It is about effing time!
I have been using tree-style tabs for years – can’t imagine using a browser without them. (although, it does make it too easy to have a billion tabs open at once)
Edit: the test pilot “side tabs” is working fine on FF developer v48
It would be nice if it did expandable sub-tabs like the tree-style tabs (and if I could put it on the right side).
Just noticed an issue as I went to save my edit… It cuts the bottom xhundred pixels off of the page, so I couldn’t see the “save edit” button. I had to disable the “tab center” in order to finish this edit.
