...hmmm I haven't figure out how to cut and paste with my tablet. 
Oops! Sorry 'bout that! If you can see the address bar, if you tap on it, and highlight the entire thing, you might bet a context menu prompt that allows you to copy the entire thing, and then you can paste it into the text box on the TBR page?
I don't use a tablet, but I can use the same procedure on my phone, so perhaps it would work on a tablet.
