First things first, I use both Chrome and Firefox on Windows 7 and 10. Either a Greasemonkey/Tampermonkey script, or an extension for one or both of those browsers, would be fine as solutions.
Instagram on the web uses an infinite-scroll mechanic to only load a certain number of images at a time. Currently, if I want to view all images on a single user's page, I have to sit and hold the End key for as long as it takes the page to load. (Or put a rock on the key, but that's not really elegant either.)
What I'd like is a script or extension, activated by a key combo (Alt + G or whatever you care to make it), that will automatically scroll an Instagram page until there are no more photos to load, at which point it should stop executing. That's really pretty much it. Bonus points if it does the same for other "infinite scroll" websites, but that's not in any way a requirement -- the goal is to do this for [login to view URL] on a desktop browser.
I'd like this as quickly as you think you can get it done, so I will favor bidders who are able to start immediately. If you have any questions, please don't hesitate to ask. Thanks for bidding!
