It's something I noticed especially when they switched to React. A few examples I frequently experience:
1) Stepping through TS frequently switches back to the source JS. 2) Breakpoints don't always go away, and sometimes a page reloads with an invisible breakpoint, that stops the code, but doesn't show up in the list of breakpoints, and doesn't seem to be removable. 3) Breakpoints don't always stop at the the right place. 4) After having the tools open for a while, the tab starts freezing for multiple seconds every few seconds (GC, according to the perf tab, so it's either my code or the dev tools)
This comes from a place of love, and I'll still always use FF over Chrome, but I really have to ask if anyone else experiences the same issues, or if it's perhaps my setup/code that causes the problems?
