If this is still an issue for anyone who is running the latest and greatest version of Firefox etc and has stumbled upon this needing a quick tip, there is a bit of a messy workaround for this issue:
The plugin-container is designed to contain crashes from plugins like flash and stop them from crashing the browser along with them. Flash may crash even nowadays (I find it surprising given how long it's been out and how employed it still is! It is still being updated now and then and html5 has yet to be fully implemented across youtube etc (usually because of it impeding advertisements)). The plugin container can be disabled if you are prepared for the chance that a stray flash application can inadvertently crash and take the browser with it (annoying), by doing this: Go to the page "about:config" in firefox Search for a boolean entry named "dom.ipc.plugins.enabled" and double-click it or otherwise change it so that it reads 'false' instead of 'true'. The next time firefox is started (close it and open it back up or restart it - there's an addon called "restartless restart" which is amazing for this), the plugin container will be long gone. Set the entry back to true to reenable the container, but if you're prepared for the possibility of grief from crashing or you never bother with flash things anyway, then perhaps this will be useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/635023 Title: firefox plugin-container using 99% CPU - overheating and lock-up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/635023/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
