Hate the rounded corners inside firefox. Disabled them in windows 11 a long time ago, now you have them inside firefox itself.

Is the rounded corners inside Firefox something new? Got rid of them in Windows 11 like a lot of people do and keep them square again after updates and here you betray me. LOL.

The dreaded rounded corners are back, what a burden to have to research and find out how to disable it. Why don't you just give us that option? I can not accept the rounded corners AT ALL. Thank you for listening. I have a lot of other things on my mind, but have to spend no telling how long to figure out how to get rid of those rounded corners.

Hello

Have you tested.

/* In userChrome.css */ :root { --border-radius-medium: var(--border-radius-small, 4px) !important; }

Have you tested.

/* In userContent.css */ @-moz-document url-prefix("about:"), url-prefix("chrome:") { /* Firefox pages like settings etc. */ :root { --border-radius-medium: var(--border-radius-small, 4px) !important; } }

Have you tested, userChrome.css and userContent.css, together.
