It is a very helpful add-on, but it blocks the websites' integrated comments widget, which, while planned for, I find a bit annoying.

Allowing the user to temporally put websites into the Facebook container for that may solve the issue.

Seemed to make Facebook quit hanging browser - nice! But feature went away today want to reload it (get Download failed. Please check your connection.)

Great add-on, thanks! You might want to add https://careersatfb.com to the scope also. Thanks!
