ubuntu 15.04: firefox freezes, plugin-container using 90% CPU, 11GB RAM

Posted

Every now and then (maybe once a week on average), Firefox suddenly freezes, and checking 'top' shows that the plugin-container is using 90%+ of both CPU and RAM (I have 12 GB of RAM). So I kill firefox, and when I restart, it is running as normal again.

For extensions, I only have LeechBlock (and Ubuntu Modifications). For plugins I have Flash, Java, OpenH264 Video Codec, and iTunes application detector (apparently). Flash and Java are both up-to-date.


Since the problem happens somewhat rarely, I haven't been able to reproduce it or track down any kind of cause, but I thought it merited reporting anyway; a web search didn't seem to show anyone else reporting the same problem.

FredMcD sure if the OP was using Firefox on Windows and not on Linux as only your first link is applicable.


The Flash Player and or Java Plugins may be culprits. You should set them to "Ask to Activate" so they will only run when you allow.

I have a pretty beefy Linux system myself (i5-4690k and 16GB Ram) and I find setting Flash Player at "Ask to Activate" can still make a big difference as Flash videos and Ads will not play unless allowed.

Keep a record. What you were doing. What the browser was doing.

check this:

  • see if there are updates for your graphics drive drivers

https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

  • disable hardware acceleration in the Flash plugin

Java was already 'ask to activate'; flash was not. I have set it to be. I looked into updating drivers, but I believe mine are up-to-date. If the problem persists after my flash change, I will make sure of that.

Thanks for your help! I'll report back.

Since switching Flash to 'ask to activate', the problem has not reoccurred for me.
