"Google Rolls Back reCaptcha Update to Fix Firefox Issues"

Google recently rolled back a release of its reCaptcha captcha script after a bug caused the service to no longer work on Firefox for Windows. According to Mozilla, the issue was related to reCaptcha's dark mode detection routine for Firefox in Windows. Mozilla noted that the script attempted to modify a div's background color using "document.body.removeChild", but as the script was loaded in the HTML head, the DOM had not loaded yet and "document.body" was not available, causing the script error. As a temporary workaround, users could change their browser user agent to one for Microsoft Edge and Google Chrome, and reCaptcha would work again. Google has now reverted to an earlier script version, fixing the bug for Firefox users.
