I'm pretty new to WebStorm and have just set up a basic project with HTML, CSS/Scss. During the last few days, I've just tested the project on Google Chrome and it was working perfectly fine. However, when I try to open it in Safari or Firefox from the IDE, it's not working. Opera, on the other hand, is again working.
I'm getting server not found errors on both browsers. I'm currently working on macOS 10.14. I'm running WebStorm 2018.2.4.
I really appreciate any help. Thanks in advance.
