color color contrast on wordmark in dark mode on the about screen is low

Hi, Thank you for reaching out! While I can't reproduce the issue ("Firefox" font color is white for me), I'd like to ask you to [https://bugzilla.mozilla.org/enter_bug.cgi file a bug on Bugzilla], Mozilla's bug tracker, so that the developers are aware. When filing a bug, please specify your phone model and manufacturer, as well as your Android version. Also, attach the screenshot you shared and post a link to the bug here once it's submitted. Thanks in advance!
