According to top, plugin-containe is eating more than 120% of my CPU? I expect that that is allowed because I have a dual core CPU. Firefox is sloooooooowwwww. I expect that plugin-containe... is running in a firefox tab. How do I non-destructively discover which one? I'm running CentOS 6 and firefox 24.8.0 . I haven't updated firefox in a while because I've read that doing so will cause me to lose all my tabs. I'd like to keep them for a while. There is rather a lot of them Is there a way to tell firefox not to run a plugin unless its tab is currently selected? -- Michael hennebry at web.cs.ndsu.NoDak.edu "SCSI is NOT magic.
