This is the tab/session manager I have been looking for. Awesome features all in one extension. Easy import/export. Superb and clear GUI design. Finally I can remove the various tab managers and separately the extension managers I have been using so far. And best of all - it is free/libre/open-source software with no ads, tracking or "if you want the full features pay $$ here..." gimmicks.

Have been using it now for a few weeks both in Chrome and Firefox. No issues. Does exactly what it is designed to do. More features coming hopefully in due time ...

Cudos and much gratitude to the the developer and contributors. - 5 stars :-)

Intuitive and enjoyable. Very good idea. I just started to use it and I think I will soon cannot do without. Pinning from here is great. I did not test all the features yet like search, order etc. but I guess they are most welcome, too. Thanks a lot.

Beautiful and powerful, especially necessary for firefox's new-tab page.

F-ing awesome! It has it all:
1. Dark background for new tab. No more burning out my eyes with goddamned white backgrounds.
2. You can create custom themes. Just the kind of thing I like. I can spend day tinkering with browser/sites appearance, really. Thank you for this option.
3. It allows to search through opened tabs (there are several extensions with this functionality, but Tab Master 5K has one of the best visual representations of it).
Thank you, dev, my life has just got better thanks to you.
