Firefox version 157 is round (and how to make it less round)

I added

  border-radius: 0px !important;

to my user chrome as per the article, but it didn't seem to accomplish anything. I've restarted with no effect. I didn't have a custom userChrome.css file before, but the instructions were clear enough. Do you have to enable it or something?

Ok, found that you need a setting in about:config

  toolkit.legacyUserProfileCustomizations.stylesheets = true

You also have to toggle "toolkit.legacyUserProfileCustomizations.stylesheets" to true in about:config

I did both. Still round.

Update: I figured it out. The article’s snippet has no selector. As rendered it’s just { border-radius: 0px !important; }, which is invalid CSS and gets ignored (the * was probably eaten by the blog’s formatting). Use:

* { border-radius: 0px !important; }
