  • Device Connection Limit
    The basic plan allows only up to two simultaneous device connections, which might be limiting for some users.

    ProtonVPN lacks 24/7 live chat customer support, which could be a drawback for users needing immediate assistance.

  • Slower Performance on Some Sites
    In some cases, Firefox may perform slightly slower than competitors like Google Chrome, particularly with sites heavily optimized for Chrome.
  • Market Share
    Firefox holds a smaller market share compared to giants like Chrome, which can sometimes result in websites being less optimized for Firefox.
  • Limited Native Features
    Some features that are built-in with other browsers need to be added via extensions in Firefox, potentially making the setup process longer.
  • Frequent Updates
    Though generally positive, Firefox's frequent updates can sometimes introduce bugs or lead to unexpected behavior, needing rapid release fixes.

    I adore Firefox's functionality and the fact that it is open source software that might be created by tens of thousands of people worldwide. You can utilize features that aren't accessible on rival products like Chrome because it is open source.
