You mentioned that after you install it and use other extensions, 'the next thing I notice is the whole thing is broken'. Please expand on this a little more so that we have an idea about what the problem is that you are experiencing. With some additional info we can try to reproduce and troubleshoot this issue. If there is a problem that we cannot reproduce quickly on our end I can open a ticket for so that we can check into this with an engineer to try and understand what is happening and get it fixed for you.
