time to step down old man

Firefox has been using this logo design before the new Microsoft Edge logo was used

Logo on the top right has never been used as a logo for the Firefox Browser. It’s used for the Firefox brand of products

The last one is not the Firefox logo. It’s the logo for the “Firefox Brand” of products (Which includes Firefox, Firefox Monitor, etc.) Firefox the browser uses the second to last logo, and I honestly think it looks pretty good?
