I tried to download a form and a window popped up

Hi there,

Try to reinstall Firefox, simply try to install it over the corrupt one.

If it not helps then

Try to remove/uninstall firefox, in add and remove programs (control panel), reboot the computer and install firefox again.

IF it not helps

Try to run chkdsk, you find it whne you highlight your (normally) C: drive and right click on it and choose properties- there you select the second tab and choose check this drive for errors-- check all the possibilities and reboot the computer and wait for the program testing your harddrive. After you can try your firefox again

OR

You can try to go to this firefox forum and ask the same question:

IF Not then return here
