I want to replace chrome with firefox. But as a student the most common features I use is to save/download the offline webpage. This feature is not present in firefox. It is one of the basic features which a browser should have.
You can save pages to Mozilla's Pocket feature for later reading. (Look for "Saves" tab in Pocket.) However, personally, Pocket disappoints me because of the unmanageable clickbait "suggestions" that appear on the home screen ("Pocket-Worthy Reads", "Popular Collections", "Today’s Pocket Hits", "Recommended Reads", "Life Hacks"). Pocket is bad for me if I can't clear the Home screen; I'm very distractible and the LAST thing I need is such distractions when I'm trying to get something done. But it might work for you.
Please add a feature to save pages for offline viewing and reading. This is a very helpful feature that I can not use a browser without it. But apart from that I've used firfox for about a week and I love how it works
