Firefox not closing and subsequently not starting properly

Very often I cant start Firefox and I can only do so when i close all Firefox processes manually in taskmanager.

Correction...I've just turned on my computer and the same thing happened the first time i started FF. lol technically my question summary is wrong. I have disabled multithreading(by running in Win ME compatibility) and firefox doesnt even open...it just crashes.

When I started my PC this morning I got a pop-up message stating that CC has damaged files and required downloading from www.adobe.com/go/adobecreativecloudapp. Indeed, CC did NOT work and subsequent attempts to download CC never got beyond the initial installer box. The posted link also appears to be bogus I am at my wits end here. Have other users experiences this issue? Is this a clever intrusion?

Firefox is frozen and will not close but I want to un-install it. HELP!

Firefox was open and an error message. Unresponsive script running, continue or stop script? All options were frozen I was not able and still not able to close firefox or any tabs from it, it has been frozen for two days. Is there an easy command line to just close the application?

You can close Firefox through the Terminal if it refuses to close through Firefox > Quit<br>
You can open the Terminal by searching for it on the Spotlight (top right corner, magifying glass)
Once open, you can run this command to kill the Firefox process:
*kill -9 $(ps -x | grep firefox)
I'm not a Mac user but that command works for me in Ubuntu.
To figure out what's causing the unresponsiveness, you can try to start Firefox in Safe Mode. To start Firefox in Safe Mode, just do the following:
*Clikc the Help menu on the menu bar and select Restart with Add-ons disabled.
*Click Start in Safe Mode to the dialogue box that comes up.
Safe Mode disables the following:
*Extensions
*Default theme is used
*userChrome.css and userContent.css files are ignored
*default toolbar is used
*Hardware acceleration is disabled.

K900 closed and will not open

k900 closed and will not open I do not get any message when I connect the charger . In the same way there is no response from the phone to the computer bağladığımda problem. What should I do . turkey over the phone , no one has information about I would appreciate if you can help

I started having the same problem after updating to IOS 8.3 on my IPhone 6. Phone keeps shutting down and the only way to open again is to hold both the home and sleep button. Being plugged into the charger makes no difference nor does the level of charge. Has never happened until today after the update, just randomly shuts down while wearing it on my hip. All apps seem to work fine while it is on. I might need to return to IOS 8.2 if this continues to be an issue. Has not done it while in use yet.

Ever since the most recent firefox update, every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it?

Every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it? When I restart firefox, then the download continues and all is well until I try to download something new (which I do quite often).

You may well find this article of interest and help in sorting out your problems: [[Installing a previous version of Firefox]] The article does contain a link for previous versions, but also points out other troubleshooting advice that may be more appropriate in some instances.
Another useful article is [[Basic Troubleshooting]]
I hope you sort out your problems either by downgrading or finding the cause of the problem.

Firefox failed today and will not reinstall nor run in any way

FF stopped working entirely. I uninsalled 13 and reinstalled 14.0.1. That did not solve the problem. I get msg that FF is already running but it is not running and does not show up in the Task Manager as an active process. Scan of machine for viruses using PrevX shows a clean machine. I have tried many of the ideas in this support web site but am limited since I have no ability to run FF. Resetting Profiles folder from Read-Only to not Read-Only did not hold as every time I checked the Profiles folder properties it is always resetting itself to Read-Only.

You probably see a green square, but not the check mark in the Read-only box.<br />
The green square doesn't have a meaning as Windows always shows that by default for a folder.
Do you still have the default profile as listed in the profiles.ini file as Default=1?

Why when I tried to update itunes it crashed and now I get a MSVCR80.dll was not found and can not start my itunes any more

Why when I tried to update itunes it crashed and now I get a MSVCR80.dll was not found and can not start my itunes any more?

Solving the iTunes Installation Problems in Windows
1. Apple has posted their solution here: iTunes 11.1.4 for Windows- Unable to install or open - MSVCR80 issue.
2. If the Apple article does not fully resolve the problem for you, then try Troubleshooting issues with iTunes for Windows updates - MSVCR80.

Had to have my hard drive rebuilt in my PC (not Mac). When I reinstalled my music library from iTunes, several of the songs did not download properly - they appear in light colored ink on my library list but the songs will not play and will not synch

Had to have my hard drive rebuilt in my PC (not a Mac). When I reinstalled my music library from itunes, some of the songs did not properly download. They appear in light colored ink, but will not play and will not synch with my iPod. How can I get all of my songs back?

If your country's iTunes Store allows you to redownload purchased tracks, I'd delete your current copies of the dodgy tracks and try redownloading fresh copies. For instructions, see the following document:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
Otherwise, I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the items that are not playing properly. If you can't see "Report a Problem" next to the items, click the "Report a problem" button. Now click the "Report a Problem" links next to the items.

Firefox is not opening and is NOT present in task manager

With no apparent reason FF is not opening and is not present in Win Task Manager. I tried to reinstal, reset registry and other common solutions but none of them changed anything. After doubleclick on an icon nothing happens... and thats all.

