Passive income: NO

Earning passive income solely from building browser plugins is a realistic goal for some, but it's not a guarantee for everyone. The setup cost for this hustle can range from $100 to $500, depending on the complexity of the plugins. To make it more passive, you can automate certain processes like updates and customer support, but initial development and maintenance will require active involvement. While some individuals have successfully generated passive income from browser plugins, it usually involves investing time upfront and ongoing effort to ensure the plugins remain functional and relevant. It's important to note that not everyone achieves a fully passive income from this hustle, as it often requires continuous optimization and adaptation to market demands. Misleading expectations include thinking that once a plugin is launched, it will automatically generate passive income without any further work. Overall, while passive income is possible with browser plugins, it typically requires ongoing effort and may not be fully passive for everyone.
