There's something I don't like about ff 3.5.
You see, I usually copy a tab by dragging while holding Ctrl. This is useful when you don't want to leave a page but want to do something else on the same site, for example a search.
I suppose there are other ways to do that, but I was comfortable copying tabs the way I mentioned and now it's gone!
I'm sure that somebody knows how to fix it.
Thanks for your support.