For some reason it is ok now after I've installed FF 3.0.6 and then made an update to 3.6.

"This cable is not certified and may not work properly..." Official Apple cable!

I am using an official Apple charging cable and keep getting the message "This cable is not certified and may not work reliably..." And this cable has worked until now! Restarting the phone works sometimes but only for a bit.
What's wrong here/

Thanks, but it didn't fix it. I've tried 3 different Apple cables and I get the same message with each. I'm guessing it's the port has become defective somehow although with all the other questions about the same issue, I wonder if it could be a software issue!

The URL is not valid and can not be loaded in excite home page

Windows 7 64bit. New HP computer. I loaded firefox and use excite as my homepage. When excite comes up the page loads and about 7 or 8 seconds later a pop up appears with "The URL is not valid and can not be loaded" on it. I can't figure out what URL is not valid. It does it every time I refresh or come back to the homepage. It just did it again as I type this.
Can anyone help?

Is not abstract and does not override abstract method tablechanged

I will remove all the gui code to make it shorter, but my problem lies with my InteractiveTableModelListener.
public class Meet extends JPanel{
private static void createAndShowGUI() {
        JFrame frame = new JFrame("MEET_dataTable");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new Meet(), BorderLayout.CENTER);
        frame.pack();
        frame.setVisible(true);
public class InteractiveTableModelListener implements TableModelListener {
     public void TableChanged(TableModelEvent evt) {
if (evt.getType() == TableModelEvent.UPDATE) {
      int column = evt.getColumn();
      int row = evt.getFirstRow();
      dataTable.setColumnSelectionInterval(column + 1, column + 1);
      dataTable.setRowSelectionInterval(row, row);
class InteractiveRenderer extends DefaultTableCellRenderer {
protected int interactiveColumn;
public InteractiveRenderer(int interactiveColumn) {
      this.interactiveColumn = interactiveColumn;
public Component getTableCellRendererComponent(JTable dataTable,
     Object value, boolean isSelected, boolean hasFocus, int row,
     int column)
Component c = super.getTableCellRendererComponent(dataTable, value, isSelected, hasFocus, row, column);
   if (column == interactiveColumn && hasFocus) {
     if ((Meet.this.tableModel.getRowCount() - 1) == row &&
        !Meet.this.tableModel.hasEmptyRow())
         Meet.this.tableModel.addEmptyRow();
    highlightLastRow(row);
return c;
public void highlightLastRow(int row) {
     int lastrow = tableModel.getRowCount();
if (row == lastrow - 1) {
      dataTable.setRowSelectionInterval(lastrow - 1, lastrow - 1);
else {
      dataTable.setRowSelectionInterval(row + 1, row + 1);
     dataTable.setColumnSelectionInterval(0, 0);
public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
            UIManager.put("swing.boldMetal", Boolean.FALSE);
            createAndShowGUI();
}As i say, i have removed all the gui code to make it shorter, but in this code i create the table and add all the model to it. I am being returned with the error
Meet.InteractiveTableModelListener is not abstract and does not override abstract method tableChanged(javax.swing.event.TableModelEvent)in javax.swing.event.TableModelListener
what would be causing this error?
Cheers

Sorry, just figured out my silly error, the method is tableChanged not TableChanged.
cheers

Is not abstract and does not override abstract method ERROR

Hello. I'm new at all this, and am attempting to recreate a sample code out of my book (Teach Yourself XML in 24 Hours), and I keep getting an error. I appriciate any help.
This is the Error that I get:
DocumentPrinter is not abstract and does not override abstract method skippedEntity(java.lang.String) in org.xml.sax.ContentHandler
public class DocumentPrinter implements ContentHandler, ErrorHandler
        ^This is the sourcecode:

   if (args.length == 0)
     System.out.println("No XML document path specified.");
     System.exit(1);
   // Create a new instance of the DocumentPrinter class.
   DocumentPrinter dp = new DocumentPrinter();
   try
     // Create a new instance of the XML Parser.
     XMLReader parser = (XMLReader)Class.forName(PARSER_NAME).newInstance();
     // Set the parser's content handler
    // parser.setContentHandler(dp);

     parser.setErrorHandler(dp);
     // Parse the file named in the argument
     parser.parse(args[0]);
   catch (Exception ex)
     System.out.println(ex.getMessage());
     ex.printStackTrace();

System.out.println("End of Document.");

public void fatalError(SAXParseException exception)
System.out.println("Fatal parsing error on line " + exception.getLineNumber());
public void warning(SAXParseException exception)
System.out.println("Warning on line " + exception.getLineNumber());

Check to make sure that the arguments are consistent with your ContentHandler class. Probably the wrong type.
I think you forgot to include the skippedEntity method, it seems to be missing. Even if an implemented class has a method that you are not using, you still have to include the method in your code even if it doesn't do anything.
