Uploading/posting files via the Firefox browser on my laptop to Instagram does not work. It's been stuck on this window for 15 min (I'm using another PC for other work). The only reason I need firefox is to do this action. I don't want to use IG's mobile app for anything. I don't want to use any other browser because IG has me flagged with other browsers — they included my previous IG account in it's random ban via it's AI clean up of accounts for simply posting photos of surfers at a competition —( but that's for another topic for another day).

Any assistance with this will be greatly appreciated. Thank you and have a nice day! —Steve
