Multi-Browser Preference Saving System

I am in need of a system that facilitates preference saving across multiple browsers used concurrently on five different laptops. All of them operate on Windows. The primary use of these browsers is identical, and their unified functionality is crucial to my operations. The developed system must interact competently with APIs, as the drop-down and radio buttons within the browsers are primarily configured to connect through them. Here are a few key points that freelancers should take note of: currently iam using a tampermonkey extension with dropdown and radio button javascript .but in all systems every day changing in al laptops so i need to connect with server api find the 1st document loaded in 5 laptops and click that radio button which saved in server. 2nd document 2nd saved pref etc. - Develop a system that can handle up to 30 different browsers. - Ensure efficient operations across all browsers, maintaining uniformity in function. - The system must be able to save preferences (Preference 1, Preference 2, Preference 3, Preference 4, etc.) on different servers when selected through drop-down and radio buttons. - The system should be Windows-compatible. Ideal candidates should have demonstrated experience in multi-browser operations, Windows system configurations, and advanced API interactions. Proficiency in developing preference saving systems would be an added advantage.
