I want more than 8 Quick-Links on the Edge homepage.

It is in testing according to a reddit post and in canary/dev. Soon to Stable. They test stuff in those before rolling to stable.

Firefix and other browsers manage.   Hopefully if it is included as an OPTION, users can choose up-to the maximum allowed and control the clutter themseves.

I have submitted this as formal feedback, I hope more people do so.

Yep, it's one of the most requested features, and if you check the Top Feedback Summary at the top of this forum, you'll see it's already in the works:

Planned	Allow more top sites on the New Tab Page

The more users who request it by submitting feedback (Alt-Shift-i in the browser), the faster it will go.

I submitted a request, too, but I'm not sure I have much faith that this sort of feedback gets much attention.  It's actually really pretty important to me, as it's critical for my day to day browsing.  I'm giving Edge a trial run to be my daily driver, as I'm getting tired of how Chrome manages (or rather, fails to manage) memory properly, but they're on at least a 90-day probationary status with me!

I cannot understand why Microsoft have limited the number of Quick Links able to be displayed on the home page to  eight. I have been using Firefox for several years and found that with up to 16 available, I can cover the the sites I uses regularly (although I don't use all 16).

To not even, say, allow an option to increase the number seems to be unnecessarily  controlling/limiting.

I have submitted this as formal feedback, I hope more people do so.

Yep, I'm in full agreement.  Hope Microsoft monitors these request posts.  Pittsburgh, PA

It is planned in the roadmap for December in the insider channels.
