And after it if I continue clicking on the tab close button, I will close a page but the corresponding tab will not disappear. So I end up with more tabs than pages, with some tabs that can never be closed. I experience this problem in Nov 29's official nightly win32 build, and all builds from aebrahim and cypher77 (refer to the Firebird build forum on MozillaZine.org) after Nov 19. At least one person confirmed this. And some one said about similar problem they ever had. Reproducible: Always Steps to Reproduce: 1. Open 3 or more tabs using Ctrl-T or what ever way you like 2. Switch to one of the tabs in the middle and let it go to http://software.yalaso.net/ 3. Close this tab Actual Results: None of the rest tabs will get the focus. If continue cloing tabs without clicking any tabs to give them focus, the browser will end up with more tabs than actual pages displaying. And the spare tabs with no pages associated cannot be closed until closing the whole browser. Expected Results: The next tab should get the focus. And no problem when closing more tabs.

That's odd... The problem appears at that site, but not others. Its body tag has onunload=sethome(), but sethome() isn't defined anywhere. I'm guessing this might have to do with the problem. Confirming on Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6b) Gecko/20031130 Firebird/0.7+. It works in Seamonkey 2003112008.

Yes, your analysis seems correct. I made up a page by myself, and in the <body> tag I added onunload="nonexist()", where the javascript function nonexist() does not exist. So the body tag looks like <body onunload="nonexist()">. I tested this page with Firebird and I got the same result as the odd website. So now I think probably the problem is due to the javascript error at the time of closing the tab.
Summary: Multi-tab browsing: No tab get focus after closing a tab displaying some particular web pages → No tab gets focus if tabbed page with body onunload=nonexistantfunction() is closed
Is this still an issue?
Nope. Marking WFM.
