Wow, this is incredible. I've been avoiding firefox quantum tab management addons as they've always been pretty poor compared to the ones I used to use in firefox back in the day. But I'm glad I tried this, it's incredibly visual.

Superb Extension, 5 stars is not enough for this. Keep up the good work for the mass people. Thanks.

Since I discovered this extension it became an indispensable tool for me and I am glad that the developer agreed to port it to Firefox- I have tested about a dozen tab managers and I find Tab Manager Plus the handiest and the most customizable one. Tab Manager Plus is open source and developer responds usually quickly to bug reports and feature requests.
