I've lost the ability to add new sites, change display size, etc. of sites shown when I open a new tab. What am I doing wrong?
At some point my ability to add sites from the new tab page, change site displayed sizes, etc. has stopped working. I liked this feature. What changed or what am I doing wrong?

Having more than one version of a program may cause issues.

Do you still see the about:newtab page with the 3x3 tiles?
Did you modify the number of rows and columns on this page?
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
