The thing I love the most about Sentry/Bugsnag/Honeycomb/etc is that it is essentially automated observability. That is, I don't need to do a huge amount of integration to have, basically, a prioritized list of bugs along with severity and overall application health.

I like the idea of the browser extension being able to offer these kinds of tools where you wouldn't need to install a heavy Javascript snippet -- but I do think that taking the manual steps out of debugging wherever you can is the most efficient. With Bugsnag et al, I don't need to wait for a user to contact me. I shouldn't have to wait for someone to submit a Jam report in order to see how healthy my app is.
