I can verify that disabling JS on firefox solves the problem.
I'm working with FF 3.0.5 on Red Hat 5 EL, Intel(R) Core(TM)2 CPU
6400 @ 2.13GHz, 3GB Ram.
My CPU usage without FF is ~6%, with FF 90%.
To test this -
1. Using firefox 3, JS enabled. Open http://ynet.co.il in 10 new tabs
2. Measure CPU usage in 5min interval. You should see a constant
increase in CPU usage until the point where FF hangs and needs forced
kill.
Now repeat the test, with JS disabled (Edit>Preferences>Content,
uncheck "Enable JavaScript").
To work around this bug,
First install Greasemonkey
https://addons.mozilla.org/en-US/firefox/addon/748, then install this
script http://userscripts.org/scripts/show/32443
Now install http://noscript.net/getit
To verify the workaround, browse to ynet, You should see in the upper
right corner - where the news flash used to be - the NoScript logo.
Note that this also disables your ability to read / post comments, If
this functionality is required the easiest solution IMHO is to click
on the "S" icon on the right and selecting "Temporarily allow all this
page"
HTH
P.S - If someone has a better solution on how to block just the
required JS code on ynet.co.il (Using AdBlock Plus) or something
alike, I would love to hear it.
