gov.uk vehicle tax payment page

[G109B]

I completed the procedure no problem for my car, but could not repeat it for my wife's car.

The problem was on the Payment page where the card number and security code boxes were greyed out and could not be completed. I tried making changes, including re-starting Firefox, to no avail. I had to use Google Chrome to get the job done. This does point the finger at Firefox.

Firefox 128.0.2 (64bit) on Windows 10.

It sounds like the issue is browser-related. Sometimes Firefox blocks certain payment fields due to security settings, extensions, or cached scripts. Since it worked in Chrome, the problem is likely compatibility or a temporary script conflict in Firefox 128. If you're checking fines or completing payments related to Simit por placa, make sure to disable extensions, clear cache, or try private mode before switching browsers. Some platforms are not fully optimized for every browser version

It does sound like a browser compatibility issue. If the payment fields were greyed out in Firefox 128.0.2 on Windows 10 but worked instantly in Chrome, the problem may relate to cached scripts, extensions, or stricter tracking protection blocking payment elements on the GOV.UK page.

Try clearing cache, disabling add-ons, or using a private window. For tracking official process updates, services like Buscador De Estatus can also help verify status information efficiently.

That sounds like a browser compatibility issue. Glad Chrome worked in the end. It's always useful to double-check important vehicle services, including a uk mot check, when experiencing online portal problems.

Es curioso que haya tenido ese problema específico con Firefox, ya que los scripts de validación en portales gubernamentales a veces son muy sensibles a las configuraciones de seguridad o a conflictos con la memoria caché del navegador.
Gestionar formularios administrativos digitales es un desafío constante. Por ejemplo, en Colombia, muchos usuarios reportan dificultades similares al intentar acceder a registros públicos; frecuentemente, los campos de entrada para el runt placa no responden correctamente si hay un conflicto con el navegador o si el formato de la entrada (como añadir guiones innecesarios) interfiere con el script del sitio. Generalmente, limpiar la caché o probar en un modo de navegación limpio suele resolver estos bloqueos en los campos de formulario.
¿Ha verificado si algún complemento de privacidad en su perfil de Firefox estaba bloqueando el script de la pasarela de pagos? Sería útil saber si este es un problema de compatibilidad recurrente en ese portal específico del gobierno.
