Description Ben S. Stahlhood II 2007-06-14 14:07:52 PDT

There seems to be an issue when loading pages that have QT movies.  Memory consumption goes from 30-50K range to over 230K range and stays in the 200K range, even after closing the movie and leaving the site where the movie was hosted.


Memory Test

At launch
=========
* All go to start page google.com

FireFox - 27,992K
IE      - 33,652K
Safari  - 38,476K


Load Page www.apple.com
=======================

FireFox - 28,920K
IE      - 38,560K
Safari  - 44,752K


Load Page www.apple.com/mac
===========================

FireFox - 34,328K
IE      - 52,324K
Safari  - 56,872K


Load Page www.apple.com/macosx/leopard/
=======================================

FireFox - 40,368K
IE      - 52,284K
Safari  - 62,852K


*Click "Watch the Demo" under Desktop

FireFox	- 78,288K
IE	- 107.144K
Safari	- 244,932K


Load Page www.google.com
=======================================
*memory stayed pretty constant for each browser, even
after I left them sit for awhile.

FireFox	- 53,624K
IE	- 59,512K
Safari	- 218,032K


Minimizing Browser
================================
* This last step was interesting.  After I completed all the above
steps, I minimized each browser and got the following results.

FireFox	- 67,032K
IE	- 1,500K
Safari	- 3,452K

Thanks for the detailed bug report!  Just to confirm:  your "Minimizing Browser" step is simply clicking the "minimize" button in the title bar while still looking at the Google web page?
