What frustrates web developers? Web browsers
Developers surveyed by Mozilla in the second half of 2019 about their experiences with the web platform, tools, and capabilities were mostly satisfied, but they did cite some shortcomings, particularly issues with browser support.
Overall, 59.8 percent reported being satisfied with the web while 16.3 were very satisfied. Only 6.8 percent were dissatisfied and 2.2 percent very dissatisfied. These findings were part of the MDN Web DNA (Developer Needs Assessment) Report 2019, which draws on input from more than 28,000 web developers and designers worldwide.
