CNET bashes Firefox.

The writer seems to imply that Firefox will burn up the CPU in your
laptop/netbook.
I can say that I run my netbook (Dell Mini 10) for several hours every
single day with Firefox, and one or two other applications active, and
there is no temperature difference noticed at any time, and I monitor
CPU usage constantly, and have NOT seen the symptoms mentioned in the
article. It might be because I don't allow much Flash to run, but is it
really fair to bash Firefox because Flash consumes CPU cycles?
I really HATE this type of misleading article.
Terry R.
Why is it misleading? If a moz support person "suggests" Safari is
possibly better at optimizing Flash-based sites compared to Firefox
(30-60% for FF, 2-10% for Safari), it would appear the issue IS with FF,
and not Flash.
I think the comments are pretty telling also. If anything, FF isn't the
golden calf you think it is...
I have an older laptop that has always had heat issues. The original
owner went through 2 hard drives that failed due to heat. They gave it
to me and I installed a 7,200 rpm drive (which runs hotter). I always
notice that whenever I open FF and do some work, the fan kicks on high.
Working on other apps doesn't have the same effect though. There may
be more to this than meets the eye.

indefinitely without overheating. I am more concerned with the implied
message than the specific facts, even though those definitely DON'T
match with my experience, first with an HP laptop, and now with a Dell
netbook. I suspect other factors may be at work here, especially since
my observations of CPU usage don't seem to match those in the article.
Terry R.
I don't believe a "properly designed" one can run 100% indefinitely. A
"specially designed" one to focus on heat, possibly.
You don't experience it, and it appears I do. The "implied message"
relates to my experience on a laptop (as the light went on after reading
it).

Guys, if this is just a continuation of your debate in mozilla.general,
then take it to mozilla.general.

users. I have no doubt that this happens, but many of us don't seem to
have the problem, even though we use the same hardware, and software,
and OS. Surely someone can discover just what causes this, so it can be
fixed. My bet is on an extension, or plugin.
Terry R.
Chris,
Far from it.
That was a cheap trick changing the newsgroup to general when it doesn't
warrant it.
Please don't change the newsgroup just because you think it belongs
there. This is specific to FF and should stay here, regardless of what
you think.

I guess I must be a "perfect designer" because every one of my homemade
computers from this antique Pentium 4 Shuttle SFF to my current newest
Q6600 HTPC run at 100% CPU usage 24 X 7 with no problems (four in all). The
machines are running the BOINC client with World Community Grid; despite
this I've never had a heat-related problem with any of them and that is
saying something since the P4 Shuttles had marginal cooling and the HTPC is
a super-low-profile Antec case with space for no sort of special cooling.
I don't abuse my notebook in this way but it has not shown any detectable
heat changes even running FF with 26 tabs open as is my normal habit. The
CPU usage figures on the note book do not come close to hitting those noted
in the article and I suspect that something totally different is going on.
I suspect that, based on the original article, that nobody is experiencing
thermal shutdowns which would be a sure symptom of a truly overheated computer.
Terry R.
No one said "perfect". I build all mine also, since that's what I do.
I have to doubt your machines are running 100% all the time.
So your notebook doesn't, and mine does. That would lend you not to
believe it and I have to give it some merit.
And do machines really have to experience a "thermal shutdown" in order
for Mozilla to take notice?
follow-up set to mozilla.general

I just tried FF 3.6b3 on my desktop machine, where I can monitor case,
and processor temps. I opened FF, went to the HarryPotter.com site,
which is almost completely Flash driven, opened 10 tabs, and let it run
the movie trailer in each one for 10 minutes. The case temp rose 2
degrees C, and the processors stayed at their normal temps, even though
both were about 50% busy. I think it is safe to say, whatever is
causing the problem with high CPU usage, and temperature increases,
isn't present on my system. BTW, I run about 25 add-ons.

Speaking stricly of Firefox - ON Topic - I have never had any
computer/notebook shut down because of overheating caused by excessive
CPU useage in Firefox, any version to date.
If the discussion escalates to general CPU useage, etc. please set a
followup to mozilla.general where we can discuss this at length and more
indepth. Thanks

I have seen that on gnome displaymanager on linux some sites are not as
responsive as they appear to be when I run fluxbox on a BSD machine,
both with firefox,
Sure on BSD I have no flash, which girds up thy loins.
When it crashes,, usually if I play piano with flash i get a coredump,
so far I have never been able to investigate what is going on in the
core dump. I just reload and it restarts and continues.
Sun has D-Trace, which works on solaris and IIRC on FreeBSD. It is a
tool which could troubleshoot this. You can still playback flash, even
on 64 bot OpenBSD, by separate downloading the file and playback outside
of the browser. IIRC mac has solved the flash problem by avoiding it,
hence on an iphone they have the agreement with youtube to stream mpeg.
a different codec and a different technology.
I don't know where I read this, but it may be that all youtube flash
videos are handled different on all mac iPhones and even PC's.
DTrace is here
http://www.sun.com/bigadmin/content/dtrace/index.jsp
It could help finding performence bottlenecks and instrument critical
sessions of unusual coded websites.
I can see no problem blocking flash and doing separate flash downloads
and ffmpeg to convert to mpeg. Flash is a security issue. Which is why
it is blocked on iPhone.
