On my mission to find an extension for every social media website I use so I can retire having the app installed onto my phone, this was the closest I got to making Instagram more usable via Firefox for Android. It gets you pretty close, but there is an issue with the website that's perhaps outside the scope of this extension — remember the position you scroll to when going back from an image on a profile. Otherwise though it does exactly as it says, and overall simplifies your ability to consume content.
