511570 - Blank modal sheet appears sporadically, prevents operation

Status: RESOLVED DUPLICATE of bug 476541

(Firefox :: General, defect)

Description

[Joe Sewell]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2

At various times, for reasons I cannot quite explain, Firefox will display a blank modal sheet. From the most recent occurrence it appears to be the warning for a script that is running too long ... but with the sheet blank, I cannot tell, of course. Clicking within the sheet produces no reaction. The menu bar is reduced to the Apple menu and the Firefox menu, both of which can be dropped down, but the latter is non-functional (e.g., using Quit doesn't do diddly). I have to Force Quit Firefox.

I happen to have a session saved using the Session Manager extension that seems to cause this to happen consistently; one particular tab comes forward and the blank sheet pops up. I will attach a zipped copy of these files. I'll refrain from uploading my list of extensions unless they are needed.

Reproducible: Always

Steps to Reproduce:
1. Install the Session Manager extension
2. Launch Firefox
3. Select any of the sessions attached to restore.
Actual Results:  
FarmVille tab pops forward, blank sheet drops down.

Expected Results:  
Sheet should at least be dismissible.

Joe, do you see this with current v3.6 or trunk build?

Comment 3

[Joe Sewell]

Yes; it still happens occasionally with 3.6.3 (Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 - Build ID: 20100401064631). Still have not been able to find a reliable set of steps to reproduce, other than the sessions I uploaded. Have not tried any 3.6 betas, and 3.7 will not run on my older machine.

Joe, does bug 476541 read like same issue? 
If you don't see the second window, it might be hidden. eg bug 543421

Comment 5

[Joe Sewell]

I suspect bug 476541 is related, perhaps even the same root problem. In this case, though, I know it's *not* due to a second window. In the cases I found, I watched closely, and saw no second window pop up, nor did I expect one.

Reporter, are you still seeing this issue with Firefox 4.0.1 or later in safe mode or a fresh profile? If not, please close. These links can help you in your testing.

Cannot use Firefox 4.x on my machine.

No reply, INCOMPLETE. Please retest with Firefox 4 or later and a new profile (http://support.mozilla.com/kb/Managing+profiles). Also, ensure you have the most up to date graphics drivers, operating system updates, and plugin versions (flash, java, etc). If you continue to see this issue with the newest Firefox and a new profile, then please comment on this bug.

Tell me, "Triage" (since you don't have the courtesy to look up my name, let alone see THE REPLY I LEFT THAT YOU COMPLETELY IGNORED!!!), are you always this big of a jerk?

This issue is N-O-T resolved in any way, shape, or form! If you're willing to buy me a newer machine on which I can try Firefox 4, that's fine. Otherwise, this "Reporter" will consider the Mozilla project to be 100% unsupported.

Then please test with Firefox 3.6 in a fresh profile and report back. Also, read https://bugzilla.mozilla.org/page.cgi?id=etiquette.html while you are at it. This bug still had the CLOSEME tag, meaning it was on the list of bugs to get closed after date X. There are many thousands of bugs, and only a few volunteers like myself to go through them. I'm sorry yours fell through the cracks.

I have little doubt this is would be fixed by bug 476541, and that this bug isn't going to go anywhere without action happening in bug 476541.  So duping there.  (FWIW, iirc 476541 has also been known to happen without a second modal dialog being visible)

After it's fixed on trunk, bug 476541 is also where you would request the patch be ported back to FF 3.6 - ut at bug 476541's current rate of progress, I highly doubt a fix will happen before v3.6 is EOL, in which case the question of getting a fix for Mac 10.4 users will be moot.
