Are desktop extensions supported on Android?
Currently, only extensions that have been adapted by their developers for the mobile version of Firefox can be installed from the official store on Android. While there are methods to install some desktop extensions using beta or Nightly versions of the browser, these procedures are not recommended for everyday use due to their instability and potential security issues. It is recommended to choose only officially supported Android extensions and stay informed through Mozilla about new compatibility updates.
Why does Firefox allow extensions on Android but Chrome doesn't?
One of the most frequently asked questions is why Firefox supports extensions on Android and Google Chrome doesn't. The answer lies in the philosophy of both browsers and Mozilla's open-source approach. Firefox has opted for openness and customization, allowing developers to adapt and publish their extensions for mobile devices as well.
In contrast, Google Chrome maintains a closed ecosystem in its mobile version , preventing the installation of add-ons for performance, security, and consistent user experience reasons. Therefore, if you're looking for a desktop-like experience where you can install and modify extensions to your liking on Android, Firefox is the more advanced option.
