That is a problem with the JQuery script in Firefox:

• http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.6.min.js

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.
* Please contact the website owners to inform them of this problem.

Hello, Tried the link you gave, but have a "link not found" with a suggestion to check syntaxe of the link given. Any other idea of how to process? Thanks, Nathalie

Sorry, tried again without the cap in the link and got the message of over 90000 characters, so can't post it here. Any suggestion? Thanks, Nathalie

There is a problem with that file on the server indicating that the file is either corrupted or is using a (gzip) encoding that Firefox doesn't support and that prevent Firefox from running the JavaScript to hide that content.
I sometimes see a short Flash of the first part of the file that is replaced with the error message. If I disable compression then I see corrupted text that also has repeated sections.
Google Chrome doesn't give an error, but shows text that doesn't make sense (the link doesn't work there as well).

You need to contact the http://ajax.aspnetcdn.com site and ask them to replace the corrupted file and for now try a different version from another link.

It should look like this code:

• http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js

It works if I paste the code from that site in the location bar with the comment at the start removed and preceded by javascript:

javascript:(function(a,b){function cu(a){return f.isWindow(a) <etc.>
