Try updating your Firefox to the latest version. Here is where you can download it:

If it does not help, then you may need to reinstall Mozilla Firefox from your computer by removing the existing one first before installing the new version again.

This could happen after your netbook crashed or turned off while Firefox was still running. When Firefox is running, it puts a file called "parent.lock" in your Firefox profile directory. If you delete that file, Firefox should start properly again.

I'm not sure exacly where the profile directory is on your system (I currently don't use Linpus Lite anymore), but it should be somewhere in your home directory in .firefox or .mozilla. Maybe this page could help you find it.

If you didn't have the problem before yesterday you may want to try Windows System Restore before you do a full frest install.

Choose a date from before the problem existed.
Try to install a newer version of firefox.
This is a common problem with Firefox and the solution is also simple.
1. First go to Task Manager and end process “firefox.exe”.
2. Go to programs -> Mozilla Firefox -> Firefox (safe mode)
3. In the check list select for defaults and disable all add-ons.
4. Click make the changes and restart.
Scan ur pc with maleware.
The another solution is
· Go to 'Run' and open 'cmd'
· Type 'netsh' in command console then press enter
· Then type 'winsock' and press enter and then type reset
· Restart Your PC

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.but I have no Firefox window open what should i do?


HIt cntrl alt delete to open task manager (or right click on the taskbar) and look at the processes running. You will find Firefox is running although you dont currently have the browser window open. Click on Firefox in the task manager and close it out. Then close the task manager and you'll be able to open Firefox again. This is a common problem with Firefox. It happens in IE as well but for some reason, you can still open IE.
Hope this settles your problem. All the best!
