Status: RESOLVED DUPLICATE of bug 141710

(Firefox :: Tabbed Browser, defect)

Description

[Mike Feeney]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

I'm using a dual 2.5Ghz G5 PowerMac, and a Wacom Graphire 2 graphics tablet /
mouse.  In Firefox, if I left-click and hold anywhere in the browser window, the
CPU usage for the program hikes from about 5% to 98.8%.  The fans also cycle up.
 When I release the left-click, the CPU and fans return to normal.  

Reproducible: Always

Steps to Reproduce:
1.  Launch Firefox
2.  Left-click and hold anywhere on the page.  CPU usage will skyrocket.
3.  Release left-click.  CPU usage returns to normal.

Actual Results:  
The CPU usage (as reported by Activity Monitor) increased from 5% to 98.8%, and
returned to 5% when I released the mouse button.

Expected Results:  
I expected the CPU usage to remain constant or change very little.

I am using the default view.  My mouse is a Wacom Graphire 2 graphics tablet and
mouse.  I am running OS X version 10.4 (Tiger).

1) Did you upgrade tiger ?
2) Upgrade firefox, your version is too old and it is very dangerous to use it !

No problem with my Mac mini 1.42 Ghz / 512 mb / Tiger 10.4.1 and a 2 hours old
homemade trunk build.

Yes, Tiger was an upgrade install.  I'll update Firefox.

Updating to Firefox v. 1.0.4 had no effect - The same thing happens when I
click/hold and release the mouse button.
