   Once in a while firefox will get 100% processor time and cause the whole system to freeze. The only way to regain control is to hit the reset button. I think this happens when firefox tries to load a page with too many images, but I'm not completely sure. (I think javascript bloatware also plays a role)

   I'm setting firefox's priority to 10 after launching it, but it doesn't make any difference.

   I assumed the kernel had some high priority process that would be able to kill any user process that misbehaved, but that doesn't seem to be the case?

   This seems like it could be handy...

   "The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem."

   ...but apparentely it hasn't been compiled into SliTaz kernel?

   hi folks,

   same problem on Firefox . Sometimes with the 4.0 .. often with the lastest rolling. Both running Live-usb. Have to reboot. It doesnt freeze when 100% but often when many tabs are open

   It's because Firefox cache is messing with the RAM and the RAM-disk of the Live session ?

   Also, it looks like the ethernet disconnects some times with the lastest rolling

   Atom N270 with 1 GB of Ram

   Hi moulefrite

   Try:

   Open Firefox and open url : about:config

   Search for: browser.cache.disk.enable :: value » true
   (!!Double click and change value to » false)

   Search for: browser.cache.memory.enable :: value » false
   (!!Double click and change value to » true)

   Search for: browser.cache.memory.max_entry_size
   (!! Double click and change the value to whatever you want or change to "-1" to automatic.)

   Warning: This method are that your tabs won't survive a browser crash.
   ..

   Thx hackdorte.

   It makes sense as Firefox cache (a) mixed up with the free RAM (b) and the virtual RAM-disk (c) of the live session. Your solution is to put the (a) into (b) in order the limit is never reached (-> no freeze) as the (a) will be dynamicaly allocated

   If official Slitaz incorporates Firefox, this should be a default configuration.

   Nowadays, Internet became a technology garbage full of scripts and analytics. No way an Atom first generation with 1GB can deal with this without freezing when many tabs open.

   Hello, have you verified your hardware with MemTest86 ?

   My laptop was hanging also when CPU at 100 % when a flash application on the browser was using most of the CPU power.

   Launched MemTest86 from Slitaz boot CD and then it finaly freezes after some time so I guess the hardware is the problem. Maybe thermal paste has been getting too old or cooling fan dirty or maybe a RAM problem.

   Appart from that, Slitaz installation was alright and I could use the computer normaly when CPU was not running at 100 %. Because Slitaz rarely use a lot of CPU power.

   Good luck.

    Hi,
    new_u
    Try Pale Moon (based on Firefox), because clear(last editions) of Firefox not for Slitaz as well, its not optimized for system. In my case even repairing about:config does not take effects.

    As for me; I finally unmounted the Laptop (an old core 2 duo).
    The thermal paste was bad, there was also small amount of dust also on the heat pipe.

    Launched MemTest86 again an no problem anymore when CPU is at 100%
    However unmounting this laptop (HP laptop) was not for the faint hearted !
    I prefer to unmount a Dell laptop (easyier better built).

    Notice that the Core 2 duo was not getting very hot however; apparently.
    And that it could run during 1 or 2 hours without problem provided that CPU use was low.
    I have seen the same problem with a Dell laptop but it was switching off instead of hanging like the HP laptop does.

    Currently the Opera browser is very light and functional. Firefox is very slow in the notebook and android arm.

    Opera is fast with new adblocker.

    Hello; as for me I ended up with trying some tricks I can't describe here. Because it is not the subject. Firefox and Linux were alright; it was just that a chip the mobo was dying. Let's keep things calm with Hewlett Packard brand.

    Ironically the laptop was said to withstand military MIL-STD 810F standards !!!

    Ive installed Slitaz 64 rooling on HD, 4GB of Ram

    It happens that my thinkpad x230 totaly freezes even when Firefox is closed (not sure) (an i configure Firefox like describen before) . I have to force reboot.

    Is there any tool which will help me to know where the problem comes from ? I made memory test on Windows and no apparently nothing comes from the memory ..

    I had same freeze issues while playing games on Windows

    thx

    fore me it looks like one ram module is bad (it was also your idea, as you run win memtest) - you should have 2 ram modules with 2 GB - try to start your laptop with only one module and see, if it works better with one of the 2
