Firefox updated to 89.0 today, and my newtabpage looks odd. The shortcuts now have really small previews, as shown in the attached image. How do I get them to be full size again (i.e. fill the box)? It was easier to tell them apart at a glance before the update, post update there's too much empty space. Is there something in about:config that controls this?

Thanks in advance!

I recently updated Firefox to version 89.0 which made my tabs curved rather than square/blocky. Is there any method to revert the look of my tabs? This is strictly for aesthetic purposes.

After updating to 89.0 on Windows 10, I don't see a speaker icon on the tab that's currently playing audio unless I hover over the tab. In to previous releases, any tab that was playing audio had a speaker icon that showed you which tab(s) are playing.

I REALLY dislike the new bookmark pull-down feature, which has larger fonts and far too much space between bookmarks. Now I have to scroll (for which I can't use the mouse) to get to the bottom of a long bookmark list. I prefer older versions.

How may I change the appearance of this feature?
