In-browser editors are OK, if you can test your work without disrupting the connection, yeah. So sometimes if e.g. the website you're building is in another browser tab that has been enough.
The other way round -- an in-editor browser -- could be the better way to work. GoCoEdit does this (and it really is rather good!) as does Panic's Code Editor (formerly Coda for iOS), which is good, but not as good. And you arguably get a terminal more easily this way too, particularly where SSH keys are involved.
