Not a dup. Bug 583476 is about the HUD Web Console, this one is about the Chrome Error Console.

WFM, did you try to use the key command or the menu item?

Comment 4

[Erik Vold]

This is working now for some reason, when it wasn't working it was just for one profile, and I tried a couple of others and those worked, eventually rebooted and now it's working. Anyhow I can't reproduce this now so I'll close.

I tried the menu item

Have you eventually used Panorama during that session?

I had a problem with the Error Console in one of my testing profiles. Console would not open via menu or keyboard shortcut. Creating a new profile fixed the issue. Seems like there might be something here.

[Rob Campbell [:rc] (:robcee)]

also, I noticed this inability to open the Error Console before the patch landed in bug 593538.

Reopening as unconfirmed. I'd like a test-case that shows how this happens.

no

I had this problem for a time, I also saw the download manager wouldn't open for a while too. Both of them resolved themselves after a while though.

from a discussion in IRC, I was pointed to localstore.rdf in my profile.

  <RDF:Description RDF:about="chrome://global/content/console.xul#JSConsoleWindow"
                   sizemode="normal"
                   screenX="-1449"
                   screenY="563"
                   width="3383"
                   height="332" />

sure enough, these values are out-of-bounds and suggested what I did to cause it:

1. Open the Error Console.
2. Move the Error Console to the left of the screen and make it wider using the resizer.
3. Repeat step 2 moving it left of the screen boundary.
4. Quit Firefox when the console is sufficiently large
5. Restart, open the Error Console

Expected Result:
Error Console should open. What happens, Error Console does not appear.

Let me know if this matches what you're seeing and if possible, relay the contents of the JSConsole's section of localstore.rdf.

I was using a 2nd monitor before this happened, and likely had the error console on the other screen, it wasn't plugged in when I experienced this issue though.

I blame hardware:)

I blame our window opening code. Moving to something more widgety.

I've seen this too, and Cww found some other very-likely dupes. It seems that this regressed around the early betas. I got some more info today:

On 3.6 if a window was entirely offscreen it is moved to ensure at least some part of it is visible. On 4.0 this is not happening and, worse, it doesn't have to be entirely offscreen, just to have a negative screenX.

Slightly simpler STR:
 - Ensure that your browser window is not "maximized" (resizing it a bit smaller should suffice)
 - Move window a few pixels offscreen to the left
 - Close window
 - Cmd + N to open window

Results:
  The window does not appear, except on the "Window" menu. Selecting it on the menu has no effect (for example, the options "Close Tab" and "Close Window" does not appear on the "File" menu)

To get out of this situation, open a few more windows using Cmd+N until one of them appears onscreen, or change the negative screenX value on localstore.rdf

Sounds good, Felipe. Pretty sure this should block final release as it's very confusing if you manage to do this accidentally.

[:Felipe Gomes (needinfo for replies!)]

Dup'ing forward as bz bisected the regression range on the other bug
