491664 - reproduceable script error copying semi-large no. of bookmark folders within bookmarks library

Status: RESOLVED WORKSFORME

(Firefox :: Bookmarks & History, defect)

Description

[P. Geisler]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; de; rv:1.9.1b4) Gecko/20090423 Firefox/3.5b4 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; de; rv:1.9.1b4) Gecko/20090423 Firefox/3.5b4 (.NET CLR 3.5.30729)

When copying the "Lesezeichen-Menü" (Bookmarks Menu? I am using the German client) as a whole e.g. to the "Lesezeichen-Symbolleiste" (Bookmarks Bar) Firefox stops responding and after approx. 30 secondes pops up an warning message about an unresponsive script.

The full German text of the message:
"Ein Skript auf dieser Seite ist eventuell beschäftigt oder es antwortet nicht mehr. Sie können das Skript jetzt stoppen oder fortsetzen, um zu sehen, ob das Skript fertig wird.

Skript: file:///C:/Program%20Files/Mozilla%20Firefox%203.5%20Beta%204/components/nsPlacesDBFlush.js:192"

Stopping the script or keeping it running by selecting the corresponding button both have the same result, Firefox still is unresponsive for a couple of more seconds. In one case Firefox crashed completely, in all other attempts the bookmarks finally got copied.

My bookmarks menu contains 16 subfolders (plus the 3 original auto-folders for most visited bookmarks etc.), each folder containing between about 5 to max. 20 bookmarks.

Reproducible: Always

Steps to Reproduce:
1. Open the "Bibliothek" (bookmarks library).
2. Mark the "Lesezeichen-Menü" (Bookmarks Menu) and drag it to the "Lesezeichen-Symbolleiste" (Bookmarks Bar) folder.
Actual Results:  
Firefox unresponsive, followed by script error in file:///C:/Program%20Files/Mozilla%20Firefox%203.5%20Beta%204/components/nsPlacesDBFlush.js:192

Expected Results:  
Firefox should continue responding while copying the bookmarks in the background without scripting errors

I am running the following addons and themes:
4chan menu 0.4.5.12
Adblock Plus 1.0.2
BetterPrivacy 1.29
Cooliris 1.10
Download Statusbar 0.9.6.5
feedly 1.2b
Ghostery 1.3.9
NoScript 1.9.2.6
PDF Download 2.1.0.2
Stay-Open Menu 1.5

There is also an instance of Microsoft .NET Framework Assistant 1.0 listed as inactive because no longer supported by this version of Firefox.

On a sidenote, I expected the "Lesezeichen-Menü" copying to result in some kind of a symbolic link appearing in the "Lesezeichen-Symbolleiste" referencing back to the menu rather than actually copying all single bookmark entries. That's why I did this in the first place.

Confirmed on Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2a1pre) Gecko/20090504. This does not happen in Firefox 3.
When I put a check mark in the box "Don't ask me again" it completes the task normally AFAICS.

Correction: When I put a check mark in the box "Don't ask me again" and click on "Continue" it completes the task normally. I forgot some words.

P. Geisler, can you reproduce this with recent trunk build?  (there was recently a
places landing)

[Marco Bonardo [:mak]]

No answer, Firefox 4 should have made this largely faster, but we won't backport the fix (it's just too large and scary).
Please reopen only if you can reproduce in Firefox 4.
