normally I'd say thats a memory problem - however never seen this problem with firefox before...

uninstall the program from your control panel

then restart the computer

using internet explorer download the newer version of firefox from here

www.firefox.com

install the newer version and then try it again - if thats not working look at your RAM modules - they might be faulty as the Chipset can become damaged... thus causing your problem

Well, something like that is typically the result of a programming bug (in the programming world we would call it 'dereferencing a null pointer'). This isn't all that useful to the user however.

What you can do is -- try again, maybe the site you were on caused problems and tickled a bug inside Firefox.

-- Disable addons / plugins you don't need

-- Make sure your firefox is up to date (if you're using Firefox 2, you should upgrade to FF3).

-- Try reinstalling perhaps, if these don't solve it?

If you can, run the bug reporting tool that Firefox comes with. If it is a problem with Firefox and not something on your end (plugins / addons or what not) someone may be able to correct it.

This is a program error.

The program needed data to continue and was unable to find it.

This usually causes the program to stop or crash.

Normally you will get an option to click to terminate the program or in worst case, a blue screen.
