I have tried to download and install firefox several times. I have used different links to get to the download. Each time it downloads to 99% and then stops. When I click 'resume' I get the message: The signature of Firefox Setup 28.0 exe is corrupt or invalid.

Valitud lahendus

This usually happens if your security software is blocking the download.

It is possible that anti-virus software is corrupting downloaded files or is interfering otherwise.

Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

See:


Download and save the full Firefox installer to the desktop and start the installation with a double-click on the desktop icon.

You can find the full version of the current Firefox 28.0 release in all languages and for all Operating Systems here:
