Is this a regression from the checkin of bug 571782?
(In reply to comment #1) > Is this a regression from the checkin of bug 571782? No, in a sense this is new (not a regression in a working feature per se) since before bug 571782 landed "New Tab" wasn't available in the Firefox button. Also, a tabbar/menu bar has never (or hasn't in forever) been shown in a popup window so this case has just never been brought to light. I couldn't get keyboard shortcut CTRL+T to work so I'm assuming this case might have been taken care of before so maybe bug 571782 just didn't account for this.
Sorry, meant to CC Dao on my last comment. Dao, what do you think should happen here?
In Firefox 3.6.8 the given webpage is showing a menu bar in the popup, and it is also possible to open new tabs in it, the tabbar will be displayed then. So I think it is a rather new behaviour to disallow opening new tabs in popups.
Doesn't block, but I'd love to see a patch that made things consistent, here.
(In reply to comment #5) > Doesn't block, but I'd love to see a patch that made things consistent, here. In the current build, both menu items are enabled in popups now. (I do not know what caused this.) So it is consistent, though it does not make much sense this way, as it is not possible to open new tabs in popups.
(In reply to comment #6) > In the current build, both menu items are enabled in popups now. I was wrong, sorry, this is only the case when browser.tabs.closeWindowWithLastTab = false (see bug 577382). Though, in that case, it is not actually possible to open tabs (see description).
I have tested this again using the current latest-trunk version, and some things have changed. This bug is now independent from browser.tabs.closeWindowWithLastTab pref. To test this, the popup must have the attributes menubar=1 and toolbar=0. In that popup, the minefield button will be displayed. Clicking it will show the root menu with the item "New Tab" greyed out. The belonging submenu will not be shown on hover. Clicking the greyed out "New Tab" item does still open a new tab in the popup though! These errors occur: Error: newBrowser is undefined Source File: chrome://browser/content/tabbrowser.xml Line: 867 Error: content is null Source File: chrome://browser/content/browser.js Line: 5515 Trying to close the tab (seen as white content only) using CTRL+W shows this alert: ASSERT: Giving up waiting for the tab closing animation to finish (bug 608589) Stack Trace: 0:([object XULElement],[object XULElement],-5) and this error: Error: this.selectedTab is null Source File: chrome://browser/content/tabbrowser.xml Line: 1679 Then closing the popup: Error: aWindow.content is null Source File: resource://gre/components/nsSessionStore.js Line: 845
Created attachment 512267 [details] [diff] [review] patch fixes the remaining issue from comment 8
Comment on attachment 512267 [details] [diff] [review] patch Maybe worth a 1-liner comment? Also, we should disable the hover effect for the menu arrow part of the splitmenu when it's disabled... Followup?
(In reply to comment #12) > Also, we should disable the hover effect for the menu arrow part of the > splitmenu when it's disabled... Followup? It's actually the other way around, the hover effect is missing for the menuitem part. Filed bug 638431.
