Mozilla blames recaptcha issue in Firefox on Google

[harlan4096]

Mozilla confirmed a recaptcha issue in the organization's Firefox web browser yesterday evening.

Affected Firefox users see a spinning animation when they try to solve the captcha, which means that they are unable to do so. The result is that they cannot access the website or service. A workaround is available.

The issue affects all major versions of Firefox for Windows that are supported  by Mozilla as well as older versions. This includes Firefox 125, the current stable version of Firefox, the development versions 126 and 127, and also Firefox ESR 115.

Mozilla says that the issue is not caused by changes that it made to Firefox. Instead, it believes that Google is the culprit and it makes the following points to back this up:

• The issue affects new and old Firefox installations alike. It affects Firefox ESR, Firefox Stable, and also Firefox releases that were released last year and are no longer supported.
  
• Changing the user agent to Firefox for Linux or Chrome for Windows makes the captchas work again.
  
• Changing the user agent of Chrome to Firefox for Windows breaks the captchas in Chrome as well.
  

Workaround for the Firefox captcha issue



 Firefox users who run into the issue may resolve it in the following way:

1. Type about:config in the Firefox address bar.
   
2. Search for general.useragent.override.
   
3. Switch to String and activate the add-icon.
   
4. Copy and paste the following string into the field: Mozilla/5.0 (X11; Linux x86_64; rv:125.0) Gecko/20100101 Firefox/125.0.
