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?

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!

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 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.
