Quick to uninstall it maybe
.... no auto update, extension crashes, browser crashes, sluggish all round. Probably the worst version I've tried but never mind, it's beta software so it can't all be plain sailing - and looking at comments on their blog, I'm not the only one. Previous version was a bit sketchy for me as well.
I'll wait and see what happens. I'm sure they'll sort it out. Browser's virtually unusable for me at the moment though.
