Fóram Tacaíochta Firefox

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.

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.

How to remove the search bar above the URL line?

This seems to have been added very recently. Can not find any way yo to it thru Settings, etc.

Thanks, Jim

The new update has changed the way my homepage looks. I want it back the way it was with the same colors. The most important part, my shortcut squares are too small. I'm old and need them back to the size they were.

I can't find a way to make them larger. Can anyone help?

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?
