я все настроил под себя и сейчас наслаждаюсь главной страницей

I like this one, tho :) Earlier, I was using Bonjourr, but this has more minimal approach. On Chrome, I used MYNT, which was both highly customizable and minimal. However, tabliss is just clean, making my Firefox desktop setup look cool. I just hope they add support for mobile too!

я не знаю зачем оно существует я перебрал все настройки и оно буквально бесполезное

Amazing extension, visually stunning with upload animation backgrounds! With these improvements, it truly wouldn't have any competition. However, while it has many features that are functional, some of them look a bit too geometric for my taste. It would be a huge improvement if the links/bookmarks feature could become more customizable: right now they only stack vertically. It would be fantastic to have grouping capabilities (with categories and custom icons for each group) and flexible layout options instead of a strict vertical column like bonjourr.
EDIT: IP not appear any more, so uninstalled it until you will fix it

Very pretty images

The most sleek and clean new-tab extension you can find. Sadly not maintained anymore, what is a dealbreaker for me. If you want to check out the extensions install TABLISS-NG instead. It's actively maintained and has new features not present in the original extension. Plus bugs have been solved :)
