Closed Bug 617795 Opened 10 years ago Closed 10 years ago
Blank tab is not closed correctly when it is about:empty or is the only tab
Steps to reproduce (thanks to a mibbit user on IRC): 1. Open a new tab. 2. Type "about:" in the urlbar and press enter. 3. Open the tab sidebar. Expected results: No undo close tab button. Actual results: Undo close tab button appears with a blank tab. This happens because we initially create a remote tab showing about:blank, then destroy it to create a local tab for the about: page. The patch fixes this by never showing "undo close tab" for about:blank. (It's just not that useful.) It also fixes a similar bug where extra tabs are created when opening pages with the about:empty start page showing, and another related bug where the blank tab fails to close if there are no other tabs.
I think this is a dupe of bug 615271
(In reply to comment #1) > I think this is a dupe of bug 615271 D'oh! Yes, it is. That fix looks good. This new patch will apply on top of bug 615271, and only fixes the related bugs mentioned in comment 0. I'll add a test later today too.
Depends on: 615271
Summary: Mystery "undo close tab" appears when opening an about: page in a new tab → Blank tab is not closed correctly when it is about:empty or is the only tab
