I have a ton of tabs open on my iphone and was looking for an easy way to clean them up. I have everything synced up between my macbook and my iphone. Is there a way to close tabs on my iphone from my macbook? Going through all of the sidebar tabs on a big screen is so much quicker but I'm not seeing a way to close tabs across all devices. Any advice would be great. If this isn't possible, this would be a great feature to have added to firefox. Thanks.
