no success Rated 1 out of 5 stars

Tabs, which opened by other extensions, placed at the end, but not directly after a current tab.
In addition, my bookmarklets opens tabs in current tab when trying to open new window (before the installation of your extension they was opened as relative tabs directly after the current). So, I uninstall your extension (which have not options).
It work bad...
