The Tab Limiter

Limit the number of open tabs – in total and per window

Tab limiter helps you get back control over your browsing – by limiting the number of tabs you can open at once.

You can specify the number of tabs in total and per window. Moreover, you can show a customizable message when the tab limit is hit.

ps: This is a fork from https://github.com/juni-vogt/tab-limiter

I really love the extension and want to stay using
