No problems here with installing the Alexa Toolbar for Firefox. Maybe your security software is blocking it.

Try to save the file via the right-click context menu.


It is possible that (anti-virus) security software is causing the problem. Try to disable security software temporarily to see if that makes a difference.

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?
