Sorry for the confusion! That is just our tab suspension functionality you're seeing. Our suspended tabs take up essentially no memory as all they contain is redirect (no data harvesting or analytics at all). If you're by chance a developer, it should be very easy for you to confirm that is the case.

Nonetheless, you can easily disable this feature in settings here: https://workona.com/0/settings/suspension

However, once you disable the feature, you'll no longer get the benefits of tab suspension, which means that all of the tabs you have open will be using up your computer's memory.

We originally didn't have the tab suspension feature, and quickly realized that it was an essential feature for a tab manager like Workona. You can read more about the feature and the motivations behind it here:
