Mozilla using 100% CPU?

[Zoist]

Just recently been keeping an eye on my Gkrellm util, and find that when using Mozilla, it uses 95-100% of CPU usage all the time when the browser is open.
Is this normal? Or can anyone suggest a better browser?

I've seen this happen at times also, but not all the time. Usually about 20% or so when loading a new page.

Is it constantly at 100% for you? or is it after you hit a certain page it jumps us? When I hit 100% for mozilla it is usually from a page that has some insaine flash banners (gamespy network is good at this) or there was some java code that went bonkers (if your going to use java...learn how to use it correctly ;))

When it's topped out like that open a console and take a look at top, sometimes it gives you an idea if it's a plugin or mozilla itself...also, what are your system specs? I haven't looked at the stats when I run mozilla on my laptop (p150) but I know it jams the CPU pretty good...

It's strange even when the browsers are just sitting idle the CPU is maxed out :confused:

System:

256mb ram PC-133
Asus A7V
AMD XP 1800+ @ 1.16Ghz
Red Hat 8.0 with updates from Red Hat
Logged in as root. Always anyway.

Isn't that suppose to be 1.53GHz? or are you underclocking ;)

I use RH8 also and I don't have this problem...try making a user, login as that and try mozilla from there. It almost sounds like there is something in mozilla itself that is running mad...If you don't want to be bothered with user accounts, you can try deleting the .mozilla file in your home directory and see if that helps (you might want to save your bookmarks off first ;))

Thanks for the tips. Why is surfing as root a bad thing? I find it more easier using root because I don't have to bother su all the time. I am always fiddling with system stuff.
I should also note that I'm behind a firewall on a network if that makes any difference.

True about the 1800+ to run at 1.53, but because I am using an older Asus board, it only supports XP CPUs up to 1.16Ghz and up to 1.3Ghz Durons I think.
I had a Athlon 800 CPU die and I thought I would get a XP CPU, but haven't done the mobo update yet.

Because if you do happen to stumble across something malicious, any damage will be held at the user level rather than at the super-user level.

One could, for example, embed a

rm -rf /*

in a malicious open office maco. Open and run as root, well, you see the problem; but open an run as a regular user keeps the damage contained to one's home directory. Bad enough, but no a disaster.

Indeed, it is good practice to not run X as root.

Mine jumped to around 30% when loading a page and back down to 0% while in Mozilla as root.

Thanks for the replies guys.

Update:

It must have been a Web page which might have had some baddy plugin or some crap which hogged my CPU. :eek:

Cheers.
