hello, it is possible to copy the url while you're on a page (before you tap the url-bar) by long-pressing on the page title/address...

Ah, that does work. Thank you!

I actually went ahead and installed the Firefox Aurora build (pre-Beta), and I found that they have implemented the same copy and paste toolbar that is found in Chrome, so I guess all we have to do is wait a couple more releases and it'll be baked into the regular Firefox for Android browser. Your solution works well in the meantime for anyone who doesn't want to use Aurora, though. Thanks again!
