Version 1.2 NOT WORKED under FireFox 3.6.23. Bookmarks always opened at the end of the tabbar.

It works perfectly in every version up to the latest (8 at the time of writing) as long as you set your preferences and about:config flags correctly. Also make sure you don't have other extensions that could conflict.

As an experiment make a new profile, install just this extension and set it up as I describe in the description. It will work as advertised. Then you can figure out what you did to break it on your main profile.

Or how about this: stop moaning and fix it yourself. The source code is available. That is what I did when I created Tabs Open Relative (modified) - I fixed Tabs Open Relative instead of just complaining about it.

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...
