An essential addon for the freaks of navigation tabs, like me. It is a tool that contributes greatly to productivity and organization when the amount of tabs verge of chaos. Thank you @piro_or for this great work!

This extension is THE ONLY THING THAT MAKES FIREFOX USEABLE. Other browsers don't have it, and using them is like pulling teeth. However, it was no longer valid with the most recent update of FF and wasn't working. To fix it I just did a temp uninstall of FF and when I reinstalled it was back.

Super!!

Awesome plugin. Using it for years.
Also faced issue with signed one "Internet connection issue" Not able to update.

This was excellent, but today has suddenly disappeared and I can't re-download it. I get 'Download failed. Check your internet connection'. Please fix it! It's so much better to have my tabs at the side....But then, while writing this, it has suddenly reappeared!!! Thank you for this app. :)
