]

When attempting to open email I repeatedly get a message that my username or password is incorrect. I have tried everything to reconcile including deleting and reopening the account however nothing has worked.

When attempting to open email I repeatedly get a message that my username or password is incorrect. I have tried everything to reconcile including deleting and reopening the account however nothing has worked. Any suggestions?

If it is a POP account, there could be an issue with the outgoing server setting. It will not hurt to check this and make sure. Make sure that your username and password are in there.
Settings>Mail, Contacts, Calendars>Your email account>Account>Outgoing mail server - tap the server name next to SMTP and check in the primary server and make sure your username and password are entered and correct - even if it says that the password is optional.

When I use a GSI external antenna for WiFi I first get a message that "Firefox is already running but not responding etc", and then Firefox crashes. Can anyone help please?

Because of weak WiFi signal I need to use an external antenna (GSI USB wireless WIFI long range network adapter). My computer can see the signal clearly and shows that I am connected to the right network. But when I try to launch Firefox I get a message that "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." When I click "OK" Firefox tries to load websites but gives up and reports "Problem Loading". It looks like Firefox is having trouble "seeing" the signal from the external antenna. What do I need to do please?

Try Ubuntu support, I don't think your problem is with Firefox - it will use the connection that the Operating System "makes". I'm a real noob with Ubuntu myself, and don't think I can help you figure out the problem.

When I close Firefox, then later want to start up again, I get I message that Firefox is still running. With "START TASK MANAGER", I need to close Firefox in order to start again.

I have the same problem. Firefox won't unload regardless of how long I wait. Literally hours ... I must go in and 'end the process'. This has been a real hassle for a while now. Even considered giving up on firefox. Please look into this! An additional problem; I have to run firefox to get the updates, but I can't get the updates to take because I can't get firefox to unload so I can restart it.

I cannot open Firefox as I get the message that Firefox failed to read configuration file. I uninstalled and reinstalled latest version and still cannot open with the same error.
