The 'add "outlook.live.com" as an application for mailto links' keeps popping up continuously after I click to X to delete the banner message. How do I disable it? Firefox should have a "don't remind me again" option. I do not want to add mailto links or make any changes. Thank You!

In Chromium you can go a page backward or forward by swiping one finger to the left or right. This works really well. I have been missing this feature in Firefox for years now. Without it navigation in the browser is tedious on Linux tablets or phones.

Is something similar ever going to be implemented?
