Hi, I have this problem, in dev tools debugger, the I am unable to add a breakpoint to javascript code . through trial and error I have found if I refresh the page while devtools are open and after page loading I try to add breakpoint to any javascript file or in page javascript. it does not work. break point is "not" added neither by clicking on edge nor by the right click menu.

but if i close the dev tools and then refresh page and then open dev tools and add break point same as above. It works and breakpoint is added.

I have tried it in safe mode too. its the same.

Hi Ali, there is a similar thread going on the DevTools forum, but I think your description is more specific:

https://discourse.mozilla.org/t/cant-set-debugger-breakpoints/33972

I can't tell whether this particular issue has been logged in Bugzilla, the bug tracking system, because there are a large volume of recent results when I search for debugger breakpoint in open bugs:

https://bugzilla.mozilla.org/buglist.cgi?quicksearch=debugger+breakpoint

Do you want to follow up on Discourse or file a new bug?
