Thanks SO much for having published this under Apache 2.0 license!!

Works well, does what I need without noticeable slowdowns at dozens or even hundreds of tabs. I've never run into any issues, never had to dig deep into settings to solve problems. Exactly what I look for in this kind of extension.

Najlepszy!

Thank you. Fast and helpful.

Does what it's supposed to do and nothing more. Neat.

works fine

Super useful for us, tab hoarders with 250+ tabs opened... This is kind of sad, but this extension is not to blame!. I recommend moving it from the address bar level to tabs strip and disabling it vis userChrome.css when you have non-overflown tabs!

Cool little helper. Informs me with the exact number of tabs open. THIS is what I wanted.
An improvement would be if I could define a number for alert notification. (even wording I enter :)
example: 20+ Hello, 40+ WaytoGo!, 60+ Caution!, 80+ Nuts!
I am at 108 right now, I need to come down.

Works as expected and the best tab counting add-ons I tried out

It perfectly does everything it should do.

Great light weight extension for those who multitask and have hundreds(sometimes thousands of tabs open). Still some "customizablity" I think could be improved in regards to sizing the font or perhaps changing the size. It is very functional as is however as is, and have been using it for a long time after relacing another tab counter. Thank you oriol.

thinks,I like this extension
