Hemanta Adhikari (ID: 0000005b7759f64b) Voted 4 ★ - Updated 12/22/2022 Thank you for making this. This is awsome. However, I encountered a serious issue (at least for me). I wanted bookmarks bar to be shown ONLY in NEW tab. This extension is preventing that.

Danijela Djuric Petrovic (ID: 000000b645c83366) Voted 5 ★ - Updated 12/14/2022 Great idea and it really helped me while learning. It would be better with a bit more languages.
