This add-on works fine. READ THE INSTRUCTIONS. For videos: right click, open in new tab, choose "download this video", right click video, save as. For images: right click, "save instagram" or right click again, open in new tab, download or copy. Done. Thank the developer.
Can confirm, regardless if this used to work or not, it doesn't work now, as most recent reviews will tell you. I live in the United States, if it isn't working here, as it is for many of the reviewers who gave it a poor score, then where IS it expected to work? I see responses mentioning an issue with region/ip so if that is the issue it certainly isn't any of the users' fault and is certainly an issue with the app. As it stands I cannot recommend this, and Firefox doesn't either.
Update: Version 1.7 fixes that the plugin was not working while logged in on Instagram. Probably that was the case in your scenario.
Today, this add-on has been confirmed to be working in Europe (UK, NL), USA, Canada, and South America (Brazil). Please provide your Browser version and rough geo location for further debugging. This seems to be an issue with different page layouts being served to different regions by geo IP or A/B testing. Please excuse the inconvenience for now.
