Wow. Father of the Year!
Works great. Prevents a self administered headache I've suffered for years.
And proud to rock an add-on that's an act of love.

Made me a bit frustrated at first, when I noticed that all my pinned tabs are gone, but the developer responded immediately and fixed it, so I'm editing my review to tell that the extension works like a charm, saving my time and computer resources. Great job!

Update: developer added feature :-)

Works great on Firefox for Android.
Would be nice to have an option to disable the annoying 'ping' sound when you try to go over the tab limit.

Good one, does what is said, however, it would be great if you could integrate tab limiter and tab counter - in this way I need to have open another extension which is counting tabs, and yours, which prevents more than desired to be open. Before this major Firefox change, there was a great tool doing exactly that, and I still can't find those two functions integrated.

In any way, thanks for a nice add on!

Edit: One more star after last version

Hey hey.. Please make an option for no sound and add more funny ones (or less scary) as well :) Thank you for great extension

Excellent extension. Thank you! This will help the rest us who cant stop diving into the infinity pool that is the internet every day.

PS: You are a good father

Thanks

would be nice to have an option for disable the sound

Awesome. Just Awesome.
To get Awesome indeed rating from me, which is even more awesome than Just Awesome, consider this;

-Pinned tab should have an option to ignore them
-Include some kind of obvious visual alert, when new tabs aren't allowed to be open anyomore. For all of us having sound turned off. :D

Much appreciated, Mr. Rudolf!

The sound for trying open a tab in excess is strange at first, but it keeps kinda funny while being a real alert! And the main limit is just flawless! Thanks! Hope everything goes well for you and your son! :)

I love it. It would be nice for there to be an option to add a button to the address bar that would allow you to change the number of tabs allowed or toggle it on and off more easily.

A life-saver for me. I happily avoid too much procrastination because of this.

Jesus would approve this add-on

Great! Anyway to change limit?

Awesome!
