В версии 3.0.0.17 тоже утечка памяти. Дмитрий, исправьте, пожалуйста.

The row of buttons under the video player like Save, Clip etc, sometimes get automatically collapsed into the overflow menu when Return YouTube Dislikes is enabled.

When this happens only the Share button remains visible on-screen. Refreshing the page brings back the Save, Clip etc buttons, but it's a UI bug that needs fixing.

does what it says

Good extension for YouTube

Working as intended.

It used to work well, but now makes Youtube laggy.

Edit: Fixed.
