This began to happen occasionally and it seemed that clearing the browser cache and restarting it solved the problem, but now it doesn't works and it makes no sense: I can have 150 tabs open just fine and next session it crumbles and uses all 4 cores at 100% with >10 tabs open.
Both Chromium and Iron are working fine without any of these issues, could it be the chrome install is corrupted? how do I reinstall it without losing all my app configs?
Any idea what could be causing this?

chrome --disable-extensions? Does the problem occur again? – maggotbrain Jan 17 at 5:06
