I always used to use the Firefox browser, but for the past couple of years I've mostly been using Edge because I can pin videos to the taskbar. I don't like cable subscriptions, so my biggest source for getting news is YouTube. Since I can't spend all day looking at videos, I pin the ones I want to come back to on my taskbar and can quickly access one or two when I have time. This is a MAJOR part of my ability to function and get the information I need. I would completely abandon the Edge browser if Firefox had this functionality. I am tired of the MSN click-baity biased news feed that serves as Edge browser's landing page, but I NEED the functionality of being able to pin videos and other websites to streamline my day.
My other frustration is that I had to join a platform and check for an email and do all the things that most people won't do to tell Mozilla that this is important to them. Most people will just use another browser.
For me, exactly like Edge or Chrome at least. If it is a video I am pinning, I would like to retain the video at the point I left off on that video without having to do a special save that takes more time. If there are any features Mozilla could think of to make any of this even quicker or easier, that would be a plus.
