dropdown boxes on sites stop working

Thank you for reporting this to Ubuntu. How much RAM do you have and how many tabs are open in Firefox (approximately)?

Also, if you clear the error console (Tools -> Error Console) and try a drop down, do you get an error?

Could somebody with this issue please install the build of Firefox in my PPA (https://launchpad.net/~chrisccoulson/+archive/ppa/+packages), then run Firefox from the console with "NSPR_LOG_MODULES=Widget:3 firefox", recreate the issue and tell me if anything appears on the console each time the popup fails to appear

Chris,

   Presumably I need to add your PPA to a repository list somewhere to be
able to do this?

You can do:

sudo add-apt-repository ppa:chrisccoulson/ppa

... and then upgrade as normal

Anyone?

Despite trying for an entire day in multiple desktop environments, I haven't managed to trigger this even a single time so I'm dependent on one of the reporters providing the information I ask for here. Without that, the chance of us getting to the bottom of this is basically zero.

Also, what desktop environments are people using?

Hello, thanks ofr the link.

After the upgrade Firefox is working normally.

Im using Gnome 3.4.1
Kernel 3.2.0-24-generic

My laptop its a HP Pavilion g7
Amd PhenomII quado core, 8gb of ram

And im using and external screen.

Regards,
Marco Carranza

I can reproduce this as told in bug 1011163. Right click still works in "View source" window but immediately after closing the said window, right click stops working in FX.

Then I installed the debug version of FX from your PPA. The bug wasn't reproducible (by "View source" method) in the first tab I opened but after opening a second tab and trying again, the bug occured. Here's the output:

-1194391744[7f4db7914480]: GrabPointer: pointer grab failed: 2 (time=0x4fd76533 retry=1)

Setup:
up-to-date 64-bit Precise
Unity 2D
Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:13.0) Gecko/20120611 Firefox/13.0
5 tabs
2GB of RAM
Default Ubuntu FX extensions and Finnish localization

Excellent, that confirms my initial suspicion. Thanks!

Did you get 1 line of output for each attempt to open a popup? all of the pointer grabs are attempted with the same timestamp, which is definitely quite broken

@10 Yes, one per an attempt. I also found a way which triggers this. If I use keyboard shortcuts to open and close the "View source" window (Ctrl+U, Ctrl+W), the bug doesn't get triggered. The bug triggers when I close the "View source" window from window's Close button.

Thanks.

Out of interest, how long has your system been running? The timestamp there is equivalent to around 15.5 days.

@12 19:49:51 up 1 day, 11:43, 2 users, load average: 0.96, 1.02, 0.93

Also, could you please try something in gdb for me too? You'll need to install the debug symbols (firefox-dbg), which are quite large.

If you could do the following, it would be a great help:

$ NSPR_LOG_MODULES=Widget:3 firefox -g
(gdb) run

Once it has started, interrupt it with CTRL+C, and do:

(gdb) break GrabPointerError
(gdb) cont

When the problem occurs again, it will stop (and there should be a message on the console again). Could you then please try:

(gdb) p/x sLastUserInputTime

What value is it? And is it the same as the timestamp in the error message?

Also, when the problem occurs, would you mind also running "xprop", clicking on the window and pasting the output here?

Thanks

@14 No, it's not.

And finally a log file, generated using xtrace.

I could reproduce this by opening a new window, then closing it using window close button. However when I close the window using shortcuts (Ctrl + W), the bug doesn't occur.

Thanks to Jiri for sticking around on IRC last night to help debug this. What we found in the end is that the unity 2d panel sends Firefox a WM_DELETE_WINDOW client message with an abnormally large timestamp when closing a maximised Firefox window, using the close button. What happens inside Firefox (well, inside gdk really) is that it saves the timestamp of each new event on its GdkDisplay as long as the timestamp is newer than the previous one. Firefox uses this last event timestamp for pointer grab handling and drag events. Once Firefox has seen the timestamp from a long way in the future, this broken timestamp is then used for all future pointer grabs (which fail because the timestamp is ahead of the X server time).

After looking at the unity 2d source, it actually sends the system time (ie, time since the epoch) as the timestamp, rather than the X server timestamp of the mouse button event.

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

Note that there is an update unity-2d package in my PPA which has a fix for this (https://launchpad.net/~chrisccoulson/+archive/ppa)

Could somebody tell me a little about the release process and timing? When will this fix get released?

I'm very affected by this and other unity-2d bugs. I see that this has been marked for 5.14, and other fixes I'm waiting on marked for 5.12.1. When will these get to Precise? I'm getting scared that it means "no time soon."

My desktop is Kubuntu and I have this problem very often, it will almost always happen within 5 minutes, after I started Firefox, sometimes I start Firefox, open 2 tabs, then dropdown box and context menu dissapears immediately.

Since I don't have unity-2d at all, this fix may not be the cure for me?

KDE plasma widget: window menubar also need to communicate with Firefox, so it may be the widget need to fix? or the problem is actually from Firefox?

Just in the last few days I have seen dropdown boxes fail to work, though I have not worked out what is triggering it. I have unity-2d 5.12.0-0ubuntu1.1 on Precise up to date. Is it possible that the fix here has triggered a new problem?

I can replicate it by using the HUD to find a Firefox bookmark. Should I report a new bug? Or perhaps it is already reported.

It's probably best to report a new bug. Open one up and post the link here for those still affected to hop on. I, too, have this issue on Unity3D.

I have reported the new problem in bug #1034419.
Chauncellor - if you see the issue with 3d could you comment there as I can only replicate it on 2d.

so it is solved? I am using ubuntu 11.10 with unity-2d 4.14 but still confront this problem. Any work around for me?

Ubuntu11.10 is end of live. There will be no further upgrades to this system.
