Whats the solution for the busy engineer? Anyone know a Selenium plug in that let's you run with browser extensions or something? There's too many popular extensions to test manually.
Haven't seen this automated, but I have seen internal issues raised by folks within large orgs when their extension started breaking things. But it's only once you have 50+ to 100's of engineers working on a product, each with a subset of extensions installed, that you can rely on the cross product of engineers and their installed extensions for realistic coverage.
