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.

Works fine and according to its own description is highly optimized. But the font size is pretty small and not customizable. E.g. Tab Counter Icon is much better in this regard.

Works, but the number is way too small where there are > 1000 tabs, and there is no way to increase it, despite the large amount of empty wasted space around it.

Needs to update text/numbers color on dark mode.

Najlepszy!

Thank you. Fast and helpful.

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!
