So Timmy said there was no way of closing multiple tabs at once on my mobile phone. I thought "There must be" but couldn't find a way but Timmy looking thru the links I had got looking suddenly said "Ah, yes, click on the number of tabs number then click the dots at the top of the screen and then click 'Close All'"
Duh, between the two of us we couldn't find owt but we did it together in the end
