It seems to be a new Chrome update. Just after the last update, Chrome turned off the BPiP extension and asking permission to delete them.
But for now, it is possible to add it manually in developer mode, and it is working.
The manual method is also just a temporary workaround. It may be disabled in the near future
I have been moving round trying to use the manual method still do not work, what I did was to delete it to see if I could download it back (add) but it refuses. Seems there is no hope for that, I am only window store now downloading my firefox to see if I can use it on that browser.
