  As a browser extension, functionality may be limited to specific browsers, which could exclude users who prefer or rely on other browsers not supported by Powerfill.io.
• Privacy and Data Security Concerns
  Storing personal or sensitive information within the extension for autofill purposes raises potential privacy risks if the data is not properly encrypted or protected.
• Limited Complex Form Support
  Highly complex or non-standard forms with dynamic fields, CAPTCHAs, or multi-step processes may not be fully compatible with automated filling, requiring manual intervention.
• Dependency on Extension Updates
  Compatibility with websites can break if the extension isn't regularly updated to handle changes in website structures, leading to potential failures in autofill accuracy.

• Internet Dependency
  The platform requires an internet connection to access the lessons and exercises, which can be inconvenient for users with limited or unreliable internet access.
• Limited Language Support
  The primary focus is on JavaScript, which may not benefit learners looking for comprehensive training in multiple programming languages.
• Self-motivation Required
  As an online learning platform, it requires a high level of self-discipline and motivation from learners to complete the course without the structure of a traditional classroom.
• Pace of Learning
  Learners may find the pace either too fast or too slow depending on their background and prior knowledge, as it's hard to tailor the content to every individual's learning speed.
