Created attachment 345747 [details] Screen Cast of how the bug happens How to reproduce: 1. Set a breakpoint 2. Reload page to hit the breakpoint 3. Be annoyed when the pane switches to something completely unrelated (sources pane in this case) 4. Switch back to the debugger pane to continue working

Thank you for reporting the bug, Martin. Sources tab is an experimental feature what is unfinished. Currently, the Sources tab is the same as Resources. You have the experimental Sources tab enabled in settings (the gear icon on the top right side of the Web Inspector). This bug shouldn't happen if you disable this unfinished experimental feature by unchecking: Settings -> Experimental -> Sources: [ ] Enable Sources Tab Please let me know if this helped.
Yes, this seems to be a workaround. Thanks!
