Supported Browsers

Slipmat needs a modern browser, usually one that is less than 5 years old. If you see an error about browser support, use a newer browser. If you are unsure which browser you have, you can visit our Browser Info tool that tells you the exact version and other public info about it.

For the technical details, see Vite Browser Compatibility.

Slipmat saves website data (localStorage) in your browser. If you see an error that says that localStorage does not work, your browser blocks all website data. Follow the steps for your browser, then reload the page.

Strict privacy settings work fine with Slipmat. Tracking protection and blocked third-party cookies are fine. Only a setting that blocks all cookies or all site data stops Slipmat working.
