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! Short preview video here (0:12) Warning: very addictive! :) Features:

Momentum allows you to throw page to scroll it faster (just like on your phone)
Middle / Right / Left mouse buttons are supported, see the Options page
Customize scrollbars - make them thinner, change color or hide
Auto-disable on specified domains / sub-domains
Grab and drag scroll like on your phone
Multiplier to speed-up or slow down
On key down enable / disable
Custom scrolling cursor

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
