235111 - Mozilla hangs when Tab is pressed

Status: RESOLVED DUPLICATE of bug 232368

(Core :: JavaScript Engine, defect)

Description

[Claudius Ohrt]

User-Agent:       
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113

Mozilla hangs with 100% CPU usage if you press Tab on your keyboard directly
after opening a certain page. You can find this page attached or if you visit
http://webmail.t-online.de and select the link "Zugang über T-DSL/ISDN". I tried
this on two different computers both running W2K and Mozilla 1.6.
Since disabling JavaScript solves the problem I suspect it has something to do
with the JavaScript engine.

Reproducible: Always
Steps to Reproduce:
1. Open http://webmail.t-online.de
2. Click on "Zugang über T-DSL/ISDN"
3. Press tab button on keyboard

Actual Results:  
Mozilla hangs with 100% CPU usage.

Expected Results:  
The first link/control on the page should have been selected.

No errors occurs if JavaScript is disabled.
