Why don't you keep past versions in history?

Почему в истории не сохраняете прошлые версии?

Certainly must have...

Easy to use, customize, and see. Nice button choices.

спасибо за добросовестную заморочку, на сколько я придирчивый, но с твоим скролом нашли общий язык.. )) даже понравился..))

Position of the arrow would not change despite settings

Scrolling Speed Lowest it's still to fast for me set % speed shoud be great, scale icons size can ba added.

This is such a great extension, makes it so easy to get back to the top of pages after scrolling all the way to bottom.

I have been using this extension for a long time on Chrome but when I switched to Firefox I can't get the arrows to disappear when YouTube is fullscreen. It's driving me nuts. Love the extension other than this. Any help would be appreciated. Thanks.

I've had this extesnion for a long time and still use it in my 32 bit Firefox v 39 and just found it for the 64 bit v56 install which was something this install was missing.

The best and easiest to use add-on! Ever! Recommend it to anyone, who's willing to be smart and practical. You'll love it!
