Does "same tab" mean "same url tab" ?
So, how is "Move to an already opened tab" addon.
https://addons.mozilla.org/ja/firefox/addon/move-to-an-already-opened-tab/
This addon prevents to open same url.
thx.
-------------
OK, I add "Close same URL" in version 2.12.
But, Firefox for Android has a bag, so this often does not work well . (╥﹏╥)
