In the first place I thought that the problem was connected with the OOPP so I changed the values dom.ipc.plugins.* to false in about:config but the problem was still there.

I tried even in safe-mode but the problem is still there.

(Maybe with only 4 tabs the problem is not so evident but with 25 is very inconvenient)
Summary: [OOPP] plugin_container use a lot of memory with high CPU → Memory leak and high CPU usage

Are you sure of those steps to reproduce?  Is that all?  Do you have to view streaming video to reproduce the problem?  I see no problem here on XP.

Cannot reproduce any bug.

Reporter acknowledges at that memory levels out with time.  VM levels out around 80 MB on my computer (930 MHz P III with 384 MB).  Web site has busy scripts plus feeds.  CPU levels out around 20-50%, but Chromium also uses 30% on my other, much faster Ubuntu computer.
