I am getting this error TypeError: sections is undefined in section-config.js:50:30 in firefox but not in chrome. I added

<referenceContainer name="content">
    <block name="customer.section.config" class="Magento\Customer\Block\SectionConfig"
    <block name="customer.customer.data"

But still, I am getting that error. Please help me how to solve that.

It might be a browser cache issue. Please try to remove your browser cache and see. Still, you are facing the same error then you have debugged in customer-data.js and see which section is throwing an error.

Hope this will help you.
