Kind of unrelated, but I was thinking about these companies making SaaS as browsers extensions for a living. I mean, when you see the whole add-ons system from Firefox being reforged, it just feels extremely unstable to build a business on this. What if tomorrow, a new browser arrives, get a huge part in market shares but has no extension system so you can edit the content/DOM of pages as much as you want... You are screwed.
