Did'nt you read AMDZone article which is pointed by jinexile on Feb Tue 7th 2006 in the thread of MozillaZine forum?
http://www.amdzone.com/modules.php?op=modload&name=News&file=article&sid=3951&mode=thread&order=0&thold=0 
This article seems to describe the problem correctly.
(points MSDN KB Q896256 http://support.microsoft.com/kb/Q896256)
See Bug 307527 Comment #101 also, and read three MSDN KB articles listed in it.

(Q1) Will /usepmtimer be a workaround? (MS Win XP SP2 is required)

(Q2) Can you apply Hot Fix(includes acpi-HAL update) for SP2 by MS?
If applying the Hot Fix is difficult, try latest driver update(includes acpi-HAL update) for Athron X2/MS Win XP SP2 by AMD. Will it resolve the problem?
(When try Hot Fix or driver update, disable workaround of "/usepmtimer".)

(In addition to comment #1)
(Q3) Will disabling of "Cool'N'Quiet" be a workaround?
     (When AMD. Sorry but I don't know equivalent feature name of Intel chip.)
     See the AMDZone's article and Bug 307527 Comment #6.

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
