The spacing between thumbnails for the New Tab feature is too tight. We should explore doubling the spacing between the thumbnails. Tim and I have talked about moving to a 4x2 grid vs. a 3x3 grid, but would like UX to weigh in on their thoughts.
Please take it to bug 455553, which hasn't landed on mozilla-central and is still under development.
I spoke with Tim and we'd like to track changes to the original work separately so it's easier to manage. Thanks.
Why not allow the user to set the number of thumbnails? You can also resize previews as well as in the panorama.
We can also resize groups in Panorama, and this can be applied to new tab page also. But why do we block the new tab page from landing from m-c for such cosmetic issues.
Tim's working on a few other fixes and needs his code reviewed before landing it on m-c. This bug is by no means a blocker for nightly, but given the volume of how many new tabs are spawned per user per day, we want to get to a point where basic functionality was there and we could receive feedback.
In addition, we should also have a boundary around thumbnails, currently it is not possible to distinguish thumbnails of pages having white background from the new tab background.
3x3 grid is what we want, since humans in general work on a 7±2 item perception threshold. If people want infinite customizability here, they should get an add-on. I do agree that the current visual setup isn't optimal, and the thumbnails should work better with wide or tall windows. Boriss will be your guide to the exact dimensions and spacing needed here.

The thumbnail grid container has a fixed height which is larger than what is needed for the grid. So in a restored window a vertical scrollbar appears although there is enough room for the grid.
The thumbnails are certainly too small on larger monitors, it simply leaves too much white-space.
