Could not make it work Rated 2 out of 5 stars

Not at all useful. Installation was easy but that's it.
Could not debug anything.
Didn't accept Breakpoint settings
"Continue" and "Step In/Over/Out" always greyed out.
Halted arbitrarily during execution.
Screwed up Browser.
No info, No docu, No help
Not intuitive
Waste of Time !
