I open firefox and browse through sites. Sometimes, automatically, the cursor stops moving, I can't use the keyboard too and system is hung. It doesn't go to the command line either. I found out that this may mostly be due to a adobe flash plugin. I don't know which one or which one to remove.

Every time this happens I have to manually force shutdown the computer and switch it on again.

I know I've been pretty vague in giving details but I don't know how exactly this problem occurs.

I'm using Ubuntu 14.04.

You resolve problems by trying one thing at a time

Is flash the problem?:

  • disable flash in Firefox
    • go to firefox/tools > addons > plugins and set shockwave flash to ask to activate
  • does the problem still exist?

Is Firefox the problem?

Good luck!

I was having exactly the same problem on 2 different machines I disabled flash on one of them and the problem seemed to go away. Will do the other tomorrow. IMO I think that either Fire Fox is buggy or its the Flash plugin either way it makes for a terrible experience you should not have to disable a plug in to make it stable
