740921 - When using multiple tab groups, the "all tabs" button only appears when using the first tab group.

Status: RESOLVED WONTFIX

(Firefox Graveyard :: Panorama, defect)

Description

[KLB]

When using multiple tab groups in Firefox beta (v12) the "all tabs" down arrow is only appearing when using the first tab group.  It is not being displayed in the tab bar when using other tab groups.

To reproduce:

1) open multiple tabs in the tab bar.
2) use the all tabs button to go to tab groups.
3) in tab groups move a tab or two to a new tab group.
4) open the new tab group.
5) look for the "all tabs" down arrow on the tab bar.

fwiw, I don't even get the 'all tabs' button in my first group - it only appears once I've exceeded the available width in the tab bar and scrolling is needed.

The error is coming from the "visibility: collapse" instruction in the following CSS at line 16 in chrome://browser/content/browser.css

=====
#tabbrowser-tabs:not([overflow="true"]) ~ #alltabs-button,
#tabbrowser-tabs:not([overflow="true"]) + #new-tab-button,
#tabbrowser-tabs[overflow="true"] > .tabbrowser-arrowscrollbox > .tabs-newtab-button,
#TabsToolbar[currentset]:not([currentset*="tabbrowser-tabs,new-tab-button"]) > #tabbrowser-tabs > .tabbrowser-arrowscrollbox > .tabs-newtab-button,
#TabsToolbar[customizing="true"] > #tabbrowser-tabs > .tabbrowser-arrowscrollbox > .tabs-newtab-button {
  visibility: collapse;
}

This is working as intended (bug 714281).

Okay, but as the panorama button is (by default) within the dropdown you can't access it.  I see the panorama button is added once you actually get into the interface the first time but its not added on upgrade from Fx11 to Fx12 (and also not restored with 'restore default set').  You want me to log a new bug for that?

The button shouldn't be added on upgrade. It should be added when you start using panorama, no matter if that's in Firefox 11 or 12. In case you removed it manually, you can just add it back manually.
