[small tip] in case of Firefox' freeze

I just noticed that Firefox froze. 'top' told me that process plugin-container ate all the CPU. 'ps -Ao args|grep "plugin-container"' returned:
/usr/lib/firefox-21.0/plugin-container /usr/lib/mozilla/plugins/ -greomni /usr/lib/firefox-21.0/omni.ja -appomni
So in Firefox' menu I found Tools => Add-ons => Plugins and disabled Shockwave Flash.

PS of course other plugins could be involved, so you'll have to check which one is in each case.

EDIT. And yes, I know that "flash is bad", but that's not the point here.

Install the NoScript Firefox extension and configure it to prevent flash even on trusted sites.
This way you can Click to enable only the flash frames you want to use.

+1 noscript. You should have it installed anyway, since it also provides many other protections than just controlling plugins.

Also, if you start having problems with a plugin, open up a terminal and run 'pkill plugin-cont' (you only need a partial string match). This will terminate the container process without affecting the rest of Firefox. Reloading the page with the plugin object will re-launch the container.

I also use NoScript in Firefox with many other security/privacy related plugins.

But if you want some basic and on-the-fly Flash activation, you can toggle the boolean "plugins.click_to_play" in about:config.
