The default value is not applied to all opened tabs automatically. Rated 4 out of 5 stars

When many Firefox tabs are opened, the default FullZoom value is not applied to quite a few. The only way to solve that is to left-click your taskbar indicator and press reset. It should be done automatically to say the least.

Hope you solve this serious problem.

Thanks for sharing this extension. Keep improving it.
