From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0.0) Gecko/20020530 BuildID: 2002053012 I open a link in window opend by JavaScript without any bar userbase = window.open('../ub_detail.asp?id=' + id,'userbase' + id,'width=600,height=500,toolbar=no,menubar=no,location=no,scrollbars=yes,resizable=yes'); I open a second page as tab in it (by using right mouse-button over the link and selecting "Open link in new tab"). The page will be opened, but I do not get a tab-slider (I hope it is called like this?) so that I can switch between the different tabs. Reproducible: Always Steps to Reproduce: 1. open a new window with JS, e.g. userbase = window.open('../ub_detail.asp?id=' + id,'userbase' + id,'width=600,height=500,toolbar=no,menubar=no,location=no,scrollbars=yes,resizable=yes'); 2. open a link displaied in this window as tab using right mouse menu "Open link in new tab" Actual Results: No tab-slider to switch between different tabs. Expected Results: A tab-slider for every window I open as tab. In some of the previous betas I used to have the tab-sliders as expected. I do not know since when this does not work anymore...

Problem still present...

This bug still exists in 2003030704... It is very annoying because I am not able to open tabs in any kind of popup-window. Either tabs should NOT work in popups or they should be shown as it worked already before this bug was introduced...

Can you attach a small testcase ?

Yes... ASAP...

I have also found this issue to be an inconvenience. Since no testcase has yet been provided, I made a demonstration that is available at http://www.hut.fi/u/tsknorri/mozilla/popup_tab.html . While looking for a minimal test case I came to the conclusion that the tab-slider is missing from pop-up windows when both 'toolbar=no' and 'location=no' have been used in the window features (third parameter to the window.open() function call).

Sebastion, tnx for your help. I really forgot to take care about this issue!

dup of bug 143866 I'll transfer some of the knowledge collected here to the other bug. *** This bug has been marked as a duplicate of 143866 ***
