Как оказалось расширение блокирует контент на страницах некоторых сайтов. То есть на страницах не открывается содержимое. Жаль,пользовался давно и вынужден отказаться.

This is an excellent add-on!

My only problem is:

When multiple windows are open, the download bar will display on all of the windows.

I separate windows to watch videos in full screen mode on a different monitor and the download bar blocks half of the functions on Youtube.

Pressing "Esc" will exit full screen mode, but I try to avoid doing this until the video is done.

No more picture preview in mouse over, bar flashing when clearing downloads.

Well, I mean, I want to translate this addon and I can't find place to do this

Used this for years, then it disappeared. Glad to see it back.

Mozilla 57.0.2 good job
