ScrollAnywhere by Juraj Mäsiar

Scroll Anywhere enables you to drag scrollbar with your middle (or right / left) mouse button without actually touching a scrollbar. Just hold the middle mouse button and move up-down or left-right. You can also change the behavior to simple "grab and drag" style.

Available also for your Thunderbird 78 email client!

• does not work on browser specific pages like "about:addons" (blocked by Firefox)

Be aware:

• left mouse button support is experimental feature - please report any issues to my support e-mail.
• Linux users may want to enable "Don't block default button action" option in Options/Advanced - to enable 'Paste' with middle button again.
• in some Linux versions you may need to disable "middlemouse.contentLoadURL" in "about:config" to avoid navigating to URL from clipboard when pressing middle mouse button
