Works really well, auto-hides scrollbar in the latest firefox. However, if you browse to an old reddit subreddit that uses a custom old subreddit style, like /r/ffxiv, the custom style will scroll with the page, detached from the subreddit.

It is also incompatible with current YouTube, and disallows scrolling on YouTube.

Doesn't work as intended. On YT, for example, in would only scroll the left column with a mouse wheel, while the main window is unscrollable.

與火狐自帶的右鍵截圖有衝突：截圖時候滾動滑鼠滾輪失效。

Really great, but I would love to be able to chose a color instead of having a random color. Also, having a black-list to disable the addon on some website would be great, it's making Google Photos looks weird.
But beside that I love it!

can't load photos in instagram page with this scroll bar.

So great! Wish there was an option to change scroll bar height/color. But otherwise, an absolutely perfect hidden scroll bar implementation! Full-Screen browsing is so much better now! Thank you!

Update: As some have mentioned, it completely blocks scrolling through any means on sites like YouTube. :( And there's no add-on icon to allow enabling/disabling for specific sites. :( Sad panda. This was almost perfect.

作者还维护这个扩展吗？十分期待更新支持翻页类扩展

Youtube无法滚动，请问这个能修复吗？

Not working in YouTube on FF64

only this scroll bar works in lastest version

Working on firefox 58 , just enable legacy extensions in about:config. Thank you

希望能尽快修复页面无法滚动的问题 谢谢！

大部分页面都是OK的，有一小部分页面会造成无法滚动(比如steam社区市场、腾讯游戏主页)。

尽快修复页面无法滚动的问题

Good, but not works on Youtube. (I cannot scorll the page on Youtube)

funktioniert 1a auf ffquantum , optisch sehr gut !

This is great and sorely needed, however the issues with it not working on "autopage" sites - and messing with the layout of certain other sites - really do need to be fixed. I can't honestly describe this add-on as usable in its current state. On another note, customisation options for colour/transparency of the scrollbar would be nice to have.
