Can you enlighten me what's the thing with the developer edition?

It seems to have features that the standard edition doesn't have. But does the standard edition have feature the dev edition doesen't?

Or are there some different features? Any of them reason not to use the dev edition in daily browsing?

Dev edition is regular Firefox beta with some other defaults (theme, developer options). The only reason you might not want to use it is because the stability guarantees are less strong than for stable, but in practice, it probably runs stable enough.
