Thank you, Yuki and Jasonliul.

There are 3 sentences not translated correctly from my opinion.Please check it out.
1.Background tab for new tab(現在のタブ)
It means if the hyperlink is intended to be opened in a new tab, then the new tab should be a new background tab.If it is intended to be opened in current tab, then let it be in current tab.
2.Close current tab and activate opener tab(現在のタブを閉じて新しいタブを開く)
The opener tab means "parent tab", referring to the tab that this tab opened from.
3.Activate opener tab(新しいタブを開く)
The same reason as above.
