Opening on Firefox 132.0.2 (all extensions disabled) I get a Content-Security-Policy error, on Edge 131.0.2903.51 (stock) in the issues panel reports 40 Errors and 147 Warnings (With Top Browsers selected). Downloading chrome 131.0.6778.86 just to test they also have a different error "Define @import rules at the top of the stylesheet" which specifies that the @import is ignored due to it not being at the top. They're just hidden in the issues, so same as edge.
This might be more down to the browser you're using and not the extensions present (while extensions like ublock origin do cause more errors.) Not even chrome has 0 problems with their own default home page.
