If you are using Firefox as your standard browser, no worries here. eyeson works perfectly fine with this browser 😉
In case you want to share your screen, Firefox handles that a little bit different compared to Google Chrome. Whereas you need to add an extension when you want to share your screen in Google Chrome, you do not have to do that in your Firefox browser. You only have to Allow Access when it asks you to do so.
Screensharing is already supported by Firefox, therefore there is no need for a plugin.
I hope everything is clear so far 🙂
