Okay, I will try notice the developer of 'Tree Style Tabs' about the problem. Thanks.

This review is for a previous version of the add-on (2.4.5.1-signed).

Is it possible to reuse the original open action? This way, 'Tree style tabs' might be able to track it as a child tab, may be you should install 'Tree style tabs'(it is really a great plugin which improves productivity), and do some tests.

What original action? In any case, wouldn't it make more sense to tell the 'Tree style tabs' author to fix his extension rather than everyone else making workarounds for it? :-)

Btw, there is a Support Site for these kind of discussions.

Does not working well with "Tree style tabs", after clean the links of google search resulets, the tab is no longer opened as a child tab, even though I love this addon over other similar addons, I have to disable it.

This extension uses the Firefox's internal function openUILink(). So, i think whatever issue you're experiencing with "Tree style tabs" you'll notice it as well with any other extension or the browser itself when opening links using the mentioned function.
