(Firefox :: Menus, defect)

Description

[Fabricio Rocha]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071618 Firefox/2.0.0.2 (Debian-3.0.1-1)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071618 Firefox/2.0.0.2 (Debian-3.0.1-1)

It has happened several times already, while browsing in many different sites: when I try to open the context menu (mouse right-button) over a page, the menu itself does not appear but instead one of its items is randomly activated -- such as "page properties", or "save to...", etc. 

Reproducible: Sometimes

Steps to Reproduce:
1. Just go browsing through, and try to open the context menu with the mouse right-button.
Actual Results:  
A random item of the context menu is activated as if it was clicked.

Expected Results:  
The context menu should appear and allow the user to choose an option.

The machine is a AMD Sempron 3000+, Debian Linux (kernel 2.6.21) system with KDE 3.5.9. Some Firefox extensions are installed, as DownloadHelper, DownThemAll and Linky.

This works fine for me using Firefox 3.0.1 on Windows XP.
Did you also test this in safe-mode: http://kb.mozillazine.org/Safe_Mode_(Firefox)
