Out of nowhere this started happening for me too. In both Edge and Chrome and on different machines, also in private. Consistent on all configurations.

I'm not even a web developer and certainly haven't set any break points. I'm having a sign in issue on a third party website and wanted to send them the HAR file.

This was annoying as as fuck, so thanks @Devip for the workaround though I hope this gets fixed because A) some people probably won't want to turn this off since they actually need the jump to break point and B) I frequently use DevTools to debug stuff on various machines and definitely don't want to first configure it on every browser on every machine I ever use.

It's annoying enough that on Edge it doesn't just open by default any more, and instead asks you if you really want to open it, just annoying Microsoft crap as always...
