You can do that in IntelliJ. If there's a way to control a tab on a browser you could do that too. When I was writing my thesis, I would have `inotifywait` running on one side and when it detected the file had changed it would run the entire `pdflatex` + `bibtex` pipeline the 6 times or whatever it needed and Evince would hot-reload so I had a live preview. I'm sure a browser can do the same with some command.
