326512 - Constant high CPU-load on this page

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Gregor Rosenauer]

I just tracked down a critical bug here that caused me quite some trouble over the past days:
When loading the page given in URL, CPU-load goes up to 70% here on my old Powerbook Titanium G4 500MHz with 512MB RAM and later stays between 40%-50%.
(I guess even on the newer Macs, this would still cause an unwanted CPU-load...)

The problem gets worse when you have other tabs open and is mostly noticable when editing inside a textfield (this widget seems to be quite a ressource-hog btw), e.g. wiki-pages.
I got a constant 70-80% CPU-load up to the point where text-input was *impossible* (but mouse still worked), even in file-dialogs text input was gone.

Using OS X 10.4.4 with all updates applied and Firefox 1.5.0.1 PPC.

Will check on WinXP.

I can't compare for the valentines script doesn't run at all in IE here.
When you block http://www.codedread.com/svgsnow-valentines.js with the adblock extension the cpu usage goes back to normal.
