Instagram is a very popular image sharing service which allows users to share their photos instantly to Facebook or Twitter by adding selected filters. Ever since the release of Android version of Instagram, the app has become even more popular. The main problem is that you need to have a phone to view your feed since Instagram does not have a web interface although there are third party alternatives.
You can view the feed of your Instagram along with the profile. There is no option to like or comment on photo, but you can view all of them in your feed.
Instagram for Firefox is a restartless extension, so you won’t be required to restart the browser in order to enjoy its functionality.
