ICEWEASEL 100% CPU

[mylittlepavilion]

Hello,

my Iceweasel hangs around with 100% CPU and laags so much. Please help me.

Thanks

You know, it helps to give information so people can actually help you?

What version of Debian are you using?
What version of Iceweasel are you using?
What addons are you using?
What are your desktop resources?
What addons are you using?

What are the basic specs of your computer?

I have also been seeing very high cpu usage for iceweasel, certain sites seem to trigger it. After a bit of browsing around, the symptom for me is that the cpu fan steps up. When this happens and I look at what is causing the load its always been iceweasel (stable version 31.7.0esr-1~deb8u1 I believe it is now, I'm not at the system now to check.).

When iceweasel runs amok the system does remain response but that may be because there is still a fair bit of head room. Running on a i7 4790 with 16 gig of ram here.

I found this article and may try this just to see if it resolves the issue. https://bernatarlandis.wordpress.com/20 ... when-idle/ I haven't had the time to try the solution so I'm not sure if its going to help.

I have a HP Pavilion 15-p150ng and Debian 8 with Iceweasel. The most lags are when facebook is opened.

I find this happening sometimes - suspect it is caused by malformed
javascripts. Usually solve the problem by closing the browser and
restarting. Adding the 'NoScript' add-on might help but some sites
don't work correctly with js disabled.

On occasion the problem persists even after closing the browser
(checked with 'top') in which case I do a 'kill -9'.

I have also been noticing Iceweasel pegging the CPU a bit for a while, not in general but on some particular websites e.g. amazon.com - generally have to run a couple of browsers as sites that don't do well on one often are OK in another.

Your machine has an AMD graphics chip. @The other people noticing slow performance in Iceweasel, do you also have AMD graphics?

I don't have any PCs with AMD GPUs currently, just nVidia and Intel.

I have the same problem (Intel chip set).

Mine seems to be mainly associated with an error:
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory.

The error is caused by a program I installed and when removed improved the situation markedly. However, I installed another app for which libvdpau was a dependency and it has been reinstalled.

Seems specific to Iceweasel, because Chromium doesn't do this (version 37 without the hotword bug ).

If you start iceweasel from the terminal (in regular and --safemode) do you see error messages?

Same here on a quite recent machine. It's not up to 100%, but it's laggy.
What I do: I run the mobile version
m.facebook.com
which isn't as comfortable to use, but covers all my needs.
Having the noscript plug in installed also makes it a bit more speedy.

[Danielsan]

I would confirm the same issue and it is very pretty annoying.
With just 3 tabs open and the CPU rises 100% and browser is completely blocked.

Since the 34 version Iceweasel is began always more useless, untill I can use only Chromium or Midori.

I don't have the problem but I have seen it. Try disabling all extensions. If it helps, turn them on one at a time. If that doesn't show the problem, rename ~/.moxilla.

One comparison I use to test is the Tor browser. I also use live-CDs. These don't have my personal attention so if they work better I know I have configured stupidly.

[Danielsan]

I did, all the test, changed the profiles, reseted all the configurations, deactivated all the plugins, the result is even worst As a matter of fact the aim of my extensions is to reduce the consume of CPU, only with NoScript the browser goes fine but the navigation is for me impossible. I knew the problem is javascript and the bad way as javascript is implemented in most of the internet pages.

[thanatos_incarnate]

It's also the fact that Mozilla thinks it's 2003 and we don't need proper multithreaded browsers and per-tab processes.

[Danielsan]

You're right... So, which alternatives to Chromium and Firefox?

[rhy7s]

Since Iceweasel's been updated to version 39 the problematic sites no longer peg the cpu but still cause a regular oscillation of cpu frequency from idle to full speed for me.

[Ardouos]

You're right... So, which alternatives to Chromium and Firefox?

Arora maybe or Opera if you don't care about having a completely free system.

[Danielsan]

@ rhy7s

I will try IW 39 to see if the performance are improved.

@ Ardouos

I like use free & libre software generally, even more if the software is a web-browser!

[thanatos_incarnate]

Sadly. I don't know of any other browser that will give you better performance through multi-threading etc. There are a few of them that are much faster when using simple web sites (Midori, dwb, luakit), but they equally suck for jscript heavy sites. Chrome is sadly the fastest option that I've come across so far. It uses your resources, but it does so quite well.
