(Firefox :: General, defect)

Description

[Mike]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Load http://www.weather.com/weather/local/60004 then Click 10-Day forecast. When
page loads Click Back. Firefox crashes. Performing the same procedure in Mozilla
1.7.8 produces the same crash.

There seem to be a number of recent talkback results showing this problem. I
believe talkback id 5786783 is one of mine. Search talkback on url:
www.weather.com for the past few days and about 200 similar crashes appear.

Reproducible: Always

Steps to Reproduce:
1. Open http://www.weather.com/weather/local/60004
2. Click the 10-Day forecast button.
3. Once the 10 Day forecst page loads click Back.

Actual Results:  
Firefox crashes (XP reports a crash; Talkback opens)

Expected Results:  
Loaded the previous page.

Talkback implicates js_FoldConstants

Reporter, can you please try in firefox's safemode and/or with a new profile,
and report back as to whether the crash still occurs? Thanks!

-safe-mode: No Change (crashes).
New profile: Crash does not occur in mozilla 1.7.8 or firefox 1.0.4.

Tinkering with various settings in both the UI and about:config let me solve the
problem with the current (old) profile in mozilla. In firefox, I had it resolved
for only one or two tries; then it crashed again. I think the issue is related
to turning on single window mode (
user_pref("browser.tabs.showSingleWindowModePrefs", true); )but I can't find any
pattern now.

That seems likely. With both the new profile and a "cleaned up" original
profile, I can reproduce the crash on weather.com on some visits to the page,
with a restart of the browser in between. So my thought that it was related to
single window mode seems incorrect.

Talkback now has about 189 js_FoldConstants crashes at www.weather.com in the
last 3 days on both windows and Mac OS X.
