How Adblock Plus Firefox add-on affects ProjectOffice.net usage?
Adblock plus Firefox add-on might create an error in loading some script elements, for ex. calendars in the task section, Projects & Tasks Module. It is recommended that this add-on be disabled for www.projectoffice.net. There is no need for a complete un-installation; however, a restart of the browser is required after the change in the Adblock Plus settings.
