I am using Angular 6 and aggrid to display a larger dataset with > 500 columns which shouldn't be a problem. When loading the grid with Chrome it takes a moment but it doesnt freeze the UI. You can still click and drag on the website. Firefox on the other hand freezes completely for nearly 5s. I can't figure out which code is causing this.
Is there a way to monitor what is causing this? Maybe with the firefox devtools?
