IE Developer Tools breakpoints are not working

Question

I'm trying to debug some javascript in IE 11 and I'm not able to force it to stop on a breakpoint.

debugger; line works fine (stops debugger in that line), same file without a debugger; line but with a breakpoint set in the same place does nothing (function works fine, but debugger does not stop on a breakpoint).

Chrome's and Firefox's debuggers stop on breakpoints in the same places.

Any thoughts what could be the cause of this behavior?

Solution

Hamlet, in the comments to OP question, gave the correct answer.

Uncheck the following option:

Internet Options > Advanced > Disable Script Debugging (Internet Explorer)
