Anyway I finally got the answer. I was looking into these lines, however the 4th point sorted it out.
- web-browser associated with html files. File -> Right Click -> Open With -> Change All…
- If web-server is specifying the type of browser by some preference.
- If lime-tools ProcessHelper was somehow launching it by some preference
- The OS’s choice of default browser.
Changing the default browser for the OS will change the default browser. On Mac it can be changed here
