It only works for a short period of time,then the pop up box, to select the container you want comes up as a blank white box,it happens every time I've loaded it & reloaded it & cleared caches & refreshed firefox & reinstalled all add-ons 1 by 1 & it doesn't matter it always happens & you lose it & all the other mutli acct containers that are based on the same code, so I can't open certain sites now,when the tab is closed I can't go back into container so I can't safely use my social media, thanks, can you fix this shit? asap & I'll change my stars to higher 4 or 5 likely but as it stands I give a 1 star since it's not only unusable it's preventing me from even logging into my social media totally..& safely
