Install this add-on: https://addons.mozilla.org/en-US/firefox/addon/jquery/

how will that help?!

should i tell every client that they need to install this to get their site to work? and then tell them to tell every customer to install it if they'd like to use their site?

I can just use another browser to develop on and see it working. Just flagging a problem... it is quite a major problem if this is to do with the upgrade. I need it to work without installing any add-ons

Hi,

I had the same issue. If you are calling

$( "#tabs" ).tabs();

in Ready function, firefox does not show the tabs. Works inside the ready function in both IE and chrome.

Moved it outside ready function and it solved the issue for me. (in Jquery 1.5.1 and 1.6.1)

Move it outside will break on FF3, IE ...etc...

I think they have fixed it.... I just got a fresh install and it worked without needing to change anything?!

I have it in the $(document).ready(function(){ $('.tabs').tabs(); });

and works?! very strange. thanks for all the replies though. Much appreciated.
