We support pretty much all the modern browsers with some exceptions. Any browser based on the Chromium browser is supported as they are just Chrome under the hood. This includes Firefox, Edge and Opera. Similarly you can use our extension on forks of Firefox such as Librewolf, Waterfox, etc.
The only major exception to this is Safari and this is due to Safari limitations, not our own. We'd love to offer an extension for Safari but the functionality of our features is not supported in the browser unfortunately.
