I have only just started to use Firefox as I got very tired of IE. I watch a lot of flash/flv videos on many different sites and sometimes like to download some of these (which I could do on IE but couldn't here). I downloaded the add on "download helper" which was great and worked really well and easily but all of a sudden it now no longer works (the icon is still there but it won't recognise any type of video form any site at all - and I have no idea at all how to repair/fix it. I am not a PC expert or guru so any kind of easy step by step help will be greatly appreciated (I don't want to have to go back to the horrible IE please!!!!!)
