Slickdeals reply form causes laptop to heat up (Firefox 4 Beta)

No joke. Preface: I'm using the latest version of Firefox 4 beta.

I noticed that as soon as I opened up a reply or post page on Slickdeals, my laptop started to get quite warm. I opened up task manager and discovered that as long as the reply box is in view, Firefox consumes between 20 and 50% CPU usage. This results in my CPU heating up to 80 C.

Note: I've already ruled out my computer configuration. There's nothing wrong with any of my computers and this happens on all of them.

I'm not sure if this happens with the current regular version of Firefox. I'm also not really sure if this is Slickdeals' problem (Javascript maybe?), but I thought I'd make someone aware of it. It may be a Firefox bug, in which case Slickdeals themselves filing a bug report with Mozilla would carry more weight than if I did.

We need more details on your laptop such like OS, processor, ram, hdd, ram, flash version, etc and which pages does it happen in and what pages it doesn't happen.

Any page with the full reply box. It does not happen on any other page, including those with the quick reply box. Interestingly as well, if I scroll the full reply box out of view, Firefox drops to 0% CPU usage.

OS is always Windows 7 with all patches applied. Running Security essentials on some, Symantec Antivirus on another.

RAM varies between 2 and 4 GBs of DDR2 800.

Processor is one of: Core 2 Duo T7700, Core 2 Quad Q9505 and Core i5 520M

HDD is either an HTS722010K9SA00 or a 7200 RPM laptop drive (don't have the manufacturer handy) or a 7200 RPM desktop hard drive (don't have the manufacturer handy)

Flash version is 10.1 r102

Graphics range from an nVidia Quadro FX 570M, Quadro NVS 3100M or an ATI Radeon 5770.

Doesn't matter if I have any Firefox extensions installed or not. This happens even with a fresh install of Firefox. But like I said, I don't know if this is new to Firefox 4 or not. But since 4 is still in beta, now is as good a time as any to report a bug, if it is a Firefox bug.

The specific machines involved are a Thinkpad T61p, Dell Latitude E6410 and I also noticed it on my self-built desktop (I just don't care as much since it's a quad-core and it's not sitting right on my lap. )

Just installed a stock copy of Firefox 4 Beta 7, loaded up

No performance changes in basic editing mode.
In WYSIWYG editing mode, i get a 10% cpu usage in one core sustained as reported.

No performance impact in any stable releases of Chrome, Firefox, Safari or IE. Since this is attributed to FF4, the best we can do is mark it as reproducible and we'll see about submitting a bug report. I dont think that we carry any extra weight than anyone else submitting a bug though

I figured out the exact cause. If I shrink the window so that the Smilies don't show up, the usage drops to 0-8%. As soon as I scroll the Smilies into view, bam, usage shoots up.

Thanks for looking into it!

Installed Nuke Anything Enhanced and wiped out the Smilies corral on the advanced reply box. All is cool now. NAE only seems to work on a page-by-page basis. All the reply pages look different to it. Back to the drawing board...

Or you can quit replying to posts (save your cpu juice, don't reply to this one!)

FireFox 4: Now with real fire!

Your CPU heats up to 176 degrees Fahrenheit???
