"Position new tabs to right of current tab" option can be improved

[lebedev]

It is possible to use about:config preference browser.tabs.insertRelatedAfterCurrent instead of custom one for this option. However, browser.tabs.insertRelatedAfterCurrent doesn't affect new tab position: it opens at the end of the tabs bar. So maybe there should be another option "Open blank tabs after current"? Like this:

• [x] Insert related tabs after current tab (enabled by default)
  • [x] In a left-to-right group (enabled by default)
  • [x] Open blank tabs after current as well (enabled by default)

And that new option should be localized somehow.

It would be nice, like in Opera.

I discovered how Firefox decides where to put a tab (if browser.tabs.insertRelatedAfterCurrent is true) - if a tab has owner property (meaning that tab was opened from another tab), Firefox puts it after current, if not (blank tabs of tabs opened from history/bookmarks) - it places it at the end of tabs bar.

EDIT: it's vice versa with owner property actually.
