Ctl-B in Facebook

In Firefox Ctl-B is the default key to open the Fireox Bookmark panel. Facebook has now overridden that so it now opens a dialog where you can give feedback to Fadebook. Is there some way to change it back on my PC?

If you’re okay with prioritizing all Firefox’s shortcuts over Facebook’s do this while on the Facebook page: Open Page Info (should be ctrl-I) go to Permissions, and then uncheck “Override Keyboard Shortcuts” and choose “Block.” That seems to do it for me on my end.

Thank you!!!

This was supposed to be in general questions, but I guess it doesn’t matter now.
