Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Ty Williams]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

If you load http://www.macdevcenter.com/, Firefox will load the CPU to 100%
until the window is closed.  If macdevcenter.com is opened as part of a set of
tabs (Bookmarks>Foo>Open In Tabs), the CPU usage will go to 100% and will
quickly crash Firefox.  Firefox must at this point be killed manually via Force
Quit or the Terminal

Reproducible: Always

Steps to Reproduce:
1. Launch Firefox
2. Load a bunch of bookmarks as tabs with macdevcenter amongst them
(Bookmarks>Foo>Open In Tabs, where Foo contains multiple bookmarks including
macdevcenter.com)
3. Firefox goes to 100% CPU load and eventually hangs completly
4. Manually kill Firefox
Actual Results:  
Firefox crashed, loosing all open tabs and the data entered in forms therein

Expected Results:  
Firefox should have remained stable

This involves TalBack crash numbers TB9961539Q and TB9716036E.

Both of those IDs are long past expired. Could you crash again and post some fresher ones?

Here's all my crashes for 1.5RC3  I think most of them are this issue.
TB12274022Y
TB12227702K
TB12222800E
TB12158657H
TB12115813K

Talkback hasn't been catching all the crashes either.  I would estimate I'm crashing 2-4 times every day.

you have new object creation, garbage collection and a couple of random crashes.

I want to dupe this as bug 314974.

I can't reproduce this on windows or mac os x 10.4.6 with recent builds. We have had a lot of fixing since this report. Marking works for me. Please reopen if you can reproduce with a recent 1.5.0.5, 2.0 or 1.9 build
