Look out for addons. Electrolysis will still not work with many of them. I force enabled it a few weeks ago, and discovered that it's disabled for good reasons.

Have about ten plugins, no issues here. It's worth actually having a browser that doesn't consume all available resource.

Nice idea but a load of useful extensions don't work with it. Of extensions I use noscript and 1password were the main ones, but around half were tagged as not compatible.

Heh. Tried that out and while it didn't affect stability it made switching tabs take 2-3s on a haswell system. By disabling all extensions with it I was able to somewhat match performance of non-multiprocess.
