Hi Panurg

go to about:config find

general.smoothScroll.lines.durationMinMS right-click on it, select modify and change the value to 1500 , click OK to save it

do the same with general.smoothScroll.lines.durationMaxMS and check it again.

check the scrolling with your up and down arrows and select a value, i think something between 1500 and 2000 is ok for you.

thank you

This did solve the issue - partly...

In fact, the scrolling still isn't a proper scrolling, but is somewhat jerky, uneven, - - - but slower so. I would appreciate an evenly-speeded motion, as it comes when permanently held the arrow-field at the vertical scrollbar's ends.

Done ages ago ;-} Neither of these affect the "scroll" behaviour as described. I found out that I ask for a key shortcut for the small square arrow fields on both ends of the (vertical) scroll bar. Only these, klicked-and-held, trigger what I call scrolling. The speed of this scrolling is indeed set by general.smoothScroll.scrollbars.durationMaxMS general.smoothScroll.scrollbars.durationMinMS

Um... Have I unawarely said Jehova?? I assume the difference between scrolling and cursor shifting to be quite obvious. There are browsers where the UP/DOWN arrow keys are scroll-keys by default. In Firefox they are cursor shift keys. Is this a default that could be altered (e.g. to "scroll"), or is this a fix assignation? If the latter: Would it be possible to re-program this?
