I have adblock enabled, with the following relevant filters: http://www.ynet.co.il/NRFrame/AdJumper/* http://www.ynet.co.il/Ext/Comp/Teaser* http://pbid.pro-market.net/engine?* I have the Flash 7 Plugin, although I don't see any flash animations, since they are blocked by Adblock. Reproducible: Always Steps to Reproduce: 1. Open FireFox 0.10PR (1.0 Preview Release) 2. Browse to URL: http://www.ynet.co.il Actual Results: Page loaded as expected. Looks great. CPU Usage Increased gradualy while page was loading, reaching its peek (around 40%), when page loading finished. Stayed that way all the while i was in the site. (I didn't browse to any pages inside the site.. just staying on the main page yielded this result) Expected Results: close to 0% cpu usage, Like most other web-sites produce. (Including this bug-report page)
I experienced the same scenario at that site (http://www.ynet.co.il), with Firefox 0.1PR on Mandrake 10.1. This is how 'top' looks like AFTER the page loads fully: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 6027 dovix 16 0 100m 45m 39m S 76.5 12.0 6:46.80 mozilla-firefox And it stays that way till I close the tab. This happens with or without Adblock. I disabled Java Script and then the CPU usage goes down. Konqueror does not experience the same behavior, so I would guess this is a JavaScript related bug in Firefox or Gecko.
Summary: CPU Usage Averages at about 40%. I have Adblock Enabled, and blocking all Advertising images or Flash movies, → CPU Usage Averages at about 40%. I have Adblock Enabled, and blocking all Advertising images or Flash movies,

Seeing ~40-45% with seamonkey and Flash enabled. Seeing ~5% with MSIE. But I wonder if this isn't a dupe of something... someone please try to construct a simpler testcase.

i suspect this has to do with the news scroller. the scroller appears in the front page and in the news section (http://www.ynet.co.il/home/0,7340,L-2,00.html), and in both places i get 40%-60% CPU usage. in other sections the CPU usage drops to less than 10%. with a tab open with the news section, when the window with that tab active is in itself active, CPU usage is around 40%-50%. with the front page in the active tab, it's 50%-63%. when the window is not active, usage is 27%-38%. in other sections, the usage is less than 10% most of the time. using WinXP on P4 2.66GHz, 480MB RAM.

The problematic section is indeed the scrolling "news-ticker". I've isolated only this part of the code, and removed most of the unnesecary info. When this html file is opened in mozilla, CPU usage jumps up to 40%. When opened in MSIE it stays 0-2%.

the summary is really crappy here. how about "CPU usage raises to 40% when viewing ynet.co.il"?

The same thing happens in http://www.nrg.co.il Apparently this happens in any site that has a scroller in it (however, I can't think of any other site with a scroller).

(In reply to comment #9) > Created an attachment (id=163478) > The HTML file that is consuming 100% CPU > This is a new example, from http://www.developers.org.il This one drives my CPU load to 100%, making the system terribly slow. Again, a problem with a news ticker. The HTML page that seems to include the problematic code was attached in my previous message.
