Great to see the emphasis on DevTools in this release. DevTools have definitely much improved since I last tried, but they are still glitchy compared to Chrome. For example, I was using the JS debugger, and for some reason breakpoints wouldn't "hold"—after being stopped for some period of time (not long), the page would refresh. Also little things like https://bugzilla.mozilla.org/show_bug.cgi?id=1613957, which I was able to report. It was frustrating. Had to go back to Chrome for development. Still, it was nice to see many features that Chrome doesn't have, like breakpoint logging, which is nice when you want to insert a log into third party code.
And as a browser from a non-dev perspective, it's great. Great to know this browser is all about privacy instead of just trying to provide the bare minimum to keep people on board. Great to have the Facebook Container.
Thank you Firefox!
