Grrreat!!!

Linux user here; this perfectly solved my touchscreen scrolling issue within firefox! The customization options are wonderful and allowed me to set it up just how I wanted.

I have one suggestion:
I use the left mouse button to scroll. However, it's hard to select text, text lines by horizontal mouse movement.
So it would be nice to have an option to disable the scrolling for this purpose – maybe by using a horizontal mouse movement detection with slight tolerance for vertical movements?

thx for thin scrollbar

Overall good but when using right button to scroll, the context menu pops up frequently (Firefox 75.0 64-bit, Windows 10 1909)

perfect! absolutely no complains.

このアドオンは、IllustratorやPhotoshopの手の平スクロールと同じようにWEBページや大きい画像を自由にスクロールさせることが可能です。便利。
ありがとうございます。

問題点
①設定画面のＵＩが英語なので、非英語母語話者は理解が難しい。
②右ボタンドラッグ、ホイール無効、この設定の場合。マウスドライバによっては誤動作します。
マウスホイールで上下スクロールしたとき、高頻度で一瞬反対方向に小さくスクロールしてしまいます。
私はいくつかのマウスで試しました。
このアドオンを無効にするとホイールスクロールは正常になりました。

This add-on allows users to freely scroll web pages and large images just like palm scrolling in Illustrator and Photoshop. Useful.
Thanks a lot.

Issues
①The UI of the setting screen is in English, so it is difficult for non-native English speakers to understand.
②Right button drag, wheel disabled, in case of this setting. It malfunctions depending on the mouse driver.
When scrolling up and down with the mouse wheel, it scrolls small in the opposite direction for a moment with high frequency.
I tried with some mouse.
When I disabled this add-on, wheel scrolling became normal.

Incredibly useful and well designed

Amaizing.
Two ideas:
- if you disable the addon via hotkey or don't use middle mouse button to activate it, it would be logical to be able to use the original functionallity of m3. (Edit: I realised it works, I just accidentaly disabled autoscrolling in the Firefox options)
- while scrolling have a hotkey to reset where you were on the page before clicking, just like with the regular scrollbar if you drag the cursor outside of it's range.

Wow surprisingly good on Ubuntu-MATE 19.10/ FireFox 73.0
I am already addicted. Also with the default setting it does NOT remove the paste with the wheel (I was scare about that so it was the first thing I did tried, and got very happy), Excellent!
I like also your humor in the setting page (1000 grams, it's funny;) )

Very nice add-on, thanks-thanks a lot!

Works like a charm! Beats the hell out of using the mousewheel.
