Status: RESOLVED DUPLICATE of bug 141710

(Firefox :: Shell Integration, defect)

Description

[zaven]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Mac OS 10.3. Holding down the trackpad button on my G4 PowerBook anywhere in
Firefox's UI (including scroll bars and buttons) spikes the CPU usage to 100%.
This eats a LOT of cycles when the user's main way to scroll is the
click-and-drag the vertical scrollbar.

This bug has existed since at least 1.0.

Reproducible: Always

Steps to Reproduce:
1. Open firefox.
2. Click and hold in a blank area of the page.
--> Notice CPU at 100%.
4. Release mouse button.
--> Notice CPU usage returns to normal.
5. Click and hold on a scrollbar.
--> Same problem.

Actual Results:  
CPU @ 100% for duration of mouse-button-down.


I will start charging mozilla.org for lost CPU cycles if this isn't fixed soon.
