I was trying to get ITV live earlier on my computer but the bastads don't support Firefox.
They do however recommend a workaround which is called ietab -
http://ietab.mozdev.org/ - so I tried it out.
If you install this add-on, you can, amazingly, open an Internet Explorer tab in Firefox or even switch between browsers on the fly without changing tabs.
OK, it's still IE you are browsing with, with all its drawbacks and dangers, but at least you don't have to fire up a new browser and drill down to the page you want all over again.
It works perfectly and allowed me to get all the Pools World thingies that only sometimes work with Firefox. The disadvantage is it also enabled me to watch X-factor.
A great add-on to be recommended.
