This especially on iOS (don't know how things are in Android), since I hate it when I click a search result or open a pasted link, and an app opens up when I just wanted to view the page.
For example DuckDuckGo has this in their iOS browser as a simple toggle. That can be used as a reference point on how I'd hope this to work.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
I will not use firefox on iOS until it STOPS opening up links in apps. Example: clicking a linkedin profile opens up linkedin. Thanks but no thanks for letting people know I viewed them.
