Extension not working on pages with frames
We maintain a legacy system built with html frames. Like many other Chrome extensions, yours doesn't work at all in case of frames. Too bad, really like your service!

Thank you for your kind words. We're working with limited resources to maintain and improve Damn Bugs so we're aware that it's not perfect or well-suited for every type of situation.
I don't think this is a particular situation that it would make sense for us to spend a big chunk of time trying to accommodate given that frames are intended to disappear - I will however ask the developer if he has any thoughts.
Sorry about your legacy system. :-)
