The only okayish theme came with Nova. I hate the radius though.

To me, the new Nova look in Firefox 157 is awful. Thank goodness for this theme!

Also, I'm not a fan of the all rounded tab corners, and set browser.nova.enabled to false in about:config

If it weren't for this theme, I would have uninstalled FF 157 because of the new default purple splotched theme.

The only one that looks like Firefox before the update to version 157. Thanks God it exists. I don't know why they change the UI.

Have been waiting for a nice soothing theme for a long time!
