The only left tab then is the default about:blank tab. But the weird thing is, that this tab has not the focus. Same happens if I open another tab in background, before closing the homepage, and then close the homepage tab. Then the new tab is displayed (the content) but has not got the focus (visible in the tab bar). Also in both cases the address bar does not reflect the now correct address, it still shows the address of the closed tab. This behaviour only happens in FF3/Minefield. Reproducible: Sometimes Steps to Reproduce: 1.Open Browser 2.Close Homepage -OR- 1.Open Browser 2.Open Page in Background Tab 3.Close Homepage Actual Results: The tab, that should be active has not the focus in the tab bar. Also the address in the address bar is not correct, but the old address of the closed tab. The content display is correct (page, which was loaded is shown in the content area) Expected Results: Tab bar should activate the a) empty tab or b) the background tab, that now came to be the foreground tab. And the address bar should display the correct address of the now active tab. Using: Minefield 3.0b2 pre 2007111505 Default theme.

Created attachment 288982 [details] Screenshot of the given error Did some research and found this additional hints: 1. My homepage is (as can be seen) a https-site 2. the homepage is a redirection from another address (not https) This bug always occurs if you open that page and close it. With other homepages I could not reproduce the bug.
Correction: Redirection comes from another https-site. Hope those information helps to find the reason of the bug. If you got any questions, feel free to ask me.
We need to get this confirmed before we can accept it as a blocker nom: Johnath, can you dedicate a couple of cycles to looking at this? Jack: can you reproduce in safe-mode?
Mike: Yes I can reproduce that in safe-mode. Johnathan: I've turned on that option and it gives me loads of CSS errors (related to site obviously) and one "content is null" chrome://browser/content/browser.js and an information saying "SessionStore: TypeError: aWindow.getBrowser().currentURI is undefined"
there's not such a line (anymore?) in browser.js and i cannot reproduce with given STRs. so this is likely WFM with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b4pre) Gecko/2008030206 Firefox/22.214.171.124 ID:2008030206 ...
Version: unspecified → Trunk
I still can reproduce this error with nightly build 2008030305. But there is a new error in the console: "content is null" still is there and a new: "this.mCurrentBrowser is null" -> chrome://browser/content/tabbrowser.xml
It's been over two years, can this still be reproduced? I can't get the behavior on 3.6 or 4Beta8. If you can still reproduce it, what extensions are you using and what tab-related preferences have you tweaked?
Resolving WORKSFORME, please reopen if this is still an issue.

I cannot confirm, if this still happens since i do not have access to the same setup as back then anymore and more importantly cannot access that particular site that caused the problems anymore.
