Drop downs, drag-and-drop and right click menus don't work with Mozilla ff/tb 14.0

Subscribing Desktop and Security teams, as this is a blocker for the Natty release of Firefox and Thunderbird 14.

Thanks Tyler, do you use the most recent update of unity-2d there? Do you confirm it's a regression on the same environment from tb13? Do you get the issue every time?

Yes, unity 3.8.4.1-0ubuntu1.2 was installed.

It is regression on the same environment from tb13. Within the same session, I downgraded to thunderbird 13.0.1+build1-0ubuntu0.11.04.1 and verified that drop downs do properly work with that version.

The issue is reproducible every time.

Ok, thanks, I guess it will need investigation then, natty is current low on our priority list though, especially for unity-2d issue knowing that it was the very first version of unity-2d and likely an environment still using by very few users on natty still

I experience the same on Ubuntu 12.04 64 bits but only with firefox. Every symptom for firefox is confirmed for me.
Thunderbird 14 works OK.

For firefox, everything was fine, until the upgrade to 14.

After a system restart, the problem is gone...

As I mentioned in Bug #1026747 I am having this problem in KDE. It went away when I downgraded to Firefox 13.0.1.

Since this happens outside of Unity and has not gotten any attention, I'm marking it as affecting Firefox (Ubuntu).

Status changed to 'Confirmed' because the bug affects multiple users.

This has been reported elsewhere as well:

https://bugzil.la/779900
https://support.mozilla.org/en-US/questions/932643

This is a serious problem that makes Firefox unusable. Being stuck on old versions is not acceptable.

If this bug is specific to Unity, it might not be the same bug as https://bugzil.la/779900 and https://support.mozilla.org/en-US/questions/932643, which is confirmed to affect a Kubuntu user (me) and a Xubuntu user. Also, my brother (who uses Unity) has a bug that's just like this, only his menus come back when he right-clicks his tabs. See if that works on this one.

I doubt this is Unity-specific. It's probably Gtk-related, perhaps connected to the way non-GNOME environments use Gtk. Just a guess.

Out of desperation, I followed a lucky hunch and disabled the extension "Ubuntu Firefox Modifications 2.1.1". That seems to have fixed the no-menus problem on multiple systems. So it seems to be a bug in the xul-ext-ubufox package--apparently it's incompatible with Firefox >= 14.

Um...I take that back. Literally, as soon as I pressed Post Comment for the comment above, menus stopped working in Firefox. It's almost like Firefox is playing some kind of sick joke on me.

When I right-click anywhere in the browser, on a page or in the chrome, the menu begins to draw, but disappears before it can even fully appear. It barely flickers into view, and sometimes it doesn't even do that.

And it's happening in Firefox 15 now.

it's happening in Firefox 15. I use Xubuntu 12.04.

I think I have tracked the bug down to the "Global Menu Bar integration" extension, aka firefox-globalmenu. When I disable this, the menus work correctly.

Again, I never had this problem before Firefox 14.

firefox-globalmenu:

Disabling that extension works on my end as well.

Thank you for reporting this bug to Ubuntu. natty has reached EOL
(End of Life) and is no longer supported. As a result, this bug
against natty is being marked "Won't Fix". Please see
https://wiki.ubuntu.com/Releases for currently supported Ubuntu
releases.

Please feel free to report any other bugs you may find.

This bug is not version-specific. Have you noticed all of us mentioning that we have it in other versions of Ubuntu? I'm running 12.04 and I still get the bug unless I disable the Unity extension.

This bug occurs frequently on Kubuntu as well (I'm currently on 12.10).

I sent him a message to reopen the bug.

I just had this hit me with kubuntu 12.10 and firefox aurora, I updated to the latest (20.0~a2~hg20130131r123843-0ubuntu1~umd1~quantal at the moment) and it made no difference.

I can left click on links and tabs, but I cannot open menu items and cannot right-click on anything

as far as extensions, adblock, flashblock, flash, java (I can't get a full list without being able to access the menus)

I think this bug has several related or duplicate bugs:
bug #617800, bug #757523, bug #780065, bug #781815, bug #912673, bug #1017604, bug #1017828, bug #1027784, bug #1020198

These bugs certainly all have the same symptoms, and now we know another possible cause it switching workspaces. As for the Windows users among those links, I remember having the same problem back when I used Windows (many many years ago) that I fixed by disabling the Menu Editor extension.

If duplicate markings are performed, it definitely needs to be done in a way that keeps the vast amount of information that we've collected in this report front and center.

it also appears with KDE’s plasma-widget-menubar: as soon as the menu it operated the first time after restarting firefox, all popups break in the described way (only flickering into view once instead of staying open).

makes using bookmarks almost impossible as you have to go over the menu, and, since middle click in the dbus menu doesn’t work, you also have to open a new tab beforehand if you want the bookmark in a new tab. pretty annoying :/

^I can vouch for this. When I experienced the bug, I was using the KDE menubar widget. I stopped using it when I had to disable Firefox's ability to interface with it so that the bug would stop.

You can still use the Plasma widget for other apps if you remove
firefox-globalmenu.

I know, but it was insanely awkward to have all my programs EXCEPT Firefox use it.
