This is beyond useful, especially with the userchrome.css rules that people tend to recommend at the same time as it. This changes the whole tab-management game, why isn't this built in to everything by now?

So useful. Thanks

If there is one extension you should consider, this is it. This is the main reason I use Firefox. I won't consider any other browser because of TST. No other browser has anything this fabulous. I started using the basics of TST as soon as I installed it. Over time, I began customizing it by adding more and more of its functions and making it even better.

Best add-on I had EVER for Firefox. Stable, dependable, well-featured, well-documented. Not to mention it solves a problem (moving to 16:9 screens from 4:3) which browsers should have solved in the last 15 years, but ALL of them FAILED.

非常好用方便

This might be a really weird comment, but I really wonder why there is no copy of this extension on Chrome?

This add-on has become very useful now that I do all my work from home. Everything works well and is easy to customize.

One of the best extension I use! Using a normal browser become a pain without it. Thank to Piro for making it (and for the hard work involved in porting it to webextension)

Great extension
