When I open a link in a new tab the browser's focus switches to the tab right beside the one in current use more often than it does the one just opened. I would much prefer it to not switch to tabs automatically unless it is a blank tab being opened. The option "When I open a link in a new tab, switch to it immediately" unchecked, yet it still switches to the tab right beside [adjacent] the current one, even if the newly opened tab is ten tabs away. It will stop for a while if I turn it on, save, then turn it back off, but returns after Firefox has been closed and reopened.
