Hi Tim, there will be some changes that are both inside and outside of our control. eg. with Firefox, yes, from Lite Software it will install Snap, and there is a warning for that. In each of the 6x release announcements, there are instructions for installing the Firefox PPA so that you get Firefox the same way as you have in the past.

Video drivers can be troublesome, it's linux and the support and path to take can be a minefield. What works in one series eg 5x can change in the next.

But for every problem, there is a correct path to a resolution. If you ever find something not working the way it used to or as you would expect, please ask us for help in regard to that issue. Cheers
