I have been using the Developer Edition since 2014, when it was released, without issue. You are not locked into a single browser. Personally I use more then one browser, and professionally I always validate against multiple browsers.
I find different browsers excel at different things in regards to the developer experience. As an example I appreciate that Firefox had a formatted JSON view without requiring an extension. However Chrome also has capabilities that I wish were included in Firefox.
