Hello I love Firefox and I primarily use Firefox on all my devices. I manage facebook and instagram account using facebook content studio. I have no problem uploading videos to facebook. I upload the videos to Instagram from this link (https://business.facebook.com/creatorstudio/instagram_content_posts). I'm not having a problem uploading a post(image). but I'm having trouble uploading the video. The problem I have is: the video upload continues up to 99.9%, but somehow it does not go to 100%. I cannot share the video unless it is 100%. I try again, close and open the tab and sometimes even restart the browser. Not all the time but too many times I have this problem. I upload the same video to twitter, facebook and instagram. video uploads to twitter and facebook without any problem, but not to instagram. I wait for a long time, but unfortunately it is not 100%. I have been using the Google Chrome browser for video uploads for a while because firefox has not finished uploading, and I have not encountered any problems so far. I only experience this problem when uploading videos to Instagram and through firefox. I am using Facebook container and Tab Reloader plugins. I also wrote this problem on facebook, but they do not seem to have a problem. please find a solution to this problem. I want to use firefox. not chrome u. best regards
