Frequently Asked Questions
SupaSidebar FAQ
Is SupaSidebar a browser extension?
No, SupaSidebar is not a browser extension! It is a powerful, standalone native application for macOS that lives in your menubar. It integrates with your browsers through secure, native methods to read and save tab information, but it operates independently as its own app. This means it can also manage files and folders from your Finder and work globally across your entire Mac system, not just inside a browser window!
Which browsers does SupaSidebar work with?
SupaSidebar offers fantastic compatibility and works seamlessly with all major browsers on your Mac! This includes Safari, Google Chrome, Mozilla Firefox, the Brave browser, and the popular Arc browser. The app is designed to be your universal companion, so no matter which browser you prefer for different tasks, you can save links and access your sidebar content consistently and without any hassle!
What macOS version do I need?
To run SupaSidebar and enjoy all its powerful features, you will need a Mac running macOS 13 (Ventura) or a newer version. This ensures the app can utilize the latest macOS technologies for performance, security, and seamless system integration, providing you with the smooth, native experience it's designed to deliver!
Where is my data stored?
Your privacy and security are paramount! All the data you save into SupaSidebar--your links, your file paths, your organizational spaces--is stored locally and privately on your own Mac.
